中文摘要: 通天庙花岗岩体位于南岭成矿带的香花岭锡多金属矿田西南部,通过对其开展地球化学分析研究表明,主量元素具有高硅、富铝、富碱、贫铁、贫镁、贫钛,高铝饱和指数的特点,稀土元素总量高,轻重稀土无明显分馏,Eu具极强的负异常,微量元素具有富高场强元素,大离子亲石元素,高10 000×Ga/Al,亏损Sr、Ba、Ti元素的特征,均与典型的A型花岗岩相似,说明通天庙花岗岩体应属于过铝质钙碱性-高钾钙碱性A型花岗岩,形成于造山后拉伸环境下,这一认识为了解通天庙花岗岩体成因及构造演化提供了理论依据。

Abstract:The Tongtianmiao granites are located in the southwestern part of Xianghualing tin-polymetallic ore field. Through a series of geochemical analysis,the major elements of the Tongtianmiao show high SiO2, rich in Al2O3 and Alkali, deleption of Fe,Mg,Ti, and high A/CNK;The rare earth elements show high ∑REE,no fractionation between light and heavy rare earth elements,and very strong negative Eu anomalies;the trace elements are rich in HFSE such as Nb、Ta、Zr、Hf、Th、U and LILE such as Cs、Rb, high 10000×Ga/Al, depletion of Sr、Ba and Ti, which are similar to the A-type granite. In conclusion, the Tongtianmiao granite are peraluminous calc-alkaline - high-potassium calc-alkalin A-type granite which is formed in the post-orogenic extensional environment, which provides the theoretical basis for the understanding of the genesis and tectonic evolution of the Tongtianmiao granite.
