Numerical Modeling of Structurally Controlled Ore Formation in Magmatic‐Hydrothermal Systems
Geochemistry, Geophysics, Geosystems, Volume 23, Issue 8, August 2022., 2022 Abstract Faults and fractures can be permeable pathways for focused fluid flow in structurally controlled ore‐forming hydrothermal systems. However, quantifying their role in fluid flow on the scale of several kilometers with numerical models typically requires high‐resolution meshes. This study introduces a modified numerical representation of m‐scale

Geofluids, Volume 2022, Issue 1, 2022., 2022 The Roc Blanc Pb‐Zn‐Ag‐Au vein deposit is located in the NW of Marrakech, in the Central Jebilet massif. It is spatially related to Bramram‐Tabouchennt‐Bamega (BTB) granodioritic pluton (ca. 330 Ma) metamorphism aureole. The main veins hosted in black shales are oriented N‐S to NNW‐SSE. Pb‐Zn‐Ag‐Au ore is associated with quartz, chlorite, sericite, and
