摘要
北衙金矿床是与碱性正长斑岩有关的具大型资源远景的一个多成因矿床。依据主要控矿条件———地层、岩浆岩、构造、蚀变、火山机构、表生作用等,综合矿区以往勘查资料,结合磁法、激电、地球化学、浅层地震和地球化学勘查成果,应用综合信息法、趋势外推法和多成因类型矿床预测法,确定了4个一级、2个二级找矿靶区,预测金资源量近百吨,认为北衙矿区已具备为一个大型金矿远景资源基地。
The Beiya gold deposit with a large-sized prospective reserves is a polygenetic deposit related to alkaline syenite porphyry. Judging by main ore-controlling conditions such as strata, magmatic rocks, structural alterations, volcanic apparatus, supergene processes etc., synthesizing former prospecting experiences, combining magnetic, induced polarization, geochemistry, shallow seismic, prospecting geochemistry, and applying the methods of comprehensive information, metallogenic prognosis, tendency extension, four first-classes and two second-classes prospecting targets have been identified with predicted gold resources about 100 ton. It is suggest that the Beiya gold district can become a basis of large gold deposit.
