花岗岩类岩浆作用与若干主要金属成矿作用的成因联系是一个很重要的研究课题。为研究这个问题,多年来多沿用以岩石命名为目的的岩石化学和定量矿物分类。近年来,人们逐渐认识到岩石化学即岩石主要元素成分所能提供的岩石成因信息有限,而岩石中的痕量元素和同位素成分模型可以确切表征岩浆源的特点,能够提供更详细的成因信息。因而有不少人开 The genetic relationship between granitic magmatism and several metallogenic processes is a very important research topic. To study this issue, rock chemistry and quantitative mineral classification for the purpose of rock naming have been followed for many years. In recent years, people gradually come to realize that rock chemistry is a rock that has limited information on the genesis of the rocks. The trace elements and isotopic compositions in rocks can characterize magma sources and provide more detailed genetic information. So there are many people to open
