一、地热显示特征 (一)地热显示类型据初步统计,西藏高原的地热显示类型有如下几种: 1.水热爆炸:这是一种异常猛烈的水热活动现象,有人认为它应列入近期火山活动的范围。从现有资源来看,这种地热显示主要出现于西藏高原的南部。例如:岗巴县科作一带子一九七四年发生过一次规模较大的水热爆炸。当地牧民曾用牦牛绳探测其喉管深度, 探入深度达30余米尚未到底。爆炸坑很像近代火山口。萨迦县卡乌泉区也曾在二十多年前发生过一次水热爆炸。爆炸时石块从萨迦河右岸泉口飞至左岸,距离达100余米。羊八井
First, the geothermal display characteristics (a) type of geothermal display According to preliminary statistics, the Tibetan Plateau geothermal display types are the following: 1. Hydrothermal Explosion: This is an exceptionally violent hydrothermal activity, it was thought it should be included Recent volcanic activity range. From the available resources, this geothermal display mainly occurs in the southern part of the Tibetan plateau. For example: Gamba County Branch as a zone in 1974 there was a large scale hydrothermal explosion. Local herders have used yak rope to detect the depth of their pipes, exploration depth of 30 meters has not yet reached the end. Explosion pit like the modern crater. Sakha-chuen district of Sakya County also had a hydrothermal explosion more than 20 years ago. During the blast, the rocks flew from the right bank of Sakya River to the left bank at a distance of over 100 meters. Yangbajing
