热分析和流体动力学分析表明,由于许多钙碱性花岗岩类的粘度和密度差跨越于其所设想的典型范围,因此岩墙式上升乃是大体积花岗岩类熔体穿越陆壳而转移的一个可行的机制。我们的计算结果表明,一个粘度约为10’Pa·s的岩浆与地壳之间的密度差为200物矿的花岗岩类熔体,可以在
Thermal analysis and hydrodynamic analysis show that the dikes in the granite-like granulite are due to the transgression of large-volume granitoids across the continental crust due to the difference in viscosity and density of many calc-alkaline granites crossing their typical range Feasible mechanism. Our calculations show that a density difference of magma between the crust and a magma of about 10’Pa · s is a granite-like melt of 200 minerals,
