| 摘 要： | 南岭中段以花山一姑婆山为起点,发育一条南西-北东向的燕山早期富钨锡A型花岗岩带,其中姑婆山岩体以其富含暗色微粒包体( MME)而闻名.为寻找岩浆混合的矿物学证据并探索基性岩浆与钨锡富集的关系,我们使用电子探针对姑婆山岩体花岗岩和暗色包体中的副矿物进行了系统的成分分析和对比.研究首次确认了暗色包体的铁镁矿物解理中含有岩浆...

| Abstract: | In the middle part of Nanling Range there is an early Yanshanian(Jurassic) A-type granite belt.The Guposhan granite batholith is well known by its mafic microgranular enclaves(MME) .In order to study the mineralogical evidence of magma mixing and the relationship between basic magma and tin-mineralization,we studied and compared the compositions of accessory minerals in the granite and MME by using elecron microprobe.We firstly confirmed the appearance of subhedral cassiterite of magmatic origin in cleavage... |
