THE STUDY OF METAMORPHIC CORE COMPLEXES IN THE XUEFENGSHAN AREA
-
摘要: 笔者通过对雪峰山地区变质核杂岩的发现和研究,认为它与科迪勒拉变质核杂岩既有相似之处,但又不完全相同,具有独特的构造特征和演化历史。文中还以沃溪金矿为例,讨论了变质核杂岩对脉金矿床的控制作用。Abstract: After the study of the metamorphic core complex of the Xuefengshan,Hunan Province,the writers found that it is similar to the Cordilleran counterpart in structure,deformation mechanics,and detachment features,except for that its upper plate is composed of Neoproterozoic very low-grade metamorphic rock and Paleozoic strata and that the complex was formed between Late Devonian and Early Carboniferous.Its control of the Woxi vein gold deposit is discussed in the paper.
