摘要
在获得云南一批大地热流、岩石放射性生热率数据的基础上,结合研究区地质—地球物理资料,提出并建立了云南三江地区大陆碰撞造山带复合叠加型岩石圈热结构模式。这一模式有助于了解云南三江地区三叠纪以来构造作用产生的深部热背景,从地热学角度探讨了区内岩浆岩、火山岩和变质岩的分布规律。
The thermal structure of the lithosphere in continental collision orogens is afrontier subject in the current study of theoretical geothermics. Based on systematicborehole geotemperature logging, terrestrial heat flow measurements and radiogenicheat production determination, combined with geological and geophysical data, amodel of compound and superimposed thermal structure of the lithosphere in conti-nental collision orogens in the Sanjiang region of Yunnan is proposed. This model isconducive to understanding the deep thermal setting produced by tectonism sincethe Triassic in the region. The distributive pattern of magmatic,volcanic and meta-morphic rocks is discussed from the geothermal perspective.
