1965年以来,英国等国的地质学家先后在秘鲁安第斯山脉和东南亚锡矿带对大量花岗岩体进行了区域性研究,打破了长期以来人们对花岗岩只注意岩性描述和物质成分鉴别的传统,着手于同源岩浆岩套或序列的划分,从区域范围内发现各个侵入体是按一定规律组合成数量不多的岩性—岩浆单元,这些单元在岩基内部构成固定的侵入顺序,可 Since 1965, geologists from Britain and other countries conducted a series of regional studies on a large number of granite bodies in the Peruvian Andes and the Southeast Asian tin belt, breaking the tradition that the granite only paid attention to lithology description and material composition identification for a long time. Starting from the same magmatic rock sets or sequence division, from the region found that each intrusion body is grouped into a small number of lithology - magmatic units according to certain rules, these units constitute a fixed invasion order within the rock foundation,
