| 摘 要： | 首次从同位素、稀土元素及微量元素和岩石化学等方面,对内蒙古赤峰地区红花沟钾长花岗岩的地球化学特征、成岩时代及岩体成因等进行了系统的研究。该岩体属壳幔型同熔花岗岩,其岩石化学成分与辽东太古宙钾长花岗岩相近,分异指数平均值85.35;稀土配分模式与元占宙都山岩体相似。Rb-Sr,K-Ar和Pb同位素特征表明,该岩体是1800Ma时地壳增长事件的产物,1100Ma时曾发生再次活动。

| Abstract: | The geochemical characteristics, petrogenetic age and genesis of thekaligranite in Honghuagou gold deposit are systematically studied for thefirst time by the methods of isotope, REE, trace element geochemistry andpetrochemisty. The kaligranite has the general geochemical characteristicsof granitoids associated with gold deposits. Its petrocbemical compositionsare similar to those of Archean kaligranites in East Liaoning province.D. I is 85.35. Its REE distribution pattern is similar to that of DushanProterozoic granite in East Hebei provincc. The Rb-Sr, K-Ar and Pbisotopic features show that the kaligranite is the product of the crustenlarge event at about 1800Ma and is reactivated at abont 1100Ma. Thekaligranite belongs Lo crust-mantle type synthesis granite. |
