海洋碳酸盐沉积相模式

MARINE CARBONATE DEPOSITIONAL FACIES MODELS

本文在评述国内外有关碳酸盐相模式研究基础上提出,海洋碳酸盐沉积相模式研究已摆脱了60—70年代的静态的束缚而进入了一种动态研究阶段并强调碳酸盐缓坡(ramp)的重要性。同时,文中还对台地和缓坡的定义重新进行了厘定,并提出碳酸盐相模式的端元类型概念及其分类。此外,建隆的形成、海平面变化和大地构造背景对其有着不可忽视的控制作用,而碳酸盐相模式又控制了储集层的分布型式。

The marine carbonate facies models have broken away from static models in the 1960's—1970's and are coming into a dynamic ones,in which carbonate ramp plays an important role. The definitions of carbonate platform and ramp are revised and the carbonate element models are put forward in this paper. The formation of buildup,eustatic change and geotectonic settings control essentially transformation of carbonate facies model from one to another and the modesl control the distribution of resevoirs.
