Description:
Abstract:
Locations of known phosphate occurrences in this area, with geologic units in which such deposits may occur.
Purpose:
These data were assembled and edited to contribute to a mineral resource assessment of Afghanistan and adjacent countries. Consequently the site descriptions are not intended to document fine details of the workings at each occurrence location.

Data_Set_Credit:
Greta J. Orris compiled the data in an Excel spreadsheet format. Pamela Dunlap imported the data into an Esri file geodatabase feature class, standardized the data, made minor revisions, and wrote the metadata. Rearrangement of these data on the web site mrdata.usgs.gov was carried out by Peter Schweitzer.
Data_Quality_Information:
Logical_Consistency_Report:
Geologic units included here were drawn from 1:1,000,000 scale maps, and include those whose lithologies indicate they could be host rocks for phosphate deposits. Deposits and potential host lithologies in countries neigboring Afghanistan were included in this study because the lithologic units are likely to extend into Afghanistan or similar units may be present there.
Completeness_Report:
Within Afghanistan, only a handful of known occurrences and reports indicate the presence of phosphate in sediments and carbonatite. Of these, only the Khanneshin carbonatite has been studied extensively.
Lineage:
Process_Step:
Process_Description:
Information on phosphate occurrences and deposits was obtained from published literature. Distribution and extent of geologic units that might host phosphate deposits was drawn from geologic maps of 1:1,000,000 scale.
