摘要
和平硼矿床属中低温热液交代型。它是我国首次发现的中型硅硼钙石矿床,可直接利用于玻璃工业。矿体赋存于上侏罗统劳村组底部砾岩中,并受其砾岩成分和构造的控制。硼质来源于隐伏花岗闪长岩体,在温度为306～120℃、pH为6.7、Eh为58.63mV的弱酸氧化环境、封闭条件下富集成矿。
The Heping boron deposit is a meso-epithermal metasomatic datolite type medium-sized oncealed boron deposit discovered for the first time in china, and its ores can be used irectly in glass industry. The ore body occurs in basal conglomerate of Upper Triassic Laocun ormation and is controlled by composition of the gravels and structures. The boron materials ere derived from the concealed granodiorite body and, at the temperature of 306—120℃ and nder the weakly acid, oxidizing and closed condition with pH 6.7 and Eh 58.63mV, concentrated o form ore deposit. The ores show granuloblastic texture, poikiloblastic texture and etasomatic texture.
