新疆康古尔地区花岗岩地质、地球化学特征及地质意义

GEOLOGICAL AND GEOCHEMICAL FEATURES OF THE GRANITES AND ITS GEOLOGICAL SIGNIFICANCE IN KANG -GUR OF NORTH TIANSHAN,XINJIANG

通过对康古尔地区Ⅰ,Ⅱ号花岗岩体地质特征、岩石化学特征、氧同位素及稀土元素地球化学的综合研究,确定了这两个岩体均为“S”型花岗岩。确定了Ⅰ号岩体岩浆的流动方向。对花岗岩稀土元素配分型式的解释做了一些探讨。

The comprehensive study of geology, petrochemistry, geochemistry of oxygen isotope and rare earth elements,revealed that both No. 1 and No. 2 rock bodies were of S - type granite,and determined the fluid direction magma of No. 1 rock body. Some explanations of the partiton pattern of rare earth elements were also given.
