摘　　要：黄埠岭金矿位于灵北断裂带西南段,其深部及其外围区仍有找矿潜力,找矿远景区包括:Ⅰ号远景区,位于灵北断裂带盛家-马埠徐家段,发育遥感泥化蚀变和As-Sb-Au-Ag-Cu元素组合异常,针对该区覆土厚、露头少的特点,宜采用高精度瞬变电磁法(TEM)和音频大地电磁法(AMT)等物探技术探测灵北断裂带"主断裂"及其上盘次级断裂位置和深部变化情况;Ⅱ号远景区,位于七厘山矿区,鉴于主矿体走向延长较大及上盘遥感泥化蚀变异常和Au-Ag-Cu-As-Sb元素组合异常的情况,在其深部寻找"第二富集带"可做为一个主要找矿方向,宜选择典型剖面开展音频大地电磁法(AMT法)测量,探测400m以下深度的断裂带及低阻异常分布位置,为钻探工程验证提供依据;Ⅲ号远景区,位于灵北断裂带凤凰庄段。发育Au-Ag-Cu-As-Sb元素组合异常和金矿化,针对该区露头发育、化探异常清晰的特点,宜采用大比例尺构造与蚀变填图,结合构造地球化学法加密,查明灵北断裂带主带及次级含矿或蚀变断裂的找矿潜力与找矿有利部位。Located in the southwest section of Lingbei fault zone, Huangbuling gold deposit has a good potential for prospecting prediction. Prospecting areas includes Section I from Shengjia to Mabuxujia in Lingbei fault zone,which is characterized by argillic alteration of remote sensing and abnormal combination of elements As-Sb-Au-Ag-Cu. It has been suggested that geophysical techniques such as TEM and AMT be used in Lingbei fault zone to probe occurrence changes of the ＂main fault＂ and its secondary fractures on the hanging wall,according to the characteristics of the earth cover and the outcrop of the area. Section II is in Qilishan mining area. In view of the great extention of its orebodies and its argillic alteration of remote sensing and abnormal combination of elements Au-Ag-Cu-As-Sb, when ＂the second enrichment zone＂ is being searched in deep areas as a main prospecting direction,AMT measuring is suggested to be used in a typical section to probe fault zones and Low resistivity anomalies below -400m,and to provide the basis for drilling engineering verification. Section Ⅲ is in Fenghuangzhuang with abnormal combination of elements Au-Ag-Cu-As-Sb and gold mineralization points. In this section,large-scale structure and alteration mapping method along with tectonogeoehemical sampling method should be used to search for the main fault and secondary fractures of Lingbei fault zone which have greater prospecting potential, because of the widespread-exposed rocks and the apparent geochemical anomalies in this section.
