在匈牙利西北部,正在开发一个不寻常的大型斑岩铜矿.雷科斯克斑岩铜矿之所以特殊,是因为它埋藏极深,矿体的顶部在地表下2000英尺处;因为位于中心的铜-钼斑岩区被夕卡岩和混合的硫化物(Zn、Pb、Cu)矿化分带包围;还因为它是发育于巴尔干-喀尔巴阡大铜-钼带内斑岩的最北部和最西部的代表.该斑岩带包括了苏联境内的几个大型矿床、伊朗的萨彻斯米斑岩、保加利亚的麦德和埃拉齐特矿床及南斯拉夫的博马丹皮克斑岩.除了雷科斯克矿床之外,上述的所有矿床都是近地表的,露天开采的或极个别是在较浅部的地下开采的.雷科斯克位于匈牙利北部马特劳山区内埃格尔城的西南.雷科斯克矿床的核心是一个安山岩侵入体,具有典型的斑岩浸染状的黄铜矿矿化.在这一核心的周围,侵入体蚀变和矿化了三迭纪灰岩,形成了一个品位高于核心的交代夕卡岩矿床.夕卡岩带外,灰岩内有混合的硫化物矿.
An unusual large-scale porphyry copper mine is being developed in northwestern Hungary, and the Rexsk porphyry copper mine is special because it is deeply buried with the top of the ore body about 2,000 feet below the surface; The copper-molybdenum porphyry is surrounded by skarn and mixed sulphide (Zn, Pb, Cu) mineralization belts; also because it is the most abundant porphyry in the Balkan-Carpathian copper-molybdenum belt North and West of the porphyry belt. The porphyry belt includes several large deposits in the Soviet Union, Sesmese porphyry in Iran, the Medea and Elazit deposits in Bulgaria and the Bomandak porphyry in Yugoslavia All of the aforementioned deposits, except for the Rexsk deposit, are near-surface, open-pit, or extremely shallow, mined underground. Leksk is located in Eger, in the Matrau mountain region of northern Hungary At the heart of the Rexsk deposit is an andesite intrusive with typical porphyry disseminated chalcopyrite mineralization around which the intrusive altered and mineralized Triassic limestone, A higher-grade core skarn deposit has been formed , Have a mixed sulfide ore in the limestone.
