内蒙古红山子复式岩体地质时代的厘定及其地质意义
|
摘要
通过岩相学研究和LA-ICP-MS锆石U-Pb测年,对红山子岩体的主要侵入期次和侵入岩形成时代进行了厘定,明确了红山子岩体为复式岩体并探讨了其地质意义。岩相学研究表明,红山子复式岩体由粗粒碱长花岗岩、斑状黑云母花岗岩、细粒黑云母碱长花岗岩和花岗斑岩等组成; LA-ICP-MS锆石U-Pb测年结果显示:粗粒碱长花岗岩的年龄为153. 6±1. 2 Ma,斑状黑云母花岗岩年龄为151. 4±1. 1 Ma,与周边火山盆地赋矿火山岩的年龄一致,属晚侏罗世早期;细粒黑云母碱长花岗岩的年龄为131. 5±1. 8 Ma,花岗斑岩年龄为133. 3±1. 4 Ma,与侵入红山子盆地的花岗斑岩的年龄一致,属早白垩世早期。因此,红山子岩体是由燕山期2个相隔20 Ma的不同期次侵入体组成的复式岩体。研究表明,红山子铀矿床赋存在早白垩世早期花岗斑岩与晚侏罗世火山岩的内、外接触带中,暗示复式岩体早白垩世早期细粒黑云母花岗岩、花岗斑岩与晚侏罗世粗粒碱长花岗岩、斑状黑云母花岗岩的内、外接触带是有利的找矿部位,并得到了铀矿勘查实践的初步证实。
Through the study of lithology and LA-ICP-MS zircon U-Pb dating, the main invasion period of Hongshanzi rock and the age of intrusive rock formation were determined. It is clear that Hongshanzi rock is a complex rock. The authors discussed its geological significance. The study of petrography indicates that Hongshanzi complex rock is composed of middle coarse grained alkali feldspar granite, porphyritic biotite granite, finebiotite granite and granite porphyry. The LA-ICP-MS zircon U-Pb dating results show that the age is 153. 6 ± 1. 2 Ma for middle coarse grained alkali feldspar granite, and 151. 4 ± 1. 1 Ma for porphyritic biotite granite, which are in accordance with the data obtained around the ore-bearing volcanic basin, and belong to the early period of Late Jurassic. The age of finebiotite granite is 131. 5 ± 1. 8 Ma and that of granite porphyry is 133. 3 ± 1. 4 Ma, consistent with the age of the granite porphyry which invaded Hongshanzi Basin and belonging to the early period of Early Cretaceous. Therefore,Hongshanzi Yanshanian complex rock is composed of two different periods in Yanshanian epoch, whose time span is20 Ma. Studies show that the Hongshanzi uranium ore deposit occurs along the contact zone of granite porphyry of early Early Cretaceous and volcanic rocks of Late Jurassic, which indicates that the contact zone between complex rock of middle coarse grained alkali feldspar granite, porphyritic biotite granite and fine biotite granite and granite porphyry is the best place for mineral exploration, and this conclusion was verified by the uranium ore exploration.
