摘要
Abstract
Since the conception of A-type granite came into being 30 years ago,there has been a great change in definition and recognition of the rock type,structural setting,magmatic source and origin.Presently,A-type granite appears more inclusive,a number of so-called A-type granites differ greatly from the original definition and there seems to be an inevitable trend that all granites formed in extensional environment will be called A-type granites.Based on data research and comparative study,it is suggested that A-type granite determination should be strictly in line with its original definition with emphasis laid on the 3A features.Only on this basis can its magmatic origin and structural implications be discussed in a correct way.关键词
