摘要:

为了解决广西罗城县记洞湾矿区深部找矿问题,在矿区开展了地电化学提取法寻找隐伏锡铜多金属矿的研究工作。在已知矿体剖面上发现的地电化学提取异常与矿体对应度较高,能较好地反映出锡铜矿体的埋藏位置,说明地电化学提取法在罗城县记洞湾矿区找矿是可行有效的。利用因子分析和聚类分析得出4组成矿元素组合F1(Cu-Ni-Co-Pb-Zn)、F2(W-Sn)、F3(Ag-Bi)和F4(B),表明研究区地电化学异常规模大且比较集中,清晰度高,异常浓度分带明显,从而划分出A类靶区2个,B类靶区2个,各预测靶区与区内已知锡铜多金属矿体有着相似的成矿地质条件。根据地电化学研究结果,认为该研究区具备有利的成矿地质条件,是寻找隐伏锡铜多金属矿体的有利地段,具有较大的找矿潜力。

Abstract:

In order to solve the deep prospecting problem of Jidongwan mining area in Luocheng County,Guangxi,the geo-electrochemical extraction method was carried out to explore concealed tin-copper polymetallic deposits.It is found that the geo-electrochemical extraction anomaly,shown above the known orebody profile,exists a high correspondence with the orebody,which can better reflect the concealed tin-copper orebody.It means that the geo-electrochemical extraction method is feasible to find tin-copper polymetallic deposits in the Jidongwan mining area,and it has good effectiveness and adaptability. The factor analysis of the geo-electrochemical extraction element data in the study area was conducted.The results show that the elements can be classified into four elemental assemblages,namely,F1(Cu-Ni-Co-Pb-Zn),F2(Ag-Bi),F3(W-Sn) and F4(B).According to the spatial distribution pattern of single elements and elemental assemblages anomalies extracted by the geo-electrochemical approach,it can be seen that each element has a high anomalous definition,intensity,and good continuity.Besides,the elemental assemblages are anomalously well-nested and clearly zoned.Based on the analysis of the spatial distribution characteristics of the geoelectric extraction elements and the combined element anomalies in the Jidongwan mining area,according to the size,intensity,morphological characteristics and the degree of agreement between the anomalies,combined with the geological location and geological characteristics and other factors, two A type target areas(A-1,A-2) and two B type target areas(B-1,B-2)are delineated in the study area.It is believed that the study area has favorable ore-forming geological conditions,which is a favorable location for searching for concealed tin-copper polymetallic orebodies,and has great prospecting potential.

Key words: tin-copper polymetallic ore, geoelectrochemical extraction method, abnormal characteristics, prospecting prediction, Jidongwan mining area, Guangxi
