摘要
选取贵州西部玄武岩为研究对象,通过岩矿鉴定、化学组成分析、热重差热试验、拉丝试验,结合区域地质资料,探讨了贵州西部适宜制造玄武岩纤维的岩石特征。研究认为,贵州西部地区适合生产玄武岩纤维的岩石类型主要是间隐间粒玄武岩和拉斑玄武岩,具有块状构造,析晶温度在1270~1400℃等特征。通过对可作玄武岩纤维的玄武岩在贵州西部纵向、横向对比研究,其中适宜制造玄武岩纤维的区域较好的是毕节市的织金县、大方县、七星关区、赫章县和威宁县,其次为六盘水市,最差的是黔西南州和安顺市。
The characteristics basalt rocks,suitable for making basalt fibers,in the western Guizhou have been explored through the rock identification,chemical composition analysis,heat-weight difference thermal test,and wire drawing test,with the combination of regional geological data.The study shows that the rocks suitable for producing basalt fibers in the western Guizhou are mainly interstitial intergranular basalt and tholeiitic basalt,with massive structure and crystallization temperatures of 1270-1400°C.Through the comparative study on the longitudinal and horizontal distribution of basalts that can be used to make basalt fibers in the western Guizhou,it is concluded that the basalts suitable for making good quality basalt fibers are distributed mainly in Zhijin County,Dafang County,Qixingguan District,Hezhang County and Weining County of Bijie City.The basalts suitable for making relatively low quality basalt fibers are distributed in Liupanshui City.The basalts distributed in the Southwestern Guizhou Prefecture and Anshun City only can be used to produce the worst quality basalt fiber.
