摘要
沉积地球化学是一门沉积学与地球化学相互渗透、相互结合而产生的新兴边缘学科。是以沉积物和沉积岩为研究对象,由于不同时期,不同地段的物理化学条件不同,所形成的岩石有不同的元素组合,因此可以通过研究其在沉积——成岩过程中所含元素及稳定同位素的迁移、聚集与分布规律来判断、恢复沉积古环境。本文总结了对沉积环境有指示意义的常见沉积地球化学特征。
Sedimentary Geochemistry is a new marginal subject which is derived from combining of Sedimentology and Geochemistry.Its object of study is sedimentary deposit and sedimentary rock.We can use the study of elements and stable isotope＇s disciplinarian of transference、 aggregation and distribution during diagenetic process to recover sedimentary environment in that vary chemical and physical conditions have different element combination.In this paper the common characteristics of Sedimentary Geochemistry for indicating sedimentary environment are provided.
