渭北西部中奥陶统碳酸盐岩地球化学特征及古环境恢复
Geochemical Characteristics of Middle-ordovician Series Carbonatite and Restoration of Paleoenvironment in West Weibei
摘要
Abstract
This paper studied the paleoenvironment in the region of Majiagou, through the test analysis carbon-oxy-gen isotopes and microelements of middle-ordovician Majiagou carbonatite in west Weibei, as well as through the e-valuation and adjustments towards the primitiveness of the carbon-oxygen isotopes.And the analysis was respective-ly done qualitatively and quantitatively on the salinity, temperature, climate and redox-property of the paleo-sedi-mentary environment.During quantitative analysis, formula method and least-squares method had been adopted, and their differences were compared.The results of the research based on the combination of these two methods can effectively reflect the information data of paleoenvironment, such as climate and temperature, etc.关键词
