摘要

摘要: 报道了北京西山下苇甸剖面中寒武统碳、氧同位素特征,并基于下苇甸剖面中寒武统沉积特征和碳、氧同位素地球化学指标进行层序地层划分,将该地区层序发育置于深时格架中,并与全球海平面升降相联系。研究表明,北京西山中寒武统可划分为3个二级层序和8个三级层序,每个三级层序对应于全球海平面变化事件。该时期主要发育的沉积相类型包括蒸发潮坪相、低能内台地相、高能外台地相和低能开阔海相。中寒武世华北地台构造背景稳定且处于温暖的气候背景下,绝对海平面变化为层序发育主控因素。

Abstract: The C and O isotopes of the Middle Cambrian of the Xiaweidian Section in the Beijing Western Mountain areas is for the first time reported by our study. In order to study the evolutionary history of the Middle Cambrian of Xiaweidian Section and its controlling factors, sedimentary characteristics and stable isotopes are applied to establish stratigraphic sequences based on the chronology framework established by eustatic sea level changes. Three 2nd order and eight 3rd order sequences are recognized. The sedimentary facies observed include evaporated tidal flat, low-energy inner platform, high-energy outer platform and low-energy shallow sea. The eustatic sea-level change is the primary driving factor which controls the sequence development in a tectonic stable and warm climate background as such.
