花蕊石为蛇纹石大理岩(主要为含蛇纹石的方解石),白石英为石英矿石。经调查:在四川混为花蕊石药用的矿物有两种:一是白云石;二是不含蛇纹石的方解石。混为白石英药用的矿物为方解石。今将它们比较鉴别如下。一、蛇纹石1.性状鉴别:单斜晶系,单晶体少见,常呈致密块状及片状体,黄白、黄绿或灰绿色,具油脂或腊状样光泽,断口亦呈脂肪光泽,条痕白色,硬度2.5～4,比重2.5～2.6,有滑 The stone is a serpentine marble (predominantly serpentine calcite) and white quartz is a quartz ore. According to investigations, there are two kinds of minerals that are mixed with saplings in Sichuan: one is dolomite; the other is calcite without serpentine. The mineral mixed with white quartz is calcite. Now compare them as follows. First, serpentine 1. Character identification: monoclinic crystals, single crystal rare, often dense block and platelets, yellow and white, yellow-green or gray-green, with a grease or wax-like luster, the fracture was also fat luster, Streak white, hardness 2.5 ~ 4, specific gravity 2.5 ~ 2.6, there is slip
