摘　　要：在二叠纪的南盘江盆地中发育着许多大大小小的孤立碳酸盐台地,高龙碳酸盐孤立台地是其中一个小型的孤立碳酸盐台地。在该孤立台地上,马平组珊瑚生物礁和茅口组海绵生物礁呈一种滑动面的形式接触,意味着高龙孤立台地具有极为独特的生长发育历史。横穿高龙孤立台地的区域性同生断裂———八渡—那棉断裂,把高龙孤立台地分割为南北两个不同的块体,该断层的南翼和北翼形成差异极大的地层系统。该同生断裂以及与其倾向相反的滑动面的共同作用使高龙孤立台地呈现出一个"地垒"的形态。构造作用以及沉积作用等方面呈现出独特的现象,表明高龙孤立台地的生长过程可能代表了一个特别的孤立碳酸盐台地的生长发育模式。In Permian period,there were a variety of isolated carbonate platforms,large and small,were grown in the Nanpanjiang Basin,among which the Gaolong isolated platform was a small one.In the Gaolong platform,both the coral reef of the Carboniferous Maping Fm.and the sponge reef of the Permian Maokou Fm.were developed in a contact-relationship of a sliding plane,which means a particular history of the birth,evolution and demise of the Gaolong isolated platform.A large regional fault that is Badu-Namian fault crosses through this platform,and divides it into two stratigraphic blocks that are marked by different stratigraphic system.This fault was a contemporaneous fault in Permian.Controlled by the contemporaneous sliding plane as well as the contemporaneous fault,the Gaolong isolated platform was formed in the shape of'horst'in Permian.A lot of respects that include tectonic action as well as sedimentation show many interesting phenomena,which indicate that the sedimentary model of the Gaolong isolated platform could represent a particular model of birth,evolution,demise of a isolated carbonate platform.
