Ground magnetic surveys conducted in Suyoc, Mankayan, Benguet led to the delineation of features related to epithermal and porphyry copper targets in the area. High reduced to equator (RTE) anomalies are observed in areas with epithermal mineralization. The high RTE anomalies are attributed to hydrothermally altered rock with quartz veins. The previously recognized porphyry copper prospect in Palasaan (Mohong Hill) is characterized by low RTE anomaly surrounded by a high RTE anomaly. One explanation for this signature is the possible presence of a magnetic core and the destruction or absence of magnetite in the alteration haloes at the periphery of a porphyry prospect. Areas such as Mangga and Liten exhibit the same magnetic signatures. This distinct magnetic pattern coupled with observed alteration and mineralization signatures led to the interpretation of prospective blind porphyry deposits in these localities. Results of the study reveal the applicability of ground magnetic data in characterizing and extracting a potential area of mineralized zones at a regional scale.

菲律宾曼卡延矿区苏约克地磁资料解释

在 Suyoc、Mankayan、Benguet 进行的地磁勘测导致描绘了与该地区的超热液和斑岩铜目标相关的特征。在具有超热成矿作用的地区观察到高度还原到赤道 (RTE) 异常。高 RTE 异常归因于具有石英脉的热液蚀变岩石。Palasaan（磨洪山）的先前公认的斑岩铜矿区的特点是低 RTE 异常被高 RTE 异常包围。对此特征的一种解释是，在斑岩矿床外围的蚀变晕中可能存在磁芯和磁铁矿的破坏或缺失。Mangga 和 Liten 等区域表现出相同的磁性特征。这种独特的磁性模式加上观察到的蚀变和矿化特征导致对这些地区潜在的盲斑岩矿床的解释。研究结果揭示了地面磁数据在区域尺度上表征和提取矿化带的潜在区域的适用性。
