摘　　要：以湖北大冶铁山地区发育的矩形断裂石香肠为例,从地质研究的角度探索了矩形断裂石香肠体的黏度与其矿物组成和体积分数之间的关系。结果表明,当矩形断裂石香肠体中透辉石的体积分数越大,则石英、绢云母和方解石等矿物的体积分数越小,对应的石香肠体的黏度就越大;它们的能干性排序依次为:透辉石>石英和绢云母>方解石。The relationship between the rectangle boudinage structure and the mineral content, mineral composition is explored with an example of the boudinage structures developed in Tieshan of Hubei Provice. The result indicates that when the diopside＇s content increases, the content of the quartz.sericite and calcite decreases, and the boudin＇s viscosity increases. It is concluded that the competent order of the three minerals is diopside〉quartz and sericite〉calcite.
