Location: Delger, Gobi-Altai
“Nuurst Khotgor – 15372X” Licensed area is located 65km northwest from Govi-Altai soum center, 15km south from Delger soum, 750km southwest from Ulaanbaatar city.
The geography of this region is typically desert landshaft that belongs to the gobi-steppe region and by geography shape and surface topology belongs to the small hills and undulating land. Generally this South Gobi of Altai region with huge desert valleys and mountains that covered by dark and burnt colored surface shows up the special geography type of dry region. South Gobi of Altai region is with extreme continental conditions, dry climate, low precipitation and spring comes early, winter tends to have strong winds occasionally wind storms can cause periods of brown outs. The weather conditions are extremely dry and hot with a rainfall level of circa 64-70mm per annum. There are telecommunications, hospital services, public schools, petrol stations, power stations, hotels and shops located in Gobi-Altai soum center. The site is reachable by ground transportation, population is very sparse and infrastructure is poor developed.
In 1876-1877 Potanin.G.N was noted Aj Bogd’s mountain consist of bright-pink colored granite between Tagna and Tenger mountais trip.
In 1896 Klements.D.A and others were explored to the Western Mongolia and studied glacial deposits that not good developed at there and it depends on high elevation of area. Also were identified Altai Mountains of South and West Gobi were consisting of Paleozoic sedimentary and metamorphic rocks.
Between 1940-1945 years were collected many informations about plants of Mongolian.
Also between 1941-1944 years Murzaev.E.M were explored general exploration of geography study and identified climate, fauna, flora, geographical and paleogeographical conditions of Ikh Nuuruudiin Khotgor Area.
In 1951 Sinitsin.B.M were identified and classified Gobi-Tyanshan, Eastern Dornot, Baruun Khuurai and Bayan-Undur formations are differentiated by classification. The formation of Baruun Khuurai zone consists of sediments of Lower-Middle Paleozoic geosynclinals structure.
In 1956, 1:1,000,000 scale exploration mapping was completed in the region from the Alag Lake to the northwest of the Altai range and the Khangai range and established that this region belongs to the Caledon structure formation platforms. In result of this exploration work were determinied significiant mineralizations of iron, copper, chromite-titanomagnetite, chrysoliteasbest and platinium.
Also 1:1,000,000 scale geological mapping was completed by Russian and Mongolian geologists in the south western part of the Mongol Altai region between 1958 and 1959.
Between 1988-1990 years the tectonic range formation and geological developments were studied and completed 1:200,000 scale geological mapping including the Baruun Khuurai geosynclinals structure of this region and these studies supplemented the study on Mesozoic and Cainozoic aged rock strata and biostratigraphy.
In 1995-1998 Mongolian geologist were completed the 1:200,000 scale mineralization and prediction-metallogenic map of Mongol Altai region.
Quaternary deposit / QIV /
Pebble, rock debris, boulder, different sized sandy loam, mild clay of alluvial, prolluvial, delluvial, eolian and lacustrine deposits were developed on the mountain slope, foot, cone and cone of dejection. Thickness of sediment is irregular and 0.5-20-30m.
Upper Quaternary sediment / QIII /
In this licensed area were developed intermountain basins glacial, fluvial and lacustrine deposits. Compositions of these alluvial and prolluvial deposits are boulder, clump, pebble, rock debris, calciferous sand, sandstone, clay, mild clay and foot and flood plain deposits are also concerned.
Medium-Upper Quaternary sediment / QII-III /
In this licensed area were developed foot, flood plain, fluvial, lacustrine and eolian deposits that differentiated by origins. Compositions of these alluvial and prolluvial deposits are boulder, rock debris, oolite, medium rounded and badly differentiated pebble, gravel, slanting bedded sand and sandy loam, mild clay with calciferous cement. Stratigraphical classifications were identified on the fauna and flora. Thicknesses of sediments are foot-5m, food plain-10-15m and fluvial 10-15m.
Neogene’s sediment, Miocene, Oshin’s series/ N1os /
In the entire study area Oshin’s sediment of Miocene, Neogene were occurred 25 percent of whole area and covered by Quaternary sediments. Components of these sediments are different colours of clay, pebble, rock debris, conglomerate, conglomerate breccia, slanting bedded sandstone, siltstone and amygdaloidal bazalt with olivine and calcite.
Late Jurassic sediment, Toromkhon’s series / J3tr /
Composition of Late Jurassic, Toromkhon series deposits are red colored conglomerate, conglomerate breccias, gravelstone, calciferous sandstone, siltstone and claystone.
Previous research results established the possibility of a coal layer in the Mesozoic and Cainozoic terrigenous strata. The South Khangai coal depression zone suggests widespread coal throughout the southwest region especially in Gobi-Altai province. The results of 1:200 000 scale geological mapping and geological tectonic structure of the area provide a strong basis for future exploration for coal in this area.
