Abstract

The Dudica deposit is located in the southern part of the Republic of North Macedonia (RNM), not far from the border with Greece in the Kozuf–Aridean volcanic region. The deposit is genetically associated with the Neogene igneous event (≥6 Ma, K/Ar), which is manifested at the intersection of northeast trending faults with the northwest trending Vardar fault zone. The REE spectrum of volcanic rocks here is characterized by a weak negative Eu anomaly and enrichment in light REE (LREE) relative to heavy REE (HREE). Mineralization is found in veins, veinlets, and dissemination; Cu concentration is around 0.5%; Au, up to 1 g/t. The principal ore minerals are chalcopyrite, bornite, enargite, covellite, chalcocite, and digenite; pyrite, galena, sphalerite, marcasite, and native gold are less frequent. The δ34S isotope composition falls within a narrow interval of +1.00 to +2.50‰, indicative of the igneous origin. The data obtained suggest that the Dudica deposit belongs to the class of the high-sulfidation epithermal deposits.

杜迪卡超热铜金矿床(北马其顿共和国)

摘要

Dudica矿床位于北马其顿共和国(RNM)的南部,在Kozuf-Aridean火山区与希腊的边界不远。该矿床与新近纪火成岩事件(≥6 Ma,K / Ar)在遗传上相关,这表现在东北向断裂与西北向瓦尔达断裂带的交汇处。此处的火山岩REE谱特征是负Eu异常弱,相对于重REE(HREE)轻REE(LREE)富集。矿物质存在于静脉,小静脉和传播中。铜浓度约为0.5%;金,最高1 g / t。主要的矿石矿物是黄铜矿,褐铁矿,硬石膏,玄武岩,黄铜矿和闪长岩。黄铁矿,方铅矿,闪锌矿,镁铁矿和原生金的频率较低。的δ 34同位素组成在+1.00至+ 2.50‰的窄区间内,表示火成因。获得的数据表明,Dudica矿床属于高硫化超热矿床。
