Email: [email protected] Abstract This paper focuses on presentation of the methodology used by geophysicists at the Servicio Geológico Colombiano (SGC) for the processing, anomaly selection and interpretation of airborne magnetometry and gamma spectrometry data. Three (3) selected magnetic anomalies from different geological settings (Andes Cordillera, San Lucas Range and Ama- zon region) are presented as examples. 3D magnetic vector inversion (MVI) modeling of each of the selected magnetic anomalies shows magnetic sources less than 100 m deep or exposed with sizes from 2.5 to 6 km. The magnetic data inter- pretation also allows the identification of linear features that could represent structural control for fluid migration and/ or ore emplacement. Additionally, the integration of the geophysical data with other geoscientific information (geologic, metallogenic and geochemical data) leads to the proposition of an exploration model for each anomaly: intrusion-related/ VMS deposits for the Andes, porphyry/intrusion-related/epithermal deposits for San Lucas and carbonatite/kimberlite for Amazonas.

Email: [email protected] This is a non-peer reviewed preprint and has been submitted to Global Planetary Change (Special Issue). Keywords: River capture, surface uplift, knickpoint migration, tropics, biodiversity 1 Abstract The tropical Northern Andes of Colombia are one the world's most biodiverse places, offering an ideal location for unraveling the linkages between the geodynamic forces that build topography and the evolution of the biota that inhabit it. In this study, we utilize geomorphic analysis to characterize the topography of the Western and Central Cordilleras of the Northern Andes. We supplement our topographic analysis with erosion rate estimates based on gauged suspended sediment loads and river incision rates from volcanic sequences. In the northern Central Cordillera, an elevated low-relief surface (2,500m in elevation, ~40x110 km in size) with quasi-uniform lithology and surrounded by knickpoints, indicates a recent increase in rock and surface uplift rate. Whereas the southern segment of the Central Cordillera shows substantially higher local relief and mostly well graded river profiles consistent with longer term uplift-rate stability. We also identify several areas of major drainage reorganization, including captures and divide migrations that are supported by our erosion and incision rate estimates.

The petroleum explorations become chiefly conspicuous. The Amazonas Basin can be subdivided into two principal morpho- structural units, which differ clearly by their stratigraphical and structural conditions. There are: I—The Lower, Middle and Upper Amazonas Trough in Brazil, and II—The Subandean Zone of Upper Amazonas. *) Note: The redaction ventures to point out, that editing the above work of Prof.

The investor fervently hopes that the Market Cap miner will be successful with the drill bit and that the share price subsequently $5.75 million reflects that success. Given the risk, the investment reward has to be substantial. Ideally, the investor is looking for a “ten-bagger”, and these do Average Daily Volume occur. A double from 10 cents to 20 cents a share sounds good in terms of 50-day: 74,100 percentage gain, but an investor/speculator wants more than that, preferably 200-day: 39,300 the stock reaching a dollar. Year-End March 31 Antioquia Gold Inc. (“Antioquia” or the “Company”), in our opinion, has a legitimate chance of achieving that sought-after ten-bagger.

  • A Partial Glossary of Spanish Geological Terms Exclusive of Most Cognates
    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY A Partial Glossary of Spanish Geological Terms Exclusive of Most Cognates by Keith R. Long Open-File Report 91-0579 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government. 1991 Preface In recent years, almost all countries in Latin America have adopted democratic political systems and liberal economic policies. The resulting favorable investment climate has spurred a new wave of North American investment in Latin American mineral resources and has improved cooperation between geoscience organizations on both continents. The U.S. Geological Survey (USGS) has responded to the new situation through cooperative mineral resource investigations with a number of countries in Latin America. These activities are now being coordinated by the USGS's Center for Inter-American Mineral Resource Investigations (CIMRI), recently established in Tucson, Arizona. In the course of CIMRI's work, we have found a need for a compilation of Spanish geological and mining terminology that goes beyond the few Spanish-English geological dictionaries available. Even geologists who are fluent in Spanish often encounter local terminology oijerga that is unfamiliar. These terms, which have grown out of five centuries of mining tradition in Latin America, and frequently draw on native languages, usually cannot be found in standard dictionaries. There are, of course, many geological terms which can be recognized even by geologists who speak little or no Spanish.

[email protected], [email protected], [email protected], [email protected], [email protected] 2 Universidad Nacional Autónoma de México, Centro de Geociencias, Campus Juriquilla, Blvd. Juriquilla No. 3001, 76230, Querétaro, México. [email protected] * Corresponding author: [email protected] ABSTRACT. The Antioquia batholith represents the magmatic record of the interaction between the Farallón and Caribbean plates with the NW part of the South American Plate during the Meso-Cenozoic. Several authors have reported zircon U-Pb ages and whole rock geochemistry in order to constrain the crystallization history of this batholith and its formation conditions. The present work aims to gather the existing data with new data obtained from the Ovejas batholith and La Unión stock, both genetically related to the main intrusion. Gathering our new data with information obtained in previous works, we conclude that the Antioquia batholith was constructed by successive pulses from ca. 97 to 58 Ma in an arc-related setting. The initial pulses are related to syn-collisional tectonics, during the early interaction between the Farallón plate and NW South America.
