Abstract

A film of pyrites was discovered on the interface of Lower Sinian Sidingshan Formation and Fengtai conglomerate, at Sishilichangshan Mountains in the south margin of the North China Block. The macroscopic, microscopic and geochemical studies of the film of pyrite reveal that the interface is a breakup unconformity. The discovery and determination of the breakup unconformity provides substantive proof for studying geological response of North China Block at the interval of Rodinia supercontinent breakup, and offers important tectonic background for studying the genesis of Fengtai conglomerate and its equivalence.
- Huoqiu movement,
- breakup unconformity,
- north China block
