郯庐断裂带两侧华北型下寒武统生物岩相带的错移

DISPLACEMENT OF THE NORTHERN—CHINA TYPE LOWER CAMBRIAN BIOLITHOFACIES BELTS ON SIDES OF THE TANCHENG—LUJIANG FAULT ZONE

摘要:

根据对郯庐断裂带两侧华北型滨浅海相氧化环境碎屑岩—碳酸盐建造下寒武统的展布、下寒武统各组沉积范围和沉积起始层位的迁移规律以及各标志岩性段生物岩相带及其界线的对比分析,论证了该断裂带的左行平移性质,确定其错移距离为500km。

Abstract:

This paper demonstrates a sinistral displacement character of the Tancheng—Lujiang fault zone and determines that the displacement distance is up to 500km. The conclusion is based on the sedimentary zoning of the Northern—China type Lower Cambrian, the migration regularity of the sedimentary range and the initial formations and the correlation of the biolithofacies zones of marked lithological members on the sides of the Taneheng—Lujiang Fault Zone.
