The continental mantle geochemical characteristics and crust-mantle evolution in the west of Yangtze Plate was discussed through the study of some within-plate basic ultrabasic rocks from Lower Proterozoic to Later Paleozoic in this paper.

本文通过对扬子板块西部从早元古代至晚古生代不同时期的多个板内基性超基性岩的地质地球化学研究，探讨了扬子板块西部大陆地幔的地球化学特征及壳幔演化机制。

The Northern Uplift of the Tarim Basin had undergone a long-term compressional uplifting and erosion since the Early Paleozoic,and also integrated with the upwarp of the Cambrian gypsum formation,thus forming two basic types of carbonate rock traps,namely,weathered-crust buried hills and insider anticline traps.

塔北隆起自早古生代以来经历了长期的挤压隆升剥蚀过程，结合寒武系膏盐的塑性上拱，形成了两种基本的碳酸盐岩圈闭类型，即风化壳潜山和内幕背斜圈闭。
