主 题:fault structure lead-zinc deposit profile inversion Qingchengzi Liaoning
摘 要:Qingchengzi ore concentration area in Liao-Ji rift is an important lead-zinc ore area of China,and the deep prospecting in this area has great *** on the spatial occurrence of ore bodies the Pb-Zn deposit can be divided into three types:layered,vein-shaped and *** deep geological conditions in this area are deduced by analyzing the tectonic evolution process and rock mass gravity *** tectonic evolution of Liao-Ji rift can be divided into three stages:Paleoproterozoic extension period,Mesoproterozoic compression period and Mesozoic reactivation *** magmatic activities in the Indosinian epoch led to the distribution pattern of the present *** to the gravity inversion,Shuangdinggou-and Xinling rock masses on the north and south sides of the mining area are connected in the *** connected rock body might be distributed in the entire mining *** rock mass may be a branch extending from Shuangdinggou rock mass along the northeast trending fault,the connected rocks provide magmatic hydrothermal fluid for the final,folds and faults result in different types of ore body shapes.
