collinsite

In hand specimens Mg-sarcopside is yallowish pink,and browish pink,in colour with glassy luster.

镁斜磷铁锰矿产于四川某地含铍伟晶岩的中部，该伟晶岩分带性弱，但钠长石化发育，与之共生的矿物有镁电气石、蓝色绿柱石、石榴石、白云母、石英及黄铁矿等。

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。
