Origin of tungsten-molybdenum mineralization at the Fox property, British Columbia

年，在不列颠哥伦比亚省中部的福克斯地产上发现了钨和钼矿化。 1999年在一个以前不为人知的花岗岩侵入体附近。随后的探测确定了 高品位矿化。现有的信息表明，这是一个夕卡岩型矿床，形成于 花岗岩浆与富碳酸盐岩石的相互作用。 福克斯地产的现任所有者Happy Creek Minerals Ltd.进行了钻探，钻探的岩床或堤坝状 矿化间隔之间的花岗岩岩体(1-10米厚)。这表明花岗岩可能不是 是典型的卵形侵入体，但形成与矿化围岩相互交错的地台状岩体。 这一点的确认对勘探和该物业的经济可行性具有重要意义。 这项研究的目的是确定福克斯地产的矿化来源和几何形状。这个 方法包括(1)地质填图，特别是可能控制矿体的局部构造特征 矿化分布；(2)花岗岩侵入体的地球化学和矿物学组成， 根据成矿潜力确定岩浆岩的丰度；(3)矿物学 以及(4)矿床中方解石的稳定同位素组成，以确定它是否 由花岗岩浆与富含碳酸盐的岩石相互作用或以其他方式形成的。这 信息将使工业合作伙伴能够设计更有效的勘探计划。

Tungsten and molybdenum mineralization was discovered on the Fox property in central British Columbia in 1999 in the vicinity of a previously unknown granitic intrusion. Subsequent exploration identified the presence of high-grade mineralization. The available information suggests a skarn-type deposit formed through the interaction of granitic magma with carbonate-rich rocks. Drilling by the current owners of the Fox property, Happy Creek Minerals Ltd., intersected sill- or dike-like bodies of granitic rock (1-10 m thick) between the mineralized intervals. This suggests that the granite may not be a typical ovoid intrusion but rather forms sill-like bodies interfingered with mineralized host rocks. Confirmation of this has implications for exploration and for the economic viability of the property. The purpose of this study is to determine the origin and geometry of the mineralization at the Fox property. The approach encompasses (1) geological mapping, in particular of local structural features that may control the distribution of the mineralization; (2) the geochemical and mineralogical composition of the granitc intrusion, to determine the fertility of the magmatic rock with respect to the mineralization potential; (3) the mineralogy of the host rocks; and (4) the stable isotopic composition of calcite from the deposit to determine whether it formed through the interaction of granitic magma with the carbonate-rich rocks, or in some other way. This information will enable the industrial partner to design a more efficient exploration program.
