摘要
综述了环斑花岩岗研究的新进展。环斑花岗岩既可以出现于从太古代到显生宙的各个地质时期 ,也可以产生于造山带中。这些不同时代、不同构造环境特别是造山带环斑花岗岩与经典的元古代克拉通上的环斑花岗岩在岩石学、地球化学和产生的构造动力学背景上有何异同是今后需要研究的问题。
The major features for rapakivi granites are rapakivi texture, Proterozoic age and anorogenic setting. Recent studies show, however, that rapakivi granites can be formed in age from Archaean to Phanerozoic and can even occur in orogen. The difference between the typical Proterozoic rapakivi granites and the other rapakivi granites of various ages and tectonic settings in petrology, geochemistry and tectonic dynamic is a problem needing to be further studied. This also brings about new problems on the definition of rapakivi granite and the differences between rapakivi granites and rapakivi like granites.
