南京孔山剖面早二叠世冰川旋回期内氧碳同位素演化特征及其环境意义
CHARACTERISTIC OF OXYGEN-CARBON ISOTOPES AND ITS ENVIRON-MENTAL SIGNIFICANCE OF LOWER PERMIAN CARBONATE ROCK IN KONGSHAN SECTION,NANJING,JIANGSU
摘要
Abstract
Taken from Nanjing Kongshan section in series,samples of LowerPermian carbonate rock are studied isotopically in this paper.Researches,are related with sea level change,are also completed by studying the variation of oxygen-carbon isotopes of the section.The result shows that value of oxygen isotope is controlled mainly by the balance between “Global Ice Effect” and regional mixed freshwater effect in seashore.Although the characteristic of oxygen isotope can not be illustrated by an extant model designed for pelagic sediment,it can reflect the change of original environment faithfully.Value of carbon isotope is not a linear function of ancient sea level change.The most important factors,which control the values of carbon isotope,are the embedding velocity of organic carbon and relative environment of reduction-oxidation.关键词
