摘要
凹山玢岩铁硫矿田近50年的勘查研究历史,是不断修改或否定旧的成因观点的历史.现已证实,这些矿体是一套组合矿床,具“三部八式”空间分布规律.据此,在70年代该矿田实勘储量成倍地增长;但现在找矿效果出现“滑坡”,矿田本身找矿潜力微弱;而新发现的雍镇矿田则较有希望.
The Aoshan porphyrite Fe-S orefield has a long exploration history of about fifty years with itsmetallogeny getting continuous modification or being negated and replaced by new genetic viewpoints. Ithas been established that the orefield is made up by a combination of deposits, with a spatial distribution of 'three parts and eight types'. In the seventies, the proved reserves of this orefield has doubled and redoubled year after year. Exploration result at this orefield now goes from bad to worse. Many exploration tools have been put into operation but no good result was achieved. It indicates that theAoshan orefield is very weak inits ore ipotentiality while the newly discovered Yongzhen ore-field mayhave very good prospects.
