摘　　要：贵州西南部灰家堡金矿田位于国家级南盘江-右江成矿区带北部,探明金资源量370 t,近东西向灰家堡背斜为矿田控矿构造,矿体呈层状似层状产于背斜轴线300~1 000 m范围,埋深0~1 400 m,是理论找矿的典型范例。为燕山期成矿。构造地球化学弱信息指示了深部隐伏矿存在的可能,地球物理判别了深部构造形态,为深部工程验证提供间接依据;矿田内局部地段矿体未圈边、深部断裂发现厚大矿体;根据找矿预测模型,开展深部找矿预测,仍有较好找矿潜力。The Huijiabao gold ore field in the southwest of Guizhou is located in the northern part of the state-level Nanpanjiang-Youjiang metallogenic belt.The proven gold resource is 370 tons.The layer-like shape is produced in the anticline axis range of 300-1000m,and the burial depth is 0-1400m.It is a typical example of theoretical prospecting.For Yanshanian metallogenesis.Weak tectonic geochemical information indicates the possibility of deep concealed ores.Geophysical discrimination of deep tectonic forms provides an indirect basis for deep engineering verification.The thick ore bodies were found in the ore body without rims and deep faults in local sections.There is still a good prospecting potential in the prospecting model for deep prospecting.
