Abstract:

白云鄂博群尖山组H?4岩性段石英砂岩中的碎屑锆石年龄纪录了华北克拉通北缘两期重要的构造岩浆事件,一组年龄集中在新太古代―古元古代初期(2379~2596Ma),另一组年龄集中在古元古代晚期(1761~1946Ma),该结果与白云鄂博地区基底岩石的锆石年龄相吻合。白云鄂博群沉积碳酸盐岩的全岩??207?Pb??206?Pb等时线年龄1649±45Ma,代表了白云鄂博群的沉积时代。白云鄂博地区沉积灰岩、白云岩与含矿白云岩的Pb同位素组成存在非常大的差异,在Pb同位素组成和构造图解中,含矿白云岩都集中在地幔演化线附近,靠近亏损地幔端元\[(??206?Pb/??204?Pb)??i?=15.04~16.49,(??207?Pb/??204?Pb)??i?=15.17~15.28,(??208?Pb/??204?Pb)??i?=31.20~36.40\],而白云鄂博群中的灰岩、白云岩则位于造山带演化线附近,靠近深海沉积物端元\[(??206?Pb/??204?Pb)??i?=17.28~19.35,(??207?Pb/???204?Pb?)??i?=15.47~15.69,(??208?Pb/??204?Pb)??i?=36.62~37.12\]。
