INTRODUCTION

Afghanistan is endowed with abundant natural resources that remain largely untapped. The country has world-class deposits of iron ore, copper, gold, rare-earth minerals, and a host of other natural resources. Similarly, the presence of petroleum resources has long been known in Afghanistan but these resources were exploited only to a limited extent.

Bulk metals, such as iron ore, copper, aluminum, tin, lead and zinc, are located in multiple areas of the country. And, gemstones, rare-earth metals, sulfur, talc, gypsum and chromite, are predominant across Central Afghanistan, Baghlan, Kunduz, Logar, Khost, among other places.

Much of the petroleum resource potential of Afghanistan and all of the crude oil and natural gas reserves are in northern Afghanistan, located in parts of two petroliferous geologic basins – the Amu Darya Basin to the west and the Afghan Tajik Basin to the east.

The Government of Afghanistan sees Afghanistan’s vast mineral and hydrocarbon resources as a catalyst of long-term economic growth. Accordingly, the Ministry of Mines and Petroleum (MoMP) designed several consequential documents, including the Mining Sector Roadmap, a new Minerals Law, and a new Hydrocarbons Law as part of its commitments to open the mining and hydrocarbon sectors for private investment.

To sustainably utilize our natural resources, the Ministry of Mines and Petroleum intends to tender new large-scale mining and hydrocarbon projects. The ministry is rigorously focused on attracting domestic and foreign investors to exploit Afghanistan’s plethora of mineral and hydrocarbon resources. This document will focus on the bankable investment opportunities in the mining sector which are ready for tendering. Band-e-Amir National Park, Bamyan — Photo Credit: Dr. Hassan Malestani

