锰褐磷锂矿虽早在1921年首次在美国加里福尼亚州的伟晶岩中发现,而在我国目前仅在新疆和秦岭伟晶岩中发现有褐磷锂矿的变种—锰褐磷锂矿存在。由于锰褐磷锂矿是半透明矿物,前人在研究中往往忽略了其反光镜下的性质。笔者对采自秦岭伟晶岩中的锰褐磷锂矿进行了研究,并补充了反光镜下的性质,首次测定了反射率和计算了颜色指数。 Although the manganese-lithophilic lithium-manganese deposit was first discovered in pegmatite of California in 1921 in the United States, at present it is found in China only in the pegmatites of Qinling Mountains and Xinjiang that there is a breed of lithophilic lithium-manganese brown phosphorus Lithium exists. As manganese, lithium, phosphorus and lithium is a translucent mineral, previous studies often overlook the nature of its mirror. The authors studied the extraction of manganese, phosphorus and phosphorus from Qinling pegmatite and added the properties under the mirror. The reflectivity and the color index were measured for the first time.
