This shapefile contains points that describe the location of rock samples (core samples and outcrop samples) collected in Afghanistan and adjacent areas, and the results of organic geochemical analysis.

This shapefile contains polygons that describe the spatial extent of tectonic zones in northern Afghanistan and adjacent areas.

This shapefile includes polygons that describe U.S. Geological Survey defined geologic provinces that encompass northern Afghanistan.

This shapefile contains points that describe the location of hydrocarbon exploration and production wells drilled in Afghanistan; and hyperlinks to scanned images of well logs that can be viewed in an ArcReader project.

This shapefile includes polygons and regions that describe U.S. Geological Survey defined petroleum resource Assessment Units of northern Afghanistan. Each assessment unit is defined as a mapable volume of rock within a total petroleum system that encompasses fields (discovered and undiscovered) that share similar geologic traits and socio-economic factors. The fields inside an assessment are a sufficiently homogenous population that a single methodology of resource assessment is applicable. Assessment units are described by U.S. Geological Survey research scientists on the basis of available geologic knowledge, exploration and production histories, and extensive literature searches. Assessment units are identified with a numeric code derived from the numeric code of the World Geologic Provinces defined by the U.S. Geological Survey World Petroleum Assessment 2000.

This shapefile contains polylines that describe the location of seismic lines in northern Afghanistan.

This shapefile includes polygons that describe U.S. Geological Survey delineated Total Petroleum Systems of northern Afghanistan. Each petroleum system is defined as a mappable entity encompassing genetically related petroleum that occurs in seeps, shows and accumulations (discovered and undiscovered) that have been generated by a pod, or by closely related pods, of mature source rock, together with the essential mappable geologic elements (source, reservoir, seal and overburden rocks) that control fundamental processes of generation, migration, entrapment and preservation of petroleum. Total petroleum systems are described by U.S. Geological Survey research scientists on the basis of exploration and production histories, and extensive literature searches. Total petroleum systems are identified with a numeric code derived from the numeric code of the World Geologic Provinces defined by the U.S. Geological Survey World Energy Project.

This dataset accompanies the proposed publication, 'Geochronology and geochemistry of igneous and metasedimentary rocks of northeast Afghanistan: A refinement of the timing and origin of crustal terranes', which focuses on refining the geochronology and geochemistry of these rocks during multiple time periods of accretion, regional metamorphism, and magmatic activity. The analyses were performed from September 2006 to August 2014.

This shapefile contains polylines (isopachs) that describe the thickness of Jurassic age evaporite facies (Gaurdak formation) in the Afghan-Tajik and Amu Darya basins
