引言以副矿物电气石命名的花岗岩,早就见诸于众多地质文献。花岗岩常见副矿物达数十种之多,用其命名,难免有失之于滥之嫌。然而,读者会发现,本文论述的电气石花岗岩,是一类颇具特色的含锡花岗岩。章振根首创三 B 型花岗岩的称谓,其中一 B,即挥发分硼。Pollard 等认为,每个含锡省或省内锡成矿区有富 F 和富 B 环境,有相对富 F 或富 B 的岩浆。他们同建立锡石- 硅酸盐矿床类型的苏联学者一样,似乎意识到了什么,却还不曾把握住什么。
Introduction Granite, named after the accessory mineral tourmaline, has long been found in many geological literature. Granite common deputy minerals up to dozens of species, with its name, it is inevitable to miss too suspicion. However, readers will find that the tourmaline granite discussed in this article is a distinctive class of tin-bearing granite. Zhang Zhengen first three B-type granite title, one of the B, that is volatile boron. According to Pollard et al., Each tin-bearing province or province has a rich F and B-rich environment with relatively rich F or B-rich magma. Like the Soviet scholars who established the cassiterite-silicate deposit type, they seem to be aware of what they have not yet grasped.