66° This map shows the distribution of selected carbonates, phyllosilicates, 62° sulfates, altered minerals, and other materials derived from analysis of HyMap 64° imaging spectrometer data of Afghanistan. Using a NASA (National Aeronau- tics and Space Administration) WB-57 aircraft flown at an altitude of ~15,240 meters (m) or ~50,000 feet (ft), 218 flight lines of data were collected over 36° Afghanistan between August 22 and October 2, 2007 (Kokaly and others, 64° 2008). The grayscale background image, visible in the area of no data around 36° the country’s perimeter, is from Landsat Enhanced Thematic Mapper Plus (ETM+) (Davis, 2007). The HyMap imaging spectrometer measures 128 channels of reflected sunlight at wavelengths between 0.4 and 2.5 µm (Cocks and others, 1998). The HyMap data were converted to apparent surface reflectance using ACORN (Atmospheric CORrection Now) version 6lx software (developed by ImSpec LLC), then further empirically adjusted using ground-based reflectance measurements. Each flight line was georeferenced to Landsat base imagery in Universal Transverse Mercator projection (Davis, 2007). HyMap reflectance data were processed using MICA (Material Identification and Characterization Algorithm), a module of the U.S. Geological Survey 62° PRISM (Processing Routines in IDL for Spectroscopic Measurements) software (Kokaly, 2011). Subsequently, the classified HyMap results were projected to a Transverse Mercator projection and mosaicked, with 23-m pixel spacing. Using MICA, the reflectance spectrum of each pixel of HyMap data was compared to the spectral features of reference entries in a spectral library of minerals, vegetation, water, ice, and snow. For each pixel, MICA determined the reference material having the best matching spectrum. MICA analysis resulted in a “Not classified” determination for a pixel when comparisons with reference spectra produced no viable match (see Kokaly, 2011). This map shows the spatial distribution of minerals that have diagnostic absorption features in the shortwave infrared wavelengths. These absorption features result primarily from characteristic chemical bonds and mineralogical vibrations. A complementary map showing the distribution of iron-bearing minerals and other materials having diagnostic absorption features at visible and near-infrared wavelengths has also been created (King and others, 2011). Several criteria, including (1) the reliability of detection and discrimination of minerals using the HyMap spectrometer data, (2) the relative abundance of minerals, and (3) the importance of particular minerals to studies of Afghanistan’s natural resources, guided the selection of entries in the reference spectral library and, therefore, guided the selection of mineral classes shown on this map. Minerals occurring abundantly at the surface and those having unique spectral features were easily detected and discriminated. Minerals having similar spectral features were less easily discriminated, especially where the minerals were not particularly abundant and (or) where vegetation cover reduced the absorption strength of mineral features. Thus, some map classes include several minerals having similar spectra, for example, the “Chlorite or Epidote” class. In addition, some identified minerals were grouped to reduce the total number of classes, in order to allow the assignment of discernible map colors. Complications in reflectance calibration also affected the detection and identification of minerals. Complications arose because of (1) the large magni- tude of the imaging spectrometer dataset, which covers an area over 480,000 km2, (2) surface elevations that range from 280 to 5,642 m (920–18,510 ft), 34° and (3) a protracted data-collection period lasting 43 days. In addition, varia- 34° tions in daily weather, in solar angles, and in airborne dust levels affected reflectance calibrations. In cloud-contaminated areas, it was not possible to completely remove atmospheric effects in the conversion of the data to reflec- tance because of significant variation in water-vapor content of the atmos- phere. As a result, some differences in identified material classes exist between adjacent flight lines that differed in extent of cloud cover. Similarly, minor differences in identified material classes occur between adjacent flight lines having large differences in solar illumination angles (see Kokaly and others (2008) for flight-line data collection times and dates). On October 2, 2007, the last day of data collection, a large dust storm blanketed southern Afghanistan (see Kokaly and others, 2008). No correction for airborne dust, beyond exten- sion of the ground calibration factor, was applied to the data collected along these lines. Hatched lines identify areas where mineral identification was adversely affected by soil moisture. Material classification in these areas is less accurate due to the distortion of reflectance spectra by the strong absorption of light in the infrared wavelengths by the water in the soil. In some limited areas, the MICA analysis misidentified wet, bright soils as snow, because both are highly reflective in the visible wavelengths but are strongly absorbing at longer wave- lengths. Pixels classified initially as snow-covered for land surfaces whose elevation is lower than a threshold elevation of 3,150 m (10,334 ft) were reclassified as wet soils. EXPLANATION OF MATERIAL CLASSES The 31 classes in the list of materials represent a necessary compromise 70° between striving for the highly focused level of detail achievable in the best [Some material classes which have small areal extent calibrated flight lines, on the one hand, and, on the other hand, seeking identi- may not be visible at the publication scale of this map] fications that were reliably detected across the entire country and that occurred in large enough areas to be perceptible at a national map scale. Each class name specifies a mineral, or several minerals, whose reflectance spectra match Calcite (abundant) the HyMap data. However, minerals having slightly different chemical compo- sitions may have very similar reflectance spectra. Therefore, the material Calcite classes represented on this map should be evaluated giving consideration to the effects of mineral chemical composition on reflectance spectra.

