According to the characteristic of Co/Ni value and deep structures and basing on the published genesis of Fanshan apatite-magretite deposit,this paper analyses the origin of magnetite-apatite rock occures in the upper part of apatite rock.
在矾山磷铁矿床已有成因认识的基础上 ,通过矿床微量元素Co/Ni值特征、矿床地质构造、巷道地质素描和大地构造背景的分析 ,认为矾山磷铁矿床的磁铁磷灰石岩和磷灰石岩形成时是液态重力分异的正常顺序 :两者近于直立或磷灰石岩上覆于磁铁磷灰石岩之上。
Gigantic apatite_magnetite deposits occur in layered rocks.
层状岩系中赋存巨大磁铁磷灰石矿床。
Magnetic iron oxide/hydroxyapatite was obtained by co_precipitation method.
首先通过化学沉淀法制备磁性氧化铁羟基磷灰石(Fe3O4/HA),然后以壳聚糖(CS)为基体,利用原位沉析法将Fe3O4/HA与CS复合,制得磁性Fe3O4/HA/CS复合材料。
