摘　　要：结合在实际工作中的体会,提出和讨论了"地球深部包体与成矿关系"这一有意义的研究方向及其先导性科学问题。地球深部包体中镍、金、钼、钨等成矿元素的含量是不均一的,镍和金在地幔岩包体中含量最高,钼在玄武岩及镁铁质麻粒岩包体中最高,而钨在长英质麻粒岩和花岗岩类包体中含量最高。这些反映岩石圈和软流圈以及岩石圈的不同层次中镍、金、钼、钨等成矿元素的含量不均一,分别提供了地壳中镍、金、钼、钨矿床的初始物质来源。这一认识可能给镍、金、钼、钨等金属矿床和矿床集中区的战略预测提供一些新思路。The relationship of the deep-seated xenoliths to the mineralization and related guide scientific problems are put forward and discussed. The contents of Ni, Au, Mo, W of the deep-seated xenoliths and their host basalts from eastern China are inhomogeneous. The contents of Ni, Au are highest in the mantle-derived xenoliths; the contents of Mo, W are highest in the basalts and the mafic granulite, and the leptite and the granitoids, respectively. Those reflect the contents of Ni, Au, Mo, W in different spheres of Earth may be inhomogeneous. The result may have special significance on the controlling of the formation and distribution of Ni, Au, Mo, W deposits-concentrated districts.
