摘　　要：经野外地质调查和剖面研究,兴国县良村-高岭断裂带是由一系列平行侧列的韧脆性断裂带组成,各类构造岩发育,指示断裂带具多期活动;其对加里东期、印支期、燕山期花岗岩的侵位和兴国等断陷盆地的成生与发展、以及分布在兴国地区一系列的萤石矿、黄蜡石矿、金矿、钨矿等具有明显的控制作用。通过对该断裂带的进一步调查,新发现了黄蜡石矿;矿石具显微纤维状结构、隐晶质结构,块状、条带状构造。主要成分为玉髓,含量约92%~97%;矿石较坚硬,颜色以较纯净的蜡黄色、蛋青色为主,透明度较好,矿石品质中—良好。该矿的发现填补了兴国地区观赏石、宝玉石矿床类型的空白,为兴国宁都泰和一带寻找宝玉矿床开辟了新思路。The Liangcun-Gaolin fault zone in Xingguo county is composed of a series of parallel lateral ductile and brittle fault zones,and various types of tectonic rocks are developed through field geological survey and profile study,indicating that the fault zone has multi-stage activities.The fault zone obviously controls the intrusion of Caledonian,Indosinian and Yanshanian granites,the generation and development of Xingguo faulted basin,and the distribution of a series of fluorite,gold and tungsten deposits in Xingguo area.Meanwhile,a new chrismatite deposit has been discovered.Through analysis,the ore has microfibrous structure,cryptocrystalline structure,massive and banded structure.The main component is chalcedony,with the content of about 92%~97%;the ore is relatively hard,the color is mainly pure wax yellow and egg blue,the transparency is good,and the ore quality is medium to good.The discovery of the chrismatite deposit fills in the blank of the types of ornamental and gemstone deposits in the Xingguo area,and opens up a new way of thinking for searching for gem and jade deposits in the Xingguo-Ningdu-Taihe area.
