熔融包体是岩浆在结晶过程中被矿物包裹而形成的,具有“天然岩浆”之称。花岗岩中熔融包体的研究,对于探讨花岗岩的成因,了解成岩条件都具有重要的意义。诸广岩体是华南大型花岗岩基之一。对于诸广岩体的成因,目前众说纷纭,主要有重熔观点和南大地质系的花岗岩化观点。花岗岩中熔融包体的研究,对以上两种看法的区别,可以提供一定的依据。本文想通过对诸广岩体中段燕山期花岗岩中熔融、气液包体特征的研究及形成温度的则定,对诸广岩体的成因和成岩条件作一初步的探讨。
Molten inclusions are formed by mineral inclusions in the crystallization process of magma, which is called “natural magma”. The study of the melting inclusions in granite is of great significance to the study of the genesis of granite and the understanding of diagenesis conditions. Zhu Guang rock is one of the large granite base in South China. For the causes of ZhuGuang rock mass, there are different opinions at present, mainly including remelting point of view and granite point of view of Nantong geological department. The study of the melt inclusions in granite can provide a basis for the difference between the above two views. Based on the study of melting and gas-liquid inclusions in the Yanshanian granite in the middle segment of Zhuguang Rock Mass and the tectonic setting of temperature, this article attempts to make a preliminary study of the genesis and diagenesis conditions of ZhuGuang massif.
