元素地球化学在准东沉积古环境研究中的应用
Application of Element Geochemistry in the Research of Zhundong Deposit Palaeoenvironment
摘要:
元素地球化学在划分海陆相地层、分析物源区岩石成分、恢复沉积的古气候条件，以及利用微量元素对不含生物化石的“亚地层”进行地层对比，特别是确定沉积水介质地球化学环境、划分地球化学相上取得了较满意的效果。运用烃源岩岩性、岩相、沉积特征反映沉积古环境，烃源岩元素地球化学特征反映的水介质沉积环境，烃源岩生物标记化合物反映的水介质沉积环境，几方面相互印证提高研究的可信度。
Abstract:
The application of element geochemistry is efficient in classifying marine and land facies, analyz-ing rock components in provenance, recovering palaeoclimatic condition where deposit occurred and correlating intrastratigraphy which didn’t contain fossil organism by using trace element, especially in identifying geochemical environment of sedimentary water medium. Lithology of hydrocarbon source rock, rock facies and deposit characteristic are used to reflect sedimentary palaeoclimate, element geochemistry characteristic of hydrocarbon source rock is applied to reflect sedimentary condition of water medium, and biomarker of source rock is studied to reflect sedimentary condition of water medium, which ensured the accuracy of the conclusion.
