| 摘 要： | 本文描述了梵净山区新元古界下部鸟叶组与甲路组之间的喀斯特不整合的空间分布、地质特征，从而进一步确认了它的存在；指出该不整合是格林威尔碰撞造山之后强烈隆升的产物，代表了Rodinia超大陆在新元古代裂解前地壳经历的隆起并遭受剥蚀侵蚀的历程，从而对研究该时期地层的空间变异、沉积环境，特别是探讨Rodinia超大陆岩相演化都具有重要的科学意义。

| Abstract: | It is made a characterization in this paper that spatial distribution and geologic feature of the karst unconformity of the lower Neoproterozoic between Wuye Formation and Jialu Formation in the area of Fanjingshan Mountain, further acknowledging its presence. The unconformity is in consideration the products of intensely upheaval subsequent to Greenwill collision orogeny, it stands for a course that Rodinia supercontinental crust have underwent the uplift and denudation before the Neoproterozoic breakup, and consequently possesses of significant scientific implication for the studies of spatial variation and sedimentary environment at that time, especially petrographic evolution of the Rodinia super-continent. |
