| 摘 要： | 位于华北克拉通南缘的洛南-卢氏地区出露大量与成矿密切相关的中酸性小侵入体,主要岩性包括石英闪长岩和钾长花岗斑岩,其中大部分是该区矽卡岩型和斑岩型铁-铜-钼-铅锌多金属矿床的成矿母岩,但迄今为止对这些岩体的侵位时代及岩浆活动构造背景的研究还很薄弱.文章利用激光剥蚀电感耦合等离子体质谱法对该区典型侵入岩(夜长坪、柳关、后瑶...

| Abstract: | Granitoid intrusions,which are widely distributed in Luonan-Lushi area on the southern margin of the North China Craton,consist mostly of K-feldspar granite porphyry and quartz diorite and are closely related to lots of porphyry and skarn Fe-Cu-Mo-Pb-Zn polymetallic deposits in this area.Nevertheless,precise numerical constraints on the emplacement ages of these intrusions,which are of importance in the understanding of the tectonic setting of regional magmatism,are very insufficient.In this paper,the autho... |
