摘　　要：老挝石是近些年出现在雕刻石、篆刻印章石市场中的一支新秀,以其丰富的颜色、优良的品质受到人们的喜爱。由于矿区的保密性,对成矿条件和矿区信息一直是个谜。本文通过对矿区的实地考察,首次揭露南部老挝石的矿区信息,为老挝石的研究提供理论参考。南部老挝石矿区位于老挝南部的阿速坡省普翁县普甘洪山,原石以脉状产出于酸性火山岩(主要为潜流纹岩)中。根据矿石在野外的产出状况,把南部老挝石分为三大类:原生矿(山料)、残坡积矿(山水料)和河流冲洪积矿(田料);山料中主要的品种有棉体、五彩石、杜陵体、木木体和冻石等,山水料中主要有金丝田、朱砂红、水洞体和象牙体,田料中主要有黄皮田、白皮田、黑皮田(乌鸦皮)和多重皮田。矿区地处热带原始森林,开采困难,同时盗采严重,防盗采和矿区维护任务艰巨,老挝石来之不易!Laos stone is a rising star in the market of carved stone and seal stone in recent years,loved by people for its rich colors and excellent quality.Due to the confidentiality of the mining area,the mineralization conditions and mining information have always been a mystery.This article reveals for the first time the mining area information of southern Laos stone through field investigation,providing theoretical reference for the research of Laos stone.The southern Laos stone mining area is located in Phou Kanghong Mountain,Phouvong County,Attapu Province,southern Laos.The rough stones are produced in the form of veins in acidic volcanic rocks(mainly sub-rhyolite).According to the production status of ores in the wild,the southern Laos stones are divided into three categories:primary deposits(mountain ores),residual slope deposits(mountain and water ores),and river alluvial deposits(field ores);The main varieties of mountain ores include Mian stone,Five colored stone,Duling stone,Mumu stone,and Jelly stone;The main types of mountain and water ores include Golden silk field stone,Cinnabar red stone,Water cave stone,and Ivory stone;There are mainly Yellow skin field stone,White skin field stone,Black skin field stone(crow skin),and Multiple skin field stone in the field ores.The mining area is located in a tropical primeval forest,making mining difficult.At the same time,illegal mining is severe,and the tasks of preventing illegal mining and maintaining the mining area are arduous.It is not easy for Laos stone to obtain!
