ABSTRACT

Gujarat Government has come up with new mining rules having auction policy which is fair, transparent, non-discriminatory and in line with the Supreme Court and high court orders for the allocation of natural resources. According to New rules of Gujarat Minor Mineral Concession rules 2017 the potential area of quarry lease shall be identified and demarcated using DGPS and shall have a topographic and geological map prepared using total station. Also as per part-A geological study report is required in which evidence of mineral resources shall have been established for the block to be auctioned. So this study is required for the auction purpose of a blacktrap block at village Sonpari. Exploration of the said project was done on October 2017 for the estimation of the reserves. After carrying out G2 stage (General Exploration) exploration a total 23, 62, 880 metric tons reserves of blacktrap has been estimated assuming total 20 mtr thickness of the deposit. The deposit of blacktrap is huge and as it is nearer to the proximity of city like Bhavnagar and where transportation cost is less and demand is more so it is good block for auction.

CHAPTER I

INTRODUCTION

Bhavnagar district is one of the most developed of region of Gujarat State. Its district headquarter is located in Bhavnagar city. Bhavnagar was founded by Bhavsinhji Gohil (1703-64 AD) in 1723 AD near the Gulf of , on a carefully chosen strategic location having potential of maritime trade. has the area of 9980.9 Sq km and is located in southern part of the Saurashtra Region of Gujarat State. It lies between north latitude 210 18’ and 22018’ and east longitudes 710 15’ and 720 18’. It falls in the Survey of (SOI) degree sheets 41 O and 46 C. District Bhavnagar is bounded by Surendranagar and districts of Gujarat in the north, Rajkot and districts of Gujarat in the west, Arabian Sea and part of in the south and the Gulf of Cambay (Gulf of Kambhat) in the east. Bhavnagar District is divided into ten talukas: Bhavnagar, , Umarala, Gariyadhar, Palitana, Mahuva, Talaja, , Jesar and Vallbhipur. [4] There are close to 800 villages in this district. The Minerals found in the district are Gravel, Ordinary sand, clay, Blacktrap, Lignite, Laterite, ,which are commonly used in the construction of residential buildings and industrial houses and business complexes or huge Shopping Centers and other infrastructure projects. Blacktrap has long been used as aggregate for construction of roads and building. Today, the demand for these materials continues to rise. Gujarat Government has come up with new mining rules having auction policy which is fair, transparent, non- discriminatory and in line with the Supreme Court and high court orders for the allocation of natural resources. According to New rules of Gujarat Minor Mineral Concession rules 2017 the potential area of quarry lease shall be identified and demarcated using DGPS and shall have a topographic and geological map prepared using total station. Also as per part-A geological study report is required in which evidence of mineral resources shall have been established for the block to be auctioned. So this study is required for the auction purpose of a blacktrap block at village Sonpari.

CHAPTER II

GEOLOGY a) Brief descriptions of Regional Geology with reference to location of lease/applied area:- The physiography of the district varies from place to place. It ranges from the coastal marshes and sandy areas fringing the Gulf of Cambay (Khambhat) to the hilly areas of Palitana and Sihor in the south and southeast and and in the northwest. In the north-western parts of the district, hilly upland area ranges between 100 and 296 m above mean sea level (amsl) and the regional slope of the district is towards east in this parts. The height of the hill ranges in the south and southwest covering Palitana and Sihor talukas generally range from 305 and 457 m amsl. The Shetruji hills lying southwest of Palitana have the highest elevation (501 m amsl) in the district. These hill ranges lies almost parallel to the coast in a southwest - northeast direction and covers the south central part of the district of Bhavnagar. The regional slope is towards east and southeast. The regional slope of the land is towards south in the area lying south of the hill ranges upto the coast in the southern part of the district covering major part of the Muhava taluka, resulting in the river flow direction towards south in this part. Apart from the above hill ranges of the northwest and south central parts of the district, there are two distinct physical regions in the district, namely (1) the coastal plain including the adjacent sand banks and (2) the inland plains. The coastal plains is broken with rocks and hillocks featured by several creeks along the coast while the plains in the interior are flat in places and undulating and broken by hills in other places. The hills near (109 m amsl) and Shogadh (86 m amsl) in the northern plain raises abruptly above the plain breaking its monotony Geologically, 80% of the area is covered by Basalts and the remaining 20 % by alluvial formation and mudflats. The generalized geological succession is given in the following table:

9 | Page Vill: - Sonpari , Tal. – Palitana , Dist.: Bhavnagar . BLACK TRAP BLOCK – D AREA: - 04.16.00 hect.

