Název v původním jazyce

Prospection for gold and new occurrences of gold-bearing mineralization in the eastern Mongolian Altay

Popis výsledku v původním jazyce

New occurrences of Au, Cu, Zn and (Ba)-As-Sb-Hg mineralizations were discovered by geological mapping 1:50,000 and regional geochemical prospection in the eastern Mongolian Altay. The panned-heavy mineral survey was combined with the dry stream-sedimentgeochemistry and lithogeochemical sampling. The morphology and composition of placer gold grains were studied in order to estimate the type of primary source and his distance from the placer. The ascertained gold-bearig mineralizations are represented namely by Au and Au-(Ag) quartz veins in Neoproterozoic basic metavolcanic rocks and in Permian volcanic rocks. Gold locally accompanies vein?disseminated base metal mineralization in some Proterozoic and Lower Palaeozoic formations. A prospective occurrence of clastic gold in Mesozoic conglomerates and sandstones was found at the northern edge of the Zamtyn Nuruu Mts. around the Samoandamba Uul. There is a distinct contrast in quantity of ore indices between the two terranes forming the s
