摘要
稳定同位素测年信息,是深部构造、成矿作用和地层年代学的重要依据。笔者从壳下深断裂带、基性超基性岩带特征、层控矿床中古老矿石铅模式年龄和湖南最老的地层等方面,探讨了湖南的前元古宙结晶基底和地质发展史。
The information of stable isotopic aging is the important basis for the deep structures, mineralization and chronostratigraphy. The authors discussed the crystalline base of the pre-proterozoic in Hunan and the developing history from following aspects: the characteristics of deep fractures and basicultrabasic rocks, Pb-isotopic type age of ore in stratabound deposits and the oldest stratum etc.
