Figure 14.—Close-up photograph of the hydrothermally brecciated, quartz-veined Dusar gossan. Figure 5.—Photograph of the silver, gold, and copper mineralization in the synorogenic veins of the "northern occurrence." Some veins, such as these, exhibit open-face vugs with late-stage textures such as coarsely crystalline quartz and drusy quartz, and contain abundant malachitecarbonate-limonite fillings, which suggest a latestage hydrothermal event. Figure 10.—Photograph of boxwork veining within massive gossanous material of the Dusar "iron hat." Figure 11.—Photograph of steeply-dipping, banded veins underlying the massive Dusar gossan. Individual bands, which are centimeters thick, consist of Fe-rich chert and limonite. Steeply-dipping banded layers suggest outward mineral precipitation toward the wall rock of iron-rich siliceous fluids along near vertical conduits. The pen is shown for scale. Figure 7.—Aerial view looking northwest along the Dussar gossan. Figure 12.—The Dusar gossan is not known for its enrichment in copper, silver, and gold, although some samples do contain copper concentrations as high as 0.1 weight percent. Note the peacock coloration in this sample indicative of the presence of bornite (Cu5FeS4). Figure 13.—Hand specimen of the intensely silicified, hematitic gossan with siliceous vein fragments. Figure 2.—View looking southwest of the white, quartz-carbonate, polymetallic, synorogenic veins of the "northern occurrence." The distance from the foreground to the farthest hill is approximately 500 meters. Figure 16.—Photograph of amphibolite of unit Kdg north of the Dusar gossan. Figure 4.—Soviet quarry within the polymetallic, synorogenic veins of the "northern occurrence." Note the copper staining within the veins and vein margins. The veins occur as stacked, sheeted swarms over a strike length of 1 kilometer and a thickness of over 200 meters. Individual veins range in thickness from 10 centimeters to over 1 meter. Figure 15.—Photograph of quartz keratophyre of the volcanic rocks (Jvp) beneath the Dusar gossan. Figure 3.—Close-up photograph of a polymetallic, synorogenic vein of the "northern occurrence." Note the sharp contact between vein and phyllitic host rock (Jvp), alteration of the immediate wall rock, and the fragments of phyllite incorporated within the vein. The sharpness of the contact, the presence of metamorphic rock fragments within the vein, and the lack of melting texture suggest a modestly warm (below melting temperature) synmetamorphic origin for the veins. Figure 18.—Uranium-lead (U-Pb) concordia diagram of zircon analyses from quartz keratophyre (unit Jvp) at the Dusar gossan locality. Fifteen concordant SHRIMP analyses define a crystallization age of 177.5±3.5 Ma for the quartz keratophyre, indicating an Early Jurassic age. Numbers on the regression line and on the vertical axis of the inset are in millions of years before present (Ma, mega-annum). Additional abbreviations: MSWD, mean square weighted deviation; n, number of analyses considered in the weighted mean age; SHRIMP, sensitive high resolution ion microprobe. Figure 17.—Cathodoluminescence (CL) images of dated zircon from the Dusar quartz keratophyre sample RT-10D-1D (unit Jvp). The clear, short, prismatic zircons of igneous origin show relatively high CL brightness, with both well-developed sector and oscillatory zoning. The yellow circles refer to the SHRIMP spot analyses where crystallization ages were determined for each zircon. Results for spots 6, 7, 8, and 9 are identified on figure 18. Figure 8.—Aerial view of the Dusar gossan looking south. The lightcolored rocks in the foreground are zones of extensive "buck quartz" veining in greenschist-grade phyllite and quartz keratophyre. The rustcolored shapes outline the area of extensive gossan development. The largest exposure of the gossan is approximately 100 meters long and 40 meters wide.

Units ages for Jls and Jvp were reassigned as Early Jurassic, from the Soviet's Lower Cretaceous age assignment, as a result of our zircon SHRIMP analyses of quartz keratophyre of unit Jvp, which yielded a crystallization age of 177.5±3.5 Ma (see figs. 17 and 18).] Alluvial and proluvial deposits (upper Quaternary)—Flood plain and low terrace deposits of unconsolidated gravel, sand, silt, and clay Talus (upper Quaternary to Neogene)—Alluvial and proluvial deposits of weakly cemented sandstone; with clay, loam, sandy loam, boulders, and pebbles. Thickness of the unit is approximately 70-100 meters (m) Felsic volcanic rocks (Early Jurassic)—Quartz keratophyre, quartz-feldspar porphyry, quartz porphyry, and "aphyric" porphyries; with rare interbeds and (or) lenses of massive, fine-grained limestone, and jasperoids. The unit is characterized by high-grade metamorphic modifications resulting in schistose and phyllitic porphyritic rocks, and rare quartz-chlorite and chlorite-sericite shale and slate. Thickness of the unit is 2,000 m or greater Limestone (Early Jurassic?)—Fine-grained limestone with lesser black calcareous shale, calcareous argillaceous shale, sandstone, and conglomerate. The unit is characterized by high-grade schistosity and chloritization resulting in carbonate-chlorite and chlorite slate. Thickness of the unit ranges from 0.05-0.1 m to 250-350 m EXPLANATION OF MAP SYMBOLS Contact—Dashed where inferred (dashed in cross section and map B only) Fault—Dashed where inferred; dotted where concealed Fault zone Intense schistosity Crushed rock Folds—Showing trace of axial surface, direction of dip of limbs where known, and direction of plunge Anticline Lines and symbols Structural lines—Shown in cross section and map B only Boundary of "iron hat" rocks under loose deposits Boundary of oxidation zone—Shown in cross section only Quartz vein Strike and dip of bedding—Dip values shown where known Trench, number from Tarasenko and others (1973) Exploration shaft, number from Tarasenko and others (1973) Borehole, number from Tarasenko and others (1973) Significant minerals occurences Copper Iron sulfide Primary mineralization halos—Number refers to concentration in weight percent Copper Lead Zinc Tin Molybdenum Arsenic Secondary mineralization