ColombiaMap – a GIS database for Colombia, available in MapInfo or in ArcGIS format

ColombiaMap is a GIS database that assembles and displays information pertaining to the geology and metallic mineral resources of Colombia.

ColombiaMap modules, designed to be used together, include Geography, Geology, TS Units, Prospects, Radiometric Dates and Land Status.

For a detailed description of the database and for pricing information, click on: Colombia Readme or contact RdC.

The Geography module includes shaded relief, bathymetry and digital elevation models (DEM) along with major infrastructure (towns, cities, highways, political boundaries).

The Geology module provides an up-to-date geologic map (published in 2015) in vector format. It includes the Geography module and is suitable for those who are interested only in the published geology of Colombia.

The TS Units module, which is built on and includes the Geology and Geography modules, provides a tectono-stratigraphic interpretation based on published references. TS Units provides the base for a metallogenic map of Colombia.

The Radiometric Dates module compiles 4500 published radiometric dates attributed with sample number, sample location, host rock, radiometric date, mineral or material dated, uncertainty and a reference to the published source of the date.

The Prospect module, which includes the Geography, Geology, TS Units and Radiometric Dates modules, plot 2100 known metallic mineral mines and prospects. Each mineral occurrence is linked to current information on past production, reserves and resources and references to the literature. The Prospect module can be used to plot a metallogenic map, assess prospectivity and guide exploration.

The Land Status module, which includes Geography, locates over 12000 metallic mineral concessions (attributed with ownership and contract date) and plots the location of national parks, forest reserves and other areas of restricted mineral entry.

References provides a copy, in pdf format, of over 160 publications used to compile the ColombiaMap database.

Plots provides up-to-date metallogenic and land status maps as high resolution tiff images.

 

The Prospect module can be used to:

  • Review resource and production information for individual mineral occurrences.
  • Find references to the literature with more information on specific properties.
  • Evaluate prospectivity by using the distribution of the tectono-stratigraphic terrane that hosts a given deposit type.
  • Answer specific queries, e.g. “Locate and identify all deposits with over 500,000 ounces gold.”
  • Select properties for evaluation and possible acquisition.
  • Design exploration programs to focus on a particular tectono-stratigraphic unit.
  • Click on Prospect DEMO to see how the Prospect module works.

 

The Land Status module can be used to;

  • Identify areas already covered by exploration or extraction concessions.
  • Identify the owner of individual concessions, the contract date and the expiration date.
  • Check for nearby parks, national forests, or other areas of restricted mineral entry.
  • Answer specific queries such as “Locate all concessions held by Minera Occidente, S.A.”
  • Click on Land Status DEMO to see how the land status module works.

Multi-element geochemical data for Colombia, in MapInfo or in ArcGIS format.

Colombian government agencies and mineral exploration companies have, over the years, carried out many regional geochemical sampling surveys. Survey results were difficult to obtain, confidential to the sponsoring company or, in the case of government-sponsored surveys, available only via purchase and/or license agreement with the SGC (Servicio Geológico Colombiano).

In 2015, the SGC released a compilation of multielement geochemical data (150 surveys) to the public. This database, which is available from the SGC at no cost, consists of multielement data for 168,656 samples, including 72,536 stream sediment samples. Unfortunately, the database is difficult to use, incomplete, and riddled with errors. Recursos del Caribe, S.A. (RdC) took the raw analytical data, converted text to numeric fields as appropriate, found and corrected 772 duplicate entries and 702,330 data entry errors and added 54,553 missing sample locations. The result, after a total of 31,538,671 edits, is a user-friendly GIS database that can be applied with confidence.
