对四平市山门银矿中生代侵入岩成因及与成矿关系的再认识

A NEW UNDERSTANDING ON THE MESOZOIC INTRUSIVE ROCK GENESIS AND ITS RELATIONSHIP WITH METALLOGY IN THE SHANMEN SILVER DEPOSIT,SIPING AREA

山门银矿区出露的中生代侵入岩是一套由基性岩、中性岩、酸性岩组成的复式侵入体。具有规模大、侵入期次多、演化时间长的特点。在成因上属于同熔型花岗岩系列，在物质来源上属于壳幔混合型，岩浆活动具明显的多阶段性；在时间上、空间上及物质来源上与成矿有着极为密切的关系。在综合分析的基础上，建立了“岩浆活动与成矿的综合模式”。

The outcropped Mesozoic intrusive rock is a composite intrusion which consists of basic,intermediate and acid rocks,characterized by the large scale,multiphase intrusion,and with long evolution.Originally,it belongs to the syntectic granite series,and about the source,belongs to mixed type of crust mantle having obviously multistage magmatic activities.There is an extremely close relationships between time,space,mass source and mineralization.On the basis of comprehensive analysis,the magmatic activity and comprehensive metallogenic model is set up.
