碳酸盐岩台地构造控制因素及源储组合模式

Tectonic Control Factors and Source-Reservoir Assemblage Mode of Carbonate Platform

以国内外各盆地的碳酸盐岩台地实例为出发点,基于前人研究基础,将碳酸盐岩台地分为镶边大陆架型、陆架内台地和孤立台地。前者的碳酸盐一般沉积在台地边缘,后者台地向海一侧可以过渡到碳酸盐岩海相沉积,被动大陆边缘的孤立台地,碳酸盐岩台地相一般发育在碎屑岩、蒸发岩以及底部浅滩火山之上。另外,碳酸盐台地的形成受多种构造因素控制,而拉伸作用形成下的台地又可以根据运动学分为基底断块台地、旋转断块台地、生长断块台地。另外,小克拉通构造活动以及古地形地貌对于台地的发育也有重要的影响。源储组合可以分为常规组合、侧变型组合、顶生型组合、自生、自储、自盖型组合等。

Carbonate platform may be divided into rimmed continental shelf platform, inner shelf platform and isolated platform. The formation of carbonate platform is controlled by such factors as tectonism, landform and topography. The carbonate platform resulting from stretching may be subdivided into basement fault block platform, rotation block platform and growth fault block platform. The source-reservoir assemblage may be divided into conventional array, lateral variant array, acrogenesis array and regional assemblage rock, reservoir and caprock.
