梵净山区白云母花岗岩特征及其意义

Significance and Characteristic of Muscovite Granite in Fanjingshan Area

梵净山地区是中国南方出露中元古代地层的地区之一,尤其是其发育在中元古代末、新元古代初进入了陆内造山的发展、演化历程,形成了淡色花岗岩组合为代表的构造热事件,它反映了本区武陵造山运动的结束,是研究中国南方Rodinia超大陆发展、演化的极佳地区,梵净山群白云母花岗岩特征及性质的研究,具有十分重要的地球科学意义。

Fanjingshan is one of the areas where the mesoproterozoic layer exposed in the south China, especially the developing and evaluation process interior orogeny in the end of Meso Proterozoic and early Neo Proterozoic, formed tectono thermal events which the ochric granite association as the example, it reflected the end of Wulinshan orogeny in this area and it＇ s the very place to study the development and evaluation of Rodinia supercontinent in China. The study of the characteristic and property of muscovite granite in Fanjingshan has very important geoscientific indicatorificance.
