在国家自然科学基金面上项目、重点项目和国家杰出青年基金项目的持续资助下,西北大学高山教授及其合作者于1992年以来研究提出了华北克拉通和秦岭-大别造山带下地壳拆沉作用的地质、地球化学和岩石物理学证据,并建立了下地壳拆沉作用的化学地球动力学模型。近年来他们通过对辽西晚侏罗世高镁中酸性火山岩的研究,发现这些火山岩不仅具有高镁-铬-镍-锶和低钇含量,还含有
Under the continuous funding of the National Natural Science Foundation of China, key projects and the National Outstanding Youth Fund project, Professor Gao Shan and his collaborators at Northwestern University have proposed to study the relationship between the North China Craton and the Qinling-Dabie orogenic belt during 1992 Sedimentary geology, geochemistry and petrophysics, and established the chemical geo-dynamics model of the delamination of the lower crust. In recent years, through their studies on the Late Jurassic high-Mg-acid volcanic rocks in western Liaoning, they found that these volcanic rocks not only have high Mg-Cr-Ni-Sr and low-Y content but also contain
