流体包裹体在盆地热史研究中的应用与问题讨论

Application and discussion on problems of fluid inclusion study in thermal history of the basin

矿物流体包裹体中保留了大量盆地形成过程中成矿流体的温度、压力等信息,因而在盆地的热史研究中得到了广泛的应用。介绍了流体包裹体在盆地古地温及古地温梯度中应用的基本情况,分析了该方法的优点及存在的一些问题,并指出了多种古温标法相互对比、相互验证与相互补充才是盆地热史研究的有效方法。

During the forming process of a basin, the messages of ore - forming fluid, such as tempreture and pressure have been preserved in mineral fluid inclusion, which becomes widly used in the thermal history of the basin. This paper introduces the applied status of fluid inclusion in palaeofethermal and the palaeothermal gradient, analyzes the advantages and disadvantages, and points out that the method of comparison, verification and complementation of several palaeotempreture scales with one another is the most effective way to study the thermal history of the basin
