摘 要: | 对查干呼绍地区中生代侵入岩的时空分布、岩石学、岩石化学、地球化学及同位素年代特征等进行了较详细的对比和研究,认为该时代侵入岩具有完全不同的演化特征,其原因是地壳成熟度及长期活动的地台北缘断裂制约着本区断裂两侧中生代侵入岩的发展和演化。

Evolutionary Characteristics of Mesozoic MagmaDistributing on Bothside of large Regional Rupture in Chaganhushao Area, Central Inner Mongolia |

Abstract: | By the detailed comparison and research on the characteristics of spacetime distributing, petrology, petrochemistry, geochemistry and isotope age, Mesozoic intrusive rocks in Chaganhushao area, Inner Mongolia distributing on bothside of large regional rupture have the different evolutionary characteristic. The reason is the mature degree of crust and the long active north marginal rupture controlled the development and evolvement of the intrusive rocks. |

Keywords: | Mesozoic magma evolvement central Inner Mongolia. |
