摘要:

本文剖析了滇黔桂南盘江地区晚古生代一系列古碳酸盐台地中的一个小型台地—桂西北隆或台地。隆或地区石炭系沉积相可分为台地、台缘斜坡及海槽三大类型。根据沉积相的空间展布,隆或古台地在石炭纪时为一个孤立的碳酸盐台地,周围被海槽围限。古断裂活动造成了槽台相间的古地貌格局,也是碳酸盐台地演化的古构造背景。

Abstract:

A small one of series of Palaeozoic carbonate platforms in the joint of Yunnan, Guizhou and Guangxi provinces, Longhuo ancient platform, has been dissected in detail. Carboniferous sedimentary facies of Longhuo area can be divided into three major types; carbonate platform facies, platform margin slope facies arid trough facies. According to space distribution of the sedimentary facies, Longhuo ancient platform was an isolated one, surrounded with troughs in the Carboniferous period, Ancient faulting caused' the palaeomorphologic pattern of platforms alternating with troughs, and were also the palaeotectonic background of Longhuo ancient platform evolution.