TABLE NO. 3 – Regional Geology

Era Age Formation Lithology Quaternary Recent to Surface Thick beds of SubRecent Soil/ calcareous clay, Alluvium intercalated with layers of trap sand --Unconformity-- Tertiary Lower Deccan Basalt as stratified Eocene to trap lava flows Upper comprising Cretaceous amygdaloidal basalt, fine grained porphyritic basalt and basaltic/dolerite dykes.

b) Geomorphology of the area

Regionally area is located on trappean rock which belong to the large igneous province known as Deccan Trap, comprises of dominantly basaltic lava flow of Upper Cretaceous to lower Eocene period. The basaltic terrain forms ridges, hillock and plateaus with lineaments/fractures. These lineaments/fractures show cress-cross pattern. NE-SW & E-W are the major tread of lineaments/fractures. The block is located at eastern end of extensive watershed of Lake Reservoir Shetrunji. Other smaller lakes reservoir nearby are block are Kharo and Rajawal lakes. The block is located on slop of ridge nearby the lake reservoir Kharo, the ridge is barren with only scattered vegetation. The ridge is 80 to 100 m high, with rounding undulating surface topography. The slop of ridge is eastward. NE-SW tending lineament and fine fracture/cracks on slope present in the block. Local streams are flowing along the lineaments and fractures. Regionally the area has similar ridges whereas the rest of area is flat or gently sloping used for agricultural purposed. c) Local Geology:-

Geologically the area comprises of Blacktrap (Basalt) of Deccan trap age.

The mineralized zone is geo-referenced and delineated with the help of DGPS machine which is 41,600 sq. Meter. Regionally blacktrap is having more than 20mt. depth. The weathered portion is found mostly up to 2mtr. Reserve calculation has been done using the regional depth of blacktrap up to 20meter.

CHAPTER III

EXPLORATION

a) Topographic and geological survey

As per pre-requisites condition of GMMCR-2017 rule 4 the area under study has to be identified and demarcated using Differential Global Positioning Systems (DGPS) and shall have a topographical and geological map prepared using total station. Direct acquisition of elevation data is an important aspect of topographic studies. Differential Global Positioning Systems (DGPS) provide an accurate and efficient method of obtaining elevation data. DGPS surveys are capable of recording data in three dimensions (latitude, longitude and elevation). During the field survey the points were collected in 5 meter grid using the RTK-DGPS. DGPS survey data has been imported to geographic information system (GIS), where survey points are converted to digital terrain model (DTM). The topographic plan of the lease area has been prepared on a scale of 1:1000 with contour interval of 5 m. (Plate No. IV). The Lease area is having a maximum height of 100 meters and minimum height of 30 meters. Geological mapping had been done in the area at the 1:1000 scale. The area was covered with blacktrap deposits. b) Details of Blacktrap Deposit

There are many existing blacktrap quarries around this block area, in which blacktrap is mined upto 20 m from ground level in these quarries. Therefore, it can be safely said that the depth of blacktrap deposits in the block area is more than 20 meters. c) Sampling technique

Trap is dominantly black in colour, also commonly known as black cotton soil. A sample was collected from block area. Location of the sample is as follow

CHAPTER V

RESOURCE ESTIMATION

Bhavnagar district contains huge deposits of blacktrap mineral. The block area is located at Bhavnagar District. Surface geological studies reveal blacktrap is deposited in the entire block more than depth of 20m. considering this as base as per GMMCR 2017 Schedule I, the resource estimation has been done. The block area is demarcated using dGPS. The resources has been classified as 332 (Indicated Mineral Resource). a) Assumption made for resource estimation

The resources of the quarry lease area is estimated considering the blacktrap up to the depth of 20 meter as indicated mineral resources (332) as per GMMCR-2017 schedule-II. b) Method Adopted for Resource Estimation:

As the block area having undulated topography and as per Gujarat Minor Mineral Concession Rule-2017 depth of the mineral resources above 20 meter is considered for reserve calculation so following table shows the resources calculation. The resources are categorized in indicated mineral resources (332) categories as the deposit is found up to 20 meters depth.

TABLE NO. 5 – Indicated Mineral Reserve Table

Total Area Depth Volume Sp. Tonnage (Sq. Mt.) (Meter) (Cu. Mt.) Gravity (Vol. * Sp. Gr) 41,600 20 8, 32, 000 2.84 23, 62, 880
