粤北石人嶂莲花山隐伏花岗岩侵入体岩浆动力学特征分析
Magmatic Dynamics Characteristics of Concealed Granite Intrusions in Lianhuashan,Shirenzhang, Northern Guangdong Province
摘要
Abstract
Based on deposit geology,structural geology and fluid mechanics,we have analyzed the tungsten-bearing granite intrusions in the Shire-nzhang mine, northern Guangdong Province. We have calculated the temperatures and pressures, magma density, magma viscosity, and magma cooling velocity during the formation of rock mass and described the magmatic dynamic features,and found the change law of the density with the temperature. The results indicate that it is favorable for energy accumulation during the process of emplacement,and the slow cooling permitted sufficient time to ensure any crystal growth. Then we made a discussion on granite emplacement mechanism and elucidated the relationship between the emplacement and tungsten mineralization. This study provides a hydrodynamic basis for understanding the genesis of the deposit,and offers scientific evidence for development and utilization of the mine.关键词
