摘要
本文是通过对四平市山门银矿区侵入岩的实地研究而撰写的。研究结果表明,区内侵入岩为印支—燕山期岩浆活动的产物。为同源演化的多次活动的岩浆系列,并属壳幔过渡的同熔型。从岩浆活动的时间上、空间上以及物质来源等诸方面均与银矿化有着极为密切的关系。
Through on-the-spots study of the Shanmen Ag ore area,Siping, the result suggests that intrusive rock belongs to the Indosinian-Yanshanian period, resulting from multiple activities of the magmatic series cognate evolution, and referring to syntectic type of the crust-mantle transition. Magmatic activity is closely related to the silver minerlization in the time and space, sources of materials and so on.
