| 摘 要： | 格尔柯金矿 (即大水金矿 )是产于西秦岭南带西倾山—迭山逆冲褶断带南缘的特大型金矿。矿床控矿地质条件为构造单元界断裂带、深源浅成花岗闪长斑岩小侵入体、下三叠统马热松多组 (T1m)碳酸盐岩沉积建造 ,与金矿关系密切的矿化蚀变有硅化、赤铁矿化、褐铁矿化和方解石化 ;矿床成因类型为层控—热水溶滤构造蚀变岩型。

| Abstract: | Gerke gold ore deposit (Dashui gold ore deposit) is an extraordinary one,and it occurred in south border of Xiqingshan-Dieshan thrust zone in south district of West Qinling mountians. The ore-control geologic setting boundary fault zone of tectonic elements, small intrusives what belong in plutonic-hypabyssal granodioritic porphyry, lower Triassic Maresongduo Formation (T 1 m ) which is carbonate sedimentary formation, and silication, hematitization, limonitization and calcitization are closely related to gold mineralization; ore genesis is stratabound-hydrothermal leached structural alteration. |
