摘要
屏边县位于云南滇东南地区,是我国西部一重要的新生代火山活动区域。研究区地表沟谷分布基性-超基性火山岩^([1]),其它地区广布震旦系屏边群板岩、长石石英细砂岩、含砾板岩。研究区所处一级大地构造单元华南褶皱系,分布马关-文山-西畴断裂、蒙自-广南-富宁断裂、蒙自-屏边断裂。周边地区沿断裂带附近有温泉出露,出露层位大多以哀牢山群为主,其次寒武系、泥盆系。通过对屏边地区地热地质条件分析研究探讨,对该区以后地热资源开发和利用提供地质依据。
The Miao Autonomous County of Pingbian is situated in southeastern Yunnan,an important Cenozoic volcanic activity region.Basic and ultrabasic volcanic rocks are distributed in the study area surface gullies and valleys,in other areas widely distributed Sinian Pingbian Group slate,feldspathic quartz fine-grained sandstone,pebbly slate.In study area situated primary geotectonic unit South China fold system has distributed Maguan-Wenshan-Xichou fault,Mengzi-Guangnan-Funing fault and Mengzi-Pingbian fault.In periphery areas near faulted belt have hot springs outcropped.Outcrop horizon is mostly Ailaoshan Group,Cambrian and Devonian systems the second.Through analytic study the paper has discussed geotherm geological condition in Pingbian area,and provided geological basis for geothermal resources exploitation and utilization in the area henceforth.