66° 62° DATA SUMMARY 64° This map shows the distribution of selected iron-bearing minerals and other materials derived from analysis of HyMap imaging spectrometer data of Afghanistan. Using a NASA (National Aeronautics and Space Administration) 36° 64° WB-57 aircraft flown at an altitude of ~15,240 meters (m) or ~50,000 feet (ft), 218 flight lines of data were collected over Afghanistan between August 22 36° and October 2, 2007 (Kokaly and others, 2008). The grayscale background image, visible in the area of no data around the country’s perimeter, is from Landsat Enhanced Thematic Mapper Plus (ETM+) (Davis, 2007). The HyMap imaging spectrometer measures 128 channels of reflected sunlight at wavelengths between 0.4 and 2.5 µm (Cocks and others, 1998). The HyMap data were converted to apparent surface reflectance using ACORN (Atmospheric CORrection Now) version 6lx software (developed by ImSpec LLC), then further empirically adjusted using ground-based reflectance measurements. Each flight line was georeferenced to Landsat base imagery in Universal Transverse Mercator projection (Davis, 2007). HyMap reflectance data were processed using MICA (Material Identification 62° and Characterization Algorithm), a module of the U.S. Geological Survey PRISM (Processing Routines in IDL for Spectroscopic Measurements) software (Kokaly, 2011). Subsequently, the classified HyMap results were projected to a Transverse Mercator projection and mosaicked, with 23-m pixel spacing. Using MICA, the reflectance spectrum of each pixel of HyMap data was compared to the spectral features of reference entries in a spectral library of minerals, vegetation, water, ice, and snow. For each pixel, MICA determined the reference material having the best matching spectrum. MICA analysis resulted in a “Not classified” determination for a pixel when comparisons with reference spectra produced no viable match (see Kokaly, 2011). This map shows the spatial distribution of iron-bearing minerals and other materials having diagnostic absorptions at visible and near-infrared wave- lengths. These absorptions result from electronic processes in the minerals. A complementary map showing the distribution of selected carbonates, phyllosili- cates, sulfates, altered minerals, and other materials having diagnostic absorp- tions in the shortwave infrared wavelengths has also been created (Kokaly and others, 2011). Several criteria, including (1) the reliability of detection and discrimination of minerals using the HyMap spectrometer data, (2) the relative abundance of minerals, and (3) the importance of particular minerals to studies of Afghanistan’s natural resources, guided the selection of entries in the reference spectral library and, therefore, guided the selection of mineral classes shown on this map. Minerals occurring abundantly at the surface and those having unique spectral features were easily detected and discriminated. Minerals having similar spectral features were less easily discriminated, especially where the minerals were not particularly abundant and (or) where vegetation cover reduced the absorption strength of mineral features. Thus, some identified classes consist of several minerals having similar spectra, such as Fe3+, type 1, and Fe3+, type 2, in which the primary difference between them is the width of the absorption feature. In addition, some identified minerals were grouped to reduce the total number of classes, in order to allow the assignment of discern- ible map colors. Complications in reflectance calibration also affected the detection and 34° identification of minerals. Complications arose because of (1) the large magni- 34° tude of the imaging spectrometer dataset, which covers an area over 480,000 km2, (2) surface elevations that range from 280 to 5,642 m (920–18,510 ft), and (3) a protracted data-collection period lasting 43 days. In addition, varia- tions in daily weather, in solar angles, and in airborne dust levels affected reflectance calibrations. In cloud-contaminated areas, it was not possible to completely remove atmospheric effects in the conversion of the data to reflec- tance because of significant variation in water-vapor content of the atmos- phere. As a result, some differences in identified material classes exist between adjacent flight lines that differed in extent of cloud cover. Similarly, minor differences in identified material classes occur between adjacent flight lines having large differences in solar illumination angles (see Kokaly and others (2008) for flight-line data collection times and dates). On October 2, 2007, the last day of data collection, a large dust storm blanketed southern Afghanistan (see Kokaly and others, 2008). No correction for airborne dust, beyond exten- sion of the ground calibration factor, was applied to the data collected along these lines. Hatched lines identify areas where mineral identification was adversely affected by soil moisture. Material classification in these areas is less accurate due to the distortion of reflectance spectra by the strong absorption of light in the infrared wavelengths by the water in the soil. In some limited areas, the MICA analysis misidentified wet, bright soils as snow, because both are highly reflective in the visible wavelengths but are strongly absorbing at longer wave- lengths. Pixels classified initially as snow-covered for land surfaces whose 70° elevation is lower than a threshold elevation of 3,150 m (10,334 ft) were reclassified as wet soils. The 27 classes in the list of materials represent a necessary compromise between striving for the highly focused level of detail achievable in the best- calibrated flight lines, on the one hand, and, on the other hand, seeking identi- fications that were reliably detected across the entire country and that occurred in large enough areas to be perceptible at a national map scale. Each class name specifies a mineral, or several minerals, whose reflectance spectra match the HyMap data. However, minerals having slightly different chemical compo- sitions may have very similar reflectance spectra. Therefore, the material EXPLANATION OF MATERIAL CLASSES classes represented on this map should be evaluated giving consideration to the [Some material classes which have small areal extent effects of mineral chemical composition on reflectance spectra. may not be visible at the publication scale of this map]
