摘要: 根据大地热流和岩石圈结构资料,探讨了云南岩石圈的地温分布。研究结果表明,全区存在3种地热类型:高地温型莫霍面温度>960℃,地壳地温梯度>2℃/100m;低地温型莫霍面温度<700℃,地壳地温梯度<1.5℃/100m;中等地温型莫霍面温度介于前二者之间,地壳地温梯度为1.5~2.0℃/100m。

Abstract: According to the data of the heat flow and lithospheric structure,and the correlative formula between the heat production A and the seismic velocity VP,the distribution of the lithospheric geotemperature in Yunnan has been studied. Three geothermal types exist in whole Yunnan region: high geotemperature type with the Moho temperature >960℃ and the crustal geothermal gradient >2℃/100m,low geotemperature one with the Moho temperature <700℃ and the crustal geothermal gradient <1.5℃/100m,and middle geotmeperature one with the Moho temperature lying between the former two types and the crustal geothermal gradient 1.5~ 2.0℃/100m.
