河南省华北型寒武系

河南省华北型寒武系可划分为3统9组26个化石带。华北地台早寒武世辛集期海侵来自扬子浅海北部。华北海与扬子海中、晚寒武纪时彼此分离。通过与澳大利亚、北美、西伯利亚等地的寒武系对比,认为在寒武纪华北海与澳大利亚海相连,与北美海相通,与西伯利亚海先远而后近。上述海域都位于赤道附近的远洋区。

THE CAMBRIAN OF NORTH CHINA TYPE IN HENAN PROVINCE

The Cambrian of North China type in Henan province may be divided into three series, nine formations and 26 fossil zones. The Xinji-aged （Early Cambrian） sea transgression in the North China platform originated from the northern part of the Yangtze shallow sea. There was appreciable difference in MidLate Cambrian biotas between the North China Sea and the Yangtze Sea. It is inferred that the North China plate was separated from the Yangtze plate in the Cambrian. Through the stratigraphical correlation with the Cambrian in Australia, North America and Siberia, it is considered that the North China Sea was linked with the Australian Sea, connected with the North American Sea and first departed far from and then neared the Siserian Sea in Cambrian time. The above-mentioned seas were all located in the oceanic region near the equator.
