GEOLOGICAL CHARACTERISTICS AND PROSPECTING DIRECTIONS OF DONGPING GOLD DEPOSIT IN LIAONING PROVINCE
-
Abstract
The Dongping gold deposit is located in the Lingyuan-Fuxin gold metallogenic belt of western Liaoning Province, with gold ore/mineralized bodies mainly occurred in the silicified tectonic breccia, silicified rhyolite and silicified rhyolitic breccia lava. The ores are dominated by native gold and electrum, among which the former accounts for 80% and the latter 20%. The IP intermediate gradient and drilling results show that the ore bodies are mainly controlled by the NNW-trending structure with the gold ore/mineralized bodies constrained in the F2 structure altered zone of high resistance-low polarizability. By soil geochemical survey, 22 comprehensive anomalies are delineated and several concealed gold ore/mineralized bodies are found in the I-4 anomaly area by drilling verification. Based on a detailed study of the geological characteristics, through comparison with the adjacent Zhaojiagou gold deposit, the preliminary conclusion is that the Dongping gold deposit is genetically epithermal type. It is also believed that the pyritization, strong silicification and carbonatization in the NNW-trending structure altered zone are significant mineralization and alteration, and the high resistance-low polarizability and Au soil geochemical comprehensive anomaly zone are key prospecting directions.
