摘要
以壳体大地构造理论为基础,根据滇西三江地区的基本地质事实,对前人的观点进行重新认识和修正,首次提出了该区迄今最全面、最系统的壳体大地构造单元划分方案,将其细分为4个壳段,11个次级单元和3个挤压聚合带,从新的角度揭示了该区区域地质构造的时空演化规律,为区域成矿规律提供了重要的科学依据。
Based on the crustobody geotectonic theory and in terms of the basic geological backgrounds of threeriver areas in western Yunnan province and a reinvestigation and revision of the viewpoints by previous scholars, the author proposed a plan of division of geotectonic units for the first time in this area, and the plan may be the most comprehensive and systemic classification scheme so far. Here the crustbody can be subdivided into four crustosegments including eleven secondary elements and three converging - connection zones, which can not only reveal the spatial - temporal evolutional laws of regional geological structures from a new angle, but also provide the important scientific basis for understanding the laws of regional mineralization in this area.
