1) Zhongtiao paleo rift
中条古裂谷
2) Zhongtiao rift
中条裂谷
1.
The author inversed the stepwise evolution of Zhongtiao rift by analyzing Precambrain sedimentary formation,magma formation and tectonic form of the Zhongtiaoshan-Wangwushan region and discussed the perfect mineralization conditions of the Wangwushan region formed in the evolution of the Zhongtiao rift and regional crust.
对中条—王屋山地区前寒武纪沉积建造、岩浆建造、构造形态的分析后,反演出中条裂谷的递进演化过程,认为王屋山地区在中条裂谷和区域地壳的演化过程中形成了极为有利的成矿条件:①形成多层含矿建造;②通达地幔的深大断裂提供了丰富的矿源和成矿空间;③频繁的岩浆活动补充了矿质并提供了成矿热能;④剥离断层系统进一步提供了扩容空间;⑤以活化转移为主要机制的强烈变形变质作用对已形成的含矿建造(矿源层)进行改造。
4) Liaodong paleorift
辽东古裂谷
5) Panxi paleorift
攀西古裂谷
1.
Zircon SHRIMP U-Pb dating was performed on alkali feldspar-quartz syenite and arfvedsonite alkali granite in the Cida alkali complex in the Dechang area, in the Panxi paleorift.
对产于攀西古裂谷带内的德昌地区茨达碱性杂岩体中的碱长石英正长岩和钠铁闪石碱性花岗岩进行了锆石SHRIMP U-Pb年龄测定,年龄结果分别为221Ma±6Ma和225Ma±2Ma,表明该碱性岩的结晶年龄或成岩年龄相当于晚三叠世,同时暗示攀西古裂谷的张裂时间为三叠纪。

Yele granite exposed in Yele,Mianning,middle sector of west margin of the Yangtze landmass, is a S type granite It gives an isopotic age value of 350±19Ma,so that it was emplaced in the Early Carboniferous and was a product in prerifting anticline uplift stage of the Panxi paleorift This result fills in the gaps in the Early Carboniferous magmatism in this regio
在岩体中获 350± 19Ma的年龄值 ,表明其侵位时代为早石炭世 ,为攀西古裂谷孕育时期的裂前台背斜隆起阶段的产物。
