通过野外调查、岩石学研究和岩石地球化学采样分析,在苏格兰阿尔盖尔郡基默尔福德附近的纳卡洛基确定了一个与晚加里东期的次火山中心伴生的热液蚀变和矿化区.在面积为2.5Km~2的火成岩区包括有一个大的斑岩体、流动条带状英安岩、火成碎屑岩和一些热液角砾岩体.火成碎屑物质、英安岩与位于斑岩体内和边缘的不整合分布的角砾岩体之间的密切关系表明,它们是一种近火口的次火山深度的侵位作用.很明显,矿化流体从次火山带流出,并导致岩石广泛的蚀变和造成银、铜、钼、锌、铅、砷和金异常高的富集.
Through field surveys, petrological studies and petrochemical sampling analyzes, a hydrothermal alteration associated with the Late Caledonian subvolcanic center was identified at Nagar Rocky, near Kimerorf, Algerian, Scotland Mineralization area. The igneous rock area with an area of 2.5Km ~ 2 includes a large porphyry body, flowing banded dacite, pyroclastic rocks and some hydrothermal breccia bodies. , The close relationship between dacite and breccia bodies of unconformity distributed in and around the porphyry indicates that they are emplacement of a subvolcanic depth near the mouth and it is clear that the mineralized fluids from Secondary volcanic zones flow out and lead to extensive rock alteration and anomalous enrichment of silver, copper, molybdenum, zinc, lead, arsenic and gold.
