Hydrothermal native metal-arsenide (five-element or Ag-Bi-Co-Ni-As±U) veins are a globally occurring mineralization style, which is particularly prevalent across Central Europe. Due to the limited amount of geochronological data available, the timing and the detailed geodynamic setting in which this mineralization style formed remains insufficiently understood. To fill this gap in knowledge, we applied innovative LA-ICP-MS U-Pb geochronology on carbonates from six districts in the Erzgebirge/Krušné Hory province of Germany and Czech Republic in order to constrain the timing of ore formation in the context of the geodynamic framework of Central Europe.

In situ U-Pb ages of twelve samples, including dolomite-ankerite, calcite, and siderite coeval with Ni-Co-Fe-arsenides, range from ~129 to ~86 Ma. The ages of native metal-arsenide and fluorite-barite-Pb-Zn veins from the same occurrence (Annaberg-Buchholz district) are found to be consistent with each other, providing new and direct geochronological evidence that these two styles of mineralization are genetically related and may form coevally within one hydrothermal system.

Complemented with available geochronological data from other occurrences, the formation of native metal-arsenide assemblage in Central Europe can be related to continental rifting affiliated with the Mesozoic opening of the Atlantic and Alpine Tethys Oceans (~200–100 Ma). The youngest age of ~86 Ma coincide with basin inversion associated with the onset of Alpine compressional tectonics, which most likely terminates the conditions favorable for the formation of native metal-arsenide mineralization in Europe. The onset of native metal-arsenide formation in proximal positions to the main rift axis starts at ~230–200 Ma (Penninic Alps, Anti-Atlas). In contrast, it occurs systematically later with increasing distance to the rift axis – namely at ~200–130 Ma in intermediate (Schwarzwald, Odenwald, Spessart) and ~140–86 Ma in distal (Erzgebirge, Harz) positions to the main rift axis.

热液天然金属砷化物（五元素或 Ag-Bi-Co-Ni-As±U）矿脉是一种全球性的矿化类型，在中欧尤为普遍。由于可用的地质年代学数据有限，人们对这种矿化类型形成的时间和详细的地球动力学环境仍知之甚少。为了填补这一知识空白，我们对德国和捷克共和国 Erzgebirge/Krušné Hory 省六个地区的碳酸盐岩应用了创新的 LA-ICP-MS U-Pb 年代学，以限制矿石形成的时间。中欧地球动力学框架。

十二个样品的原位 U-Pb 年龄范围从~129 到~86 Ma，包括白云石-铁橄榄石、方解石和菱铁矿与 Ni-Co-Fe-砷化物。发现同一矿点（Annaberg-Buchholz 区）的天然金属砷化物和萤石-重晶石-Pb-Zn 矿脉的年龄相互一致，为这两种成矿类型在成因上提供了新的直接地质年代学证据并且可能在一个热液系统内同时形成。

与其他事件的可用地质年代学数据相辅相成，中欧原生金属砷化物组合的形成可能与与大西洋和高山特提斯洋（~200-100 Ma）的中生代开口有关的大陆裂谷有关。大约 86 Ma 的最年轻年龄与与高山挤压构造开始相关的盆地反转相吻合，这很可能终止了有利于欧洲原生金属砷矿化形成的条件。在主裂谷轴的近端位置开始形成天然金属砷化物，开始于~230-200 Ma（Pennic Alps，Anti-Atlas）。相比之下，随着距裂谷轴距离的增加，它系统性地稍后发生——即中间（Schwarzwald、Odenwald、Spessart）约200-130 Ma和远端（Erzgebirge，
