对高压捕虏体研究的结果表明,在大多数大陆地区下面,镁铁质岩石不仅在下部地壳中占优势,而且在地幔顶部也非常丰富。根据捕虏体资料,我们就可以建立地热和地层剖面,并得出能对地球物理数据进行具体解释的岩石学限制条件和物理参数。在具有高热流的大陆地区,象地震折射资料所确定的那样,莫霍面所处的深度可能比地壳-地幔界面还深。克拉通地区的与“热”地区的下部地壳-上地幔剖面的地震差异,可单用温度变化来解释,而不需要岩性有大的差异。
Results from high-pressure xenoliths show that mafic rocks dominate not only the lower crust but also the top of the mantle under most continental areas. Based on xenolith data, we can establish geothermal and stratigraphic profiles and derive petrology constraints and physical parameters that can be used to explain geophysical data. In the continent with high heat flux, as determined by seismic refraction data, the depth of the Moho may be deeper than the crust-mantle interface. The differences between the earthquakes in the Lower Craton and the Upper Mantle in the “Craton” region and in the “hot” region can be explained solely by temperature changes without the need for large differences in lithology.
