本文应用岩相古地理理论对南盘江地区的一些地质构造进行了再认识:由于区内南盘江壳断裂及百色壳断裂的存在,引起了中三叠世岩相的剧烈变化;尼拉背斜不是一个以构造应力为主形成的背斜构遣,而是一个由台地边缘生物礁(滩)相沉积隆起形成的两侧反倾斜的沉积构造;对永和断层引起的局部地段两盘地层错移方向与应力分析的错移方向相反的原因进行了解释。
In this paper, some geological tectonics in Nanpanjiang area are re-recognized by using lithofacies palaeogeography theory. Because of the existence of Nanpanjiang fault and Baise shell fault in the area, the lithofacies parallels the dramatic changes of the Middle Triassic facies. The anticline is not an anticline inclined structure formed mainly by tectonic stress but an anti-tilting sedimentary structure on both sides formed by the sedimentary uplift of the reef (beach) facies on the margin of the platform. Two strata of the local section caused by the Yonghe fault The reason why the direction of the misalignment is opposite to that of the stress analysis is explained.
