试论花岗质深成岩体的复合定位机制及定位空间问题

大陆地壳中巨量花岗岩体的定位机制及定位空间是一个长期急论的问题，已提出十余种机制，但都困难以解决定位空间面引起争议，近年来，人们认识到岩体定位及获取空间是多种机制共存的复合定位机制，这是今后需进一步研究的新课题，笔者提出的复合定位机制可概括为主动膨胀，构造扩展，岩浆侵吞作用３个基本端元机制的构成的复合，可用三角图解表述，并以具体研究实例进行了论述。

Multiple Emplacement Mechanism and Space of Granitoid Plutons

The problem of emplacement mechanism and space of tremendous amounts of granitoid plu-tons in the continental crust has long been disputed. More than ten mechanisms have been proposed, but all of them can hardly solve the space problem, so are disputed. Recently, it has been recognized that emplacement of plutons and their space making are a multiple mechanism consisting of many mechanisms. This is a new subject which needs to be studied further. This paper discusses the multipe mechanism on the basis of three basic mechanism elements, i. e. : forceful expansion, tectonic extension and magmatic swallowing. A triangle diagram is designed to describe them, and some case studies are given.
