华北地层大区下寒武统特征岩性组合对比与岩石地层划分

Combination Contrast of Characteristic Lithology and Divission of Litnologic Stratigraphic Units in Lower Cambrian in Stratigraphic Region in Northern China

摘要:

根据华北地层大区下寒武统引用地层单位的特征岩性组合构成及其与鲁中特征岩性组合序列的对比，按照“两灰两红”的沉积格局，建立完整连续的岩石地层单位序列：雨台山组—李官组—余粮村组—馒头组。山西及以西各地的霍山组与馒头组的底部层位相当。

Abstract:

Based on the contrast between characteristic lithology combination in lower Cambrian in stratigraphic region in North China and characteristic lithology combination sequences in Luzhong area, according to the sedimentary framework named as “two gray and two red”, continuous succession of lithostragraphic units have been established as follows: Yutaishan formation— Liguan formation—Yuliangcun formation—Mantou formation. The bottom layers of Huoshan formation in Shanxi province and other areas in western Shanxi province and Mantou formation are quite the same.
