摘　　要：通过X-射线衍射仪和扫描电镜,检测分析了甘肃地区4个典型矿点凹凸棒石的矿物组成。结果表明:甘肃地区凹凸棒石的矿物组成相似,主要含有凹凸棒石、石英、长石、海泡石、石膏、绿脱石、白云石、蒙脱石、云母等。凹凸棒石的各矿物含量差别较大,临泽杨台洼地区绿色凹凸棒石的纯度最高为34.9%,靖远高湾红色凹凸棒石的纯度最低为19.3%;石英的含量均在15%以上,其中临泽板桥镇的含量最高为21.8%;长石含量均在12%以上,靖远高湾的含量最高为19.8%;绿脱石、白云石、石膏、蒙脱石和云母的含量均在10%以下。The mineral composition of attapulgite clay from the typical mines in Gansu area using XRD and SEM was analysed. The conclusion： mineral composition of attapulgite from the typical mines are similar, mainly containing attapulgite, quartz, feldspar, sepiolite, leuchtenberg, dolomite, montmorillonite, mica. The mineral content of attapulgite clay has a slightly difference, the mineral content of attapulgite from Yangtaiwa is 34.9%, the mineral content of attapulgite from Gaowan is 19. 3% ;The contents of quartz are more than 15% , and the highest one from Banqiao is 21.8% ; Feldspar content from four typical mines are more than 12%, and the highest one from Gaowan is 19.8% ; The contents of dolomite, gypsum, montmorillonite and mica are below 10%.
