摘要:
烟筒砬子地区位于延边上叠盆地北部，两江—明月金多金属成矿带的北东部，成矿条件良好。该地区主要发育金砷矿化，矿体主要产于二叠系庙岭组中，受北东向断裂及次级断裂控制。1∶1万土壤地球化学测量结果显示，As、Au、Ag、Sb、Pb分布不均匀，离散程度较大，有浓集趋势，表明其具有一定找矿潜力；共圈定Au异常18处，综合异常6处。通过异常查证，确定由Au、Ag、Cu、Zn、As、Sb、Pb、W、Mo、Bi元素组成的HT-6综合异常为矿致异常，探获了3条矿体。对烟筒砬子地区找矿前景进行了分析，认为其具有良好的找矿前景，可以对该地区下一步找矿勘查及邻区找矿勘查工作提供借鉴。

Abstract:
Yantonglazi District is located in north of the Yanbian superimposed basin,the northeastern part of Liangjiang-Mingyue gold polymetallic metallogenic belt with good ore-forming conditions.Gold arsenic mineralization is mainly developed in this area,and the ore bodies mainly occur in the Permian Miaoling Formation and are controlled by NE-trending faults and secondary faults.The results of 1∶10 000 soil geochemical survey show that As,Au,Ag,Sb and Pb are unevenly distributed and highly dispersed with concentration trend,indicating that they have certain prospecting potential,and 18 Au anomalies and 6 comprehensive anomalies are delineated.Through anomaly verification,it is determined that the HT-6 comprehensive anomaly composed of Au,Ag,Cu,Zn,As,Sb,Pb,W, Mo and Bi elements is ore-induced anomaly,and 3 ore bodies have been discovered.Based on the analysis of the prospecting prospect in Yantonglazi District,it is considered that it has good prospecting prospects,which can be used as a reference for the next-step ore prospecting and exploration in this area and its neighboring areas.
