摘要
指出前人在研究腾冲地热时的工作模式及其工作结果 ,大多数只能反映腾冲水热活动区的静态特征和横向特征。同时提出 :在腾冲热海开展地下流体观测的目的 ,就是通过对与现代幔源岩浆活动相关的热海水热显示区内部分泉点进行长期的连续观测 ,发现热海地下流体的动态变化规律 ,预测热海热田的发展趋势。通过观测研究得出 :(1)热海地区的地热活动处于不断变化之中 ,这种变化可能和该区的地下幔源物质活动有关 ;(2 )热海热田自 1993年以来不断发生水热爆炸现象的主要原因 :一是沿老滚锅、大滚锅、小滚锅、黄瓜箐一线展布的南北向深断裂活动加强 ,二是地下幔源物质活动加剧。
The authors consider that the working style and results made by previous researchers only reflect static and transersal features in Tengchong hot water areas.It is pointed out that the purpose of underground fluid obseration is to discover dynamic variation and predict development tendency through measurements for a long period of time.It is obtained from observations:(1)the geothermal activity is changing all the time,which is probably related to substances in mantle;(2)there are two reasons to explain the eruption of hot water from 1993,one is strength of fault activity along Laogunguo,Dagunguo,Xiaogunguo and Huangguaqing,and another is rapid changes of substances in mantle.
