云南腾冲北部华力西期印支期花岗岩

Variscan and Indosinian granites in northern Tengchong, Yunnan

阐述了云南腾冲北部华力西期花岗斑岩（磨石岭单元）和印支期花岗岩（和尚塘单元）的地质特征、岩石特征、地球化学特征和同位素特征。资料和数据表明，前者为板内花岗岩，后者属同碰撞花岗岩，两者的产出时代恰好与滇西古特提斯洋闭合、中特提斯洋张开的演化过程相吻合。

This paper deals with the geological, petrological, geochemical and isotope geochemical characteristics of Variscan granite porphyry (Moshiling unit) and Indosinian granite (Heshangtang unit). Material and data indicate that the former is intraplate granite, while the latter syncollision granite. The ages of the two types of granite just coincide with the closing fo the Paleo Tethys of western Yunnan and opening of the Mid Tethys.
