摘要
位于西昆仑山腹地的瓦卡、班迪尔两幅1∶5万区调填图内的地质构造特征是西昆仑造山带的一个缩影,特别是前震旦系变质地层和下拉夫迭组的系统研究和时代、层系的重新厘定,为该区构造系统的建立和构造单元的重新划分奠定了坚实的基础;从新的资料出发对康西瓦—西昆中断裂的性质、延伸及形成时代提出了新的看法,这些认识会对西昆仑造山带的进一步研究提供新的参考资料。
The geologic and tectonic characteristics in the area of Waka and Bandier, shown from the regional geology surveying and mapping with the scale of 1∶50,000, are the epitome of West Kunlun Mt orogen. Systematic study and new knowledge about the time and sequence of pre-Sinian and early Cretaceous Xiafuladie Formation have got a solid basis for the construction of the tectonic system and division of the tectonic elements. A new idea about the characteristic and stretch as well as formation time of Kangxiwa-West Kunlun fault was proposed on the basis of the new document, which would give some useful information for further study to the West Kunlun Mt Orogen.
