摘　　要：本文通过EPMA对钒铝矿和砷钡铅矿化学成分的分析和制作V、As、P元素等值线图及含量变化剖面图,查明矿物组分的不均匀性与颜色分带和组分分带的对应关系,并推断出成矿溶液对晶体生长的影响。By the analyses of chemical composition of vanadinite and arsenicvanadinite by means of EPMA and by the construction of isograms andisogradient maps showing the distribution of the elements Ⅴ, As and P,it has been discovered that the distributive nonuniformity of chemicalcomposition of mineral corresponds with color zoning and compositionzoning. The impact of ore-forming solutions upon crystal growth hasthus been deduced.
