多年来一直认为,铍主要是在与花岗岩有关的高温伟晶岩和云英岩矿床内才能富集,其中绿柱石是主要镀矿物。自从改变找矿方针,开始寻找中低温的硅铍石矿床以来,发现了各种类型的铍矿化,其中最有价值的是含硅铍石的蚀变火山岩和硅铍石—萤石建造的交代岩。最富的矿床形成于弱碱性和碱性花岗岩类小岩体的侵入体上部地段。岩体产于碳酸盐岩石或基性岩之中。矿化赋存在岩性有利层位范围内的各种岩脉(微正长岩、闪长玢岩等)的交汇或结合处。当灰岩与硅
For many years, beryllium has been believed to be mainly enriched in high-temperature pegmatite and dolomitic deposits associated with granites, with beryl being the main mineral. Since changing the ore prospecting direction and beginning to search for low-temperature and low-temperature silica-beryl deposits, various types of beryllium mineralization have been discovered. The most valuable of these are beryllium-containing altered volcanics and silico-beryllium-fluorite Confirmation rock. The richest deposits are formed in the upper part of intrusive rocks of weakly alkaline and alkaline granitoids. Rock mass produced in carbonate rock or basic rock. Mineralization occurs in the lithologic favorable horizon within a variety of dikes (syenite, diorite porphyrite, etc.) of the intersection or junction. When limestone and silicon
