腾冲环形构造分析

AN ANALYSIS OF THE TENGCHONG CIRCULAR STRUCTURE

摘要: 环形构造的广泛发育是腾冲地区地质构造上的重要特点。在该区共解译出26个环形构造,并对其中的23个查明了成因,其中“腾冲环”是一个多级环形构造的集合体,是多次深部热动力活动的综合结果。

Abstract: The widespread development of circular structures represented by the "Tengchong ring" is an important feature of the geological structure in the Tengchong area. 26 structures have been interpreted as being circular structures in the area. Among these, the origin of 23 circular structures has been deter- mined. A magma heat source might exist in the underground of the area, and its multiple upward intrusions gave rise to granite masses, hydrothermal deposits, volcanos, geotherm and magma impact earthquakes. In terms of its outer configuration, the heat source is manifested by the shape of circular structures, and the "Tengchong ring" is made up of circular structures of multiple orders and is the result of multiple thermodynamic activity at depths.
