贝加尔地区的地热场是极不均匀的。西伯利亚地台南部是构造稳和无震地区,其热流较低(1.0—1.3微卡/厘米~2秒)。在后贝加尔中度造山区,热流增高,平均达1.2—1.5微卡/厘米~2秒。在贝加尔裂谷带,新生代构造活动增高,而且地震活动性也高,其热流变化从0.4到4.0微卡/厘米~2秒。裂谷带大部分地区的热流均超过1.5微卡/厘米~2秒,这证明这种地区的地球内部受到很大加热。深部热状态的重大差别,导致水平温度梯 Geothermal field in Baikal region is extremely uneven. The southern part of the Siberian Platform is a structurally stable and earthquake-free area with a low heat flux (1.0-1.3 micromcs / cm ~ 2 seconds). In the post-Baikal moderate orogen, heat flow increased, with an average of 1.2-1.5 micromhos / cm ~ 2 seconds. In the Baikal rift zone, Cenozoic tectonic activity increased, and the seismic activity is also high, the heat flow changes from 0.4 to 4.0 micro-C / cm ~ 2 seconds. In most parts of the rift zone, the heat flux exceeded 1.5 microseconds / cm ~ 2 seconds, which proved that the interior of the earth in this area is greatly heated. Significant differences in deep thermal conditions result in horizontal temperature ladders
