绪论 热液矿床中金属及伴生元素的来源,长期来一直是地质学家们争论的课题之一。自阿格利科拉(AgricoIa)时期以来,认为有四种可能性,列述如下: (1) 元素来自地球深部。地幔常被认为是可能的来源,甚至更深的部位也曾有人提及。 (2) 元素来自结晶的岩浆体。一些研究者倾向于基性岩浆,另一些人倾向于形成花岗闪长岩和花岗岩的酸性岩浆。如果这些岩浆岩出露于地表或者能在 Introduction The origin of metals and associated elements in hydrothermal deposits has long been a topic of debate among geologists. Since the Agricole period, four possibilities have been identified as follows: (1) The elements come from deep in the earth. The mantle is often considered as a possible source, and even deeper parts have been mentioned. (2) Elements come from crystalline magma. Some researchers prefer mafic magmas, while others tend to form acidic magmas of granodiorites and granites. If these magmatic rocks are exposed or can be on the surface