halos—Number refers to concentration in weight percent Copper Lead Zinc Tin Primary occurrence—Number refers to concentration in weight percent Copper Lead Zinc Tin Molybdenum INTRODUCTION The geologic maps and cross sections presented in this report are redrafted and modified versions of the Geologic map and map of useful minerals of the Dusar area (scale 1:50,000) and Geologic sketch map of the Dusar and Namak-sory ore occurrences (scale 1:10,000), located in the Herat Province, Afghanistan. The original maps and cross sections are contained in unpublished Soviet report no. 0290 (Tarasenko and others, 1973) prepared in cooperation with the Ministry of Mines and Industries of the Royal Government of Afghanistan, in Kabul during 1973 under contract no. 50728. The redrafted 1:50,000 scale map consists of portions of quadrangle map sheets 414-A-I, 414-A-II, 414-A-III, 414-A-IV, 414-C-I, and 414-C-II shown on an index map that can be found on the Soviet original by Tarasenko and others (1973). Presentation of the 1:50,000-and 1:10,000-scale maps herein is very similar to their presentation in the original report in which there is noticeable difference between the two maps in their expression of the surficial geology; no corrections to the surficial geology depicted on the maps have been made due to many uncertainties regarding preparation of the original maps. The redrafted maps and cross sections (modified from Tarasenko and others, 1973) illustrate the geological structure and mineral occurrences of the Dusar copper-gold-silver-lead-zinc prospect area of western Afghanistan, located within the Dusar-Shaida copper and tin area of interest (AOI), Herat Province, Afghanistan. The location of AOIs of non-fuel mineral resources within Afghanistan were first described and defined by Peters and others (2007) and (2011), and most recently the location of several new AOIs have been defined by DeWitt and others (2015). The location of the Dusar-Shaida copper and tin AOI is shown on the index map provided on this map sheet. Mineralization in the Dusar area is hosted within Early Jurassic to Early Cretaceous stratified volcanic and sedimentary rocks associated with numerous diabase and gabbro-diabase intrusive bodies (unit Kdg), and is generally near a major northeast-trending system of faults and quartz veins. Host rocks consist of quartz keratophyre and quartz-feldspar porphyry (unit Jvp), with layers of schist, phyllite, and quartz-chlorite and chlorite-sericite slate; and limestone and shale, with schist and carbonate-chlorite and chlorite slate (unit Jls). Known mineralization includes an extensive quartz vein system, shown on the map as the "northern occurrence" (map A), as well as the Dusar and Namak-sory gossan zones, interpreted to have formed from remnant pyrite mineralization. The veins of the northern occurrence and their altered host rocks are known to contain anomalous to economic concentrations of precious and base metals, with concentrations locally in excess of 2 parts per million (ppm) gold (Au), 100 ppm silver (Ag), 5 percent copper (Cu), and 1 percent lead (Pb). These veins occur in swarms, and are hosted along structures that are approximately concordant with the plane of the metamorphic fabric. The veins consist mostly of quartz, with minor carbonate and sulfide minerals, and display weak alteration halos along their margins. The gossans are locally anomalous in these metals, but their size and extent makes them attractive exploration targets for potential massive sulfide mineralization. The Dusar gossan is a zone of massive, ochreous, and siliceous limonitic rock, approximately 2,200 meters long, 30 to 250 meters wide, and 2.0 to 7.2 meters thick. Diamond drilling below the Dusar gossan intersected a siliceous, sericitic, and limonitic rock underlain by quartz keratophyre with abundant disseminated pyrite. Mineralized sections grade 0.06 weight percent copper and up to 0.05 weight percent zinc (Abdullah and others, 1977). The Namak-sory gossan zone, contains a similar deposit with anomalous concentrations of Cu, Zn, and Au. The redrafted maps and cross sections reproduce the topology of rock units, contacts, and faults of the original Soviet maps and cross sections, and include minor modifications based on examination of the originals and observations made during two brief field visits by USGS staff in August, 2010, and June, 2013. Further, the original Russian terminology and rock classifications have been translated into modern English geologic usage as literally as possible without changing any genetic or process-oriented implications in the original rock unit descriptions. Some original map features were not reproduced and some may be misidentified due to the poor quality of the original maps. Rock unit symbols have been modified from the originals for simplification, and the age designations for units Jls and Jvp were reassigned as Early Jurassic, from the original Lower Cretaceous assignment, as a result of zircon SHRIMP analyses of quartz keratophyre of unit Jvp (177.5±3.5 Ma; see figs. 17 and 18). Further, rock unit colors on the maps and cross sections differ from the colors shown on the original versions, and were selected according to the color and pattern scheme of the Commission for the Geological Map of the World (CGMW) (://www..org). Elevations on the cross sections are derived and slightly modified from the original Soviet cross sections and may not match the Global Digital Elevation Model (GDEM) topography used on the maps of this report; topographic elevations on the original Soviet cross sections and maps are uncertain. Hydrography derived from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) has not been included on the redrafted versions of the maps because of a poor fit with alluvial deposits shown on the original Soviet maps (appendixes 2 and 5 of Tarasenko and others, 1973). Photographs were taken by Robert D. Tucker of the U.S. Geological Survey during visits in August, 2010, and June, 2013 (figs. 1 to 16). The photograph locations (where applicable) are shown on the maps by the "site of photograph" symbol keyed to the figure number.
