Application of energy geochemistry in the establishment of the heirarchical units of granitic rocks

摘要: 岩浆的侵位和演化过程不仅仅表现为物质上的演化趋势 ,而且也是能量的释放和转移过程。以海洋山花岗岩体为例 ,通过对岩体岩石能量的计算 ,初步探讨了岩石能量地球化学在花岗岩体岩石谱系单位建立中的应用 ,并通过圆石山岩体和栗木岩体对该方法进行了验证。在同源岩浆演化的条件下 ,无论岩石结构是由粗粒到细粒或者是由细粒到粗粒演化 ,岩石的能量从早期侵位单元到晚期侵位单元是逐渐增大的。Abstract: The emplacement and evolution of magma are not only a trend of material evolution but also a process of energy release and transfer. Through the calculation of the energy of granitic rocks of the Haiyangshan granite body, the authors discuss the application of rock energy geochemistry in the establishment of the heirarchical units of granitic rocks and check and verify this method through the examples of the Yuanshishan rock body and Limu rock body. Under the conditions of comagmatic, no matter whether the rock texture evolves from coarse to fine grains or from fine to coarse grains, the energy of rocks increases progressively from the early stage emplacement units to late stage emplacement units.
