A型花岗岩的标志和判别——兼答汪洋等对“A型花岗岩的实质是什么”的质疑
The criteria and discrimination for A-type granites: A reply to the question put forward by Wang Yang and some other persons for “A-type granite: what is the essence?”
摘要
Abstract
A-type granites are silicon-, alkali-rich, water-poor granitoids, characterized geochemically by poor Al, Sr, Eu, Ba, Ti and P. A-type granites are formed under low pressure and high temperature conditions, and have no choice for source rocks. The essence of the A-type (or the Nanling type) granites lies in the melting of granitic magma under low pressure and their generation mainly in the tectonic setting of crustal extension and thinning. The several "A-type granites" abroad cited by Wang Yang et al. are actually mostly outside the category of A-type granites and were not formed under low pressure conditions.关键词
