摘要
通过对小红土湾地区开展1∶2.5万地球化学测量,圈定出4处以Sn、Bi、Mo、Zn等为主要元素的综合异常,异常具有矿致特征,通过进一步异常查证工作,目前地表共圈定出17条锡矿体。进一步说明采用的1∶2.5万地球化学测量工作方法的技术有效性,可在类似景观区推广应用。有利的地质成矿条件、优越的化探异常及槽探工程揭露出大量矿体的存在,证明该地区寻找矽卡岩型锡矿床具有较大的潜力。
The 1∶25000 geochemical survey was carried out in the Xiaohongtu Bay area,and four comprehensive anomalies with Sn,Bi,Mo,Zn,etc.as the main elements were delineated,and the anomalies have ore-induced characteristics.Through further anomaly verification,a total of 17 tin ore bodies have been delineated on the surface.It further shows that the 1∶25000 geochemical survey technique adopted in this study is effective and can be popularized and applied in similar landscape areas.Favorable geological and metallogenic conditions,superior geochemical anomalies and good metallogenic facts prove that skarn tin deposit has great potential in this area.
