近一个时期的研究表明,接近地表的金矿在不同含矿地区广泛分布,这种矿床皆为火山成因,特别与火山机构和中酸性火山岩关系极为密切,此种关系是众所周知的,这种矿床的特点是金在矿体的个别地段—所谓的矿柱部位富集.大家熟知的矿床,工业矿体只占整个合矿岩脉的1/600,在已知的有一百多条脉的(CLLIA)金矿床80%的金是从矿囊中和矿脉开采的.矿脉的规模与其中矿体之间类似的比例关系,在
Recent studies have shown that close to the surface gold deposits in different ore-bearing areas are widely distributed, all of these deposits are volcanogenic, especially with the volcano and intermediate acidic volcanic rock very close relationship, it is well known that this deposit Is characterized by the enrichment of gold in some parts of the ore body, the so-called pillared part of a well known mineral deposit, which accounts for only 1/600 of the total colliery veins and is known to have over a hundred veins 80% of the gold in the CLLIA gold deposit is mined from the orebodies and from the veins, and the size of the veins is similar to the proportion between them
