去年镇沅县有关部门在和平乡发现了稀有的蓝色花岗石资源。其矿区位于哀牢山中段的大金山,紧临恩(乐)——水(塘)公路,交通较为方便。矿石的矿物成份主要为长石和石英,其次为云母等。其中石英呈蓝色,长石呈白色和淡绿色,云母呈黑色,三种矿物分布均匀,色斑、色线甚少,将其加工成装饰板材,色彩素雅美观,装饰效果较好。按矿物斑晶的大小,可将这种花岗石分成两个亚品种,一种是石英和长石班晶粒径大致相等,为4——10mm,整体色调为灰蓝色的“小蓝花”;另一种是白色的长石斑晶远比石英斑晶大,
Last year, relevant departments of Zhenyi County discovered rare blue granite resources in Heping Township. Its mining area is located in Dajin Mountain in the middle section of Ailaoshan Mountain, close to the En (Le)-Water (Tang) Highway, and the transportation is more convenient. The mineral composition of the ore is mainly feldspar and quartz, followed by mica. Among them, quartz is blue, feldspar is white and light green, and mica is black. Three kinds of minerals are evenly distributed. There are very few stains and color lines. They are processed into decorative plates with elegant and beautiful colors and good decorative effect. According to the size of the mineral speckles, this granite can be divided into two sub-species, one is quartz and feldspar sub-grain size is approximately equal to 4 - 10mm, the overall tone is gray blue “small blue flowers ”The other is the white feldspar crystal is much larger than the quartz crystal.
