北莫卡辛山脉的金矿化是随着正长岩-斑岩的侵入作用之后而生成的。放射状和同心断裂伴随着正长岩-斑岩中心岩盖和小岩技的侵入。流体导致围岩蚀变和岩枝矿化及产生构造角砾岩。主岩盖的侵入年龄为66Ma,这是经7次放射性测量而被证实的。这个数字与3个小的蚀变斑岩的岩枝中的锆石年龄(59Ma)相比较大不了多少。蚀变斑岩的锆石年龄表明,这或 Gold mineralization in the North Mocincin Mountains is generated following the intrusive action of the syenite-porphyry. Radial and concentric fractures are accompanied by the intrusion of the cap rocks and small rocks in the center of the syenite-porphyry. Fluids cause alteration and rock mineralization of the surrounding rock and produce structural breccias. The age of the main rock cap was 66 Ma, which was confirmed by seven radioactive measurements. This figure is not much larger than the zircon age (59 Ma) in the branches of the three small altered porphyries. Zircon alteration porphyry ages indicate that this or
