    Abstract:

    Based on the study of the geological evolution, metallogenetical characteristics in central-northern Daxinganling belt, and the distribution characteristics of the ore deposits at the adjacent areas in Mongolia and Russia, the geological units and metallogenetic zones are divided, the main types of the ore deposits and metallogenetical ages are summed up. The direction of ore prospecting in the belt is proposed. Daxinganling metallogenetical belt is divided into three geological units of third-order, i.e. Eerguna block, Elunchun hercynian fold belt and Dongwuqi early-hercynian fold belt, and subdivided into 14 geological units of fourth-order. The types of ore deposits include skarn, porphyry, hydrothermal, VMS, magmatic differentiation, placer and greisen, the hydrothermal ore deposits canbe subdivided into 6 secondary types. The porphyry-type and hydrothermal-tye ore deposits are the most important. The ore deposits mainly distribute in northeastern direction as well as with a north-western array. According to their space distribution and the characters of the main ore-controlling tectonics, Daxinganling metallogenetic belt is divided into two third-order metallogenetic zones: Deerbugan and Dongwuqi-Xinganl and 13 fourth-order metallogenetic enrichment regions. On time scale, the formation of ore deposits in the belt has been last from early Paleozoic to late Mesozoic era, the later era is main age. The mineralization of various types of ore deposit is quite different. The formation of the single type of porphyry deposits may last from early last from early Paleozoic to late Mesozoic, but other types of ore deposits mainly formed during Yanshanian period. It is implying that the ore-prospecting for skarn and hydrothermal ore deposits should focused on the region of Yanshannian magmatic-tectonic activity developed, for the porphyry deposits, both the Paleozoic and the Mesozoic magmatic-tectonic areas should be stressed.
