| This map was produced from several larger digital               datasets. Topography was derived from Shuttle Radar Topography Mission (SRTM) 85-meter               digital data. Gaps in the original dataset were filled with data digitized from contours on               1:200,000-scale Soviet General Staff Sheets (1978–1997). Contours were generated by               cubic convolution averaged over four pixels using TNTmips1 surface-modeling               capabilities. Cultural data were extracted from files downloaded from the Afghanistan Information Management 		                Service (AIMS) Web site (http://www.aims.org.af). The AIMS files were originally derived               from maps produced by the Afghanistan Geodesy and Cartography Head Office (AGCHO). Geologic               data and the international boundary of Afghanistan were taken directly from Abdullah and               Chmyriov (1977).

It is the primary intent of the U.S. Geological Survey (USGS) to present the                   geologic data in a useful format while making them publicly available. These data                   represent the state of geologic mapping in Afghanistan as of 2005, although the                   original map was released in the late 1970s (Abdullah and Chmyriov, 1977). The USGS has                   made no attempt to modify original geologic map-unit boundaries and faults; however,                   modifications to map-unit symbology, and minor modifications to map-unit descriptions,                   have been made to clarify lithostratigraphy and to modernize terminology. The generation                   of a Correlation of Map Units (CMU) diagram required interpretation of the original data,                   because no CMU diagram was presented by Abdullah and Chmyriov (1977).

This map is part of a series that includes a geologic map, a topographic map, a Landsat                natural-color-image map, and a Landsat false-color-image map for the USGS/AGS (Afghan                Geological Survey) quadrangles shown on the index map. The maps for any given quadrangle                have the same open-file report (OFR) number but a different letter suffix, namely, -A, -B, -C, and -D                 for the geologic, topographic, Landsat natural-color, and Landsat false-color maps,                 respectively. The OFR numbers range in sequence from 1092 to 1123. The present map series is to be followed by a second series, in which the                 geology is reinterpreted on the basis of analysis of remote-sensing data, limited                 fieldwork, and library research. The second series is to be produced by the USGS in                 cooperation with the AGS and AGCHO.
