The supergene zone of the Cap Garonne mineral deposit (Provence, France) hosts one of the most remarkable mineralogy in the world with no less than 150 minerals, 16 of which are type locality. Such mineral diversity offers a detailed view of mineral and geochemical changes during weathering processes. The stratabound epigenetic primary mineralization occurs within a few meters-thick fluvial conglomerates resting above the Permian–Triassic transition and is probably related to Late Triassic–Early Jurassic hydrothermal events. The Cu–As mineralization in the lower part of the conglomerates is locally overlapped by a thin Pb–Zn-rich layer in the northern mine. The results show that the weathered part is significantly enriched in Cu, Pb, As, Zn, Ag, Ba, Sb, and Bi. The evolution of the supergene fluid is traced in an Eh–pH diagram by the succession of sulfides I (tennantite, galena), sulfides II (covellite), arsenates (olivenite), sulfates and sulfo-arsenates (brochantite, anglesite), and carbonates (malachite, azurite, cerussite). The primary sulfide oxidation acidified the host conglomerate and enabled the crystallization of secondary sulfides and arsenates. Efficient and rapid neutralization by the calcite cement of the host conglomerate and chlorite in the matrix caused successive precipitation of arsenates, sulfates, and carbonates. The supergene processes could be related to major periods of weathering in Western Europe (Early Cretaceous–Late Oligocene/Early Miocene). Erosion-prone periods may have contributed to the stripping of the Pb–Zn-rich layer in the southern mine.

加龙角矿床（法国普罗旺斯）的表生带是世界上最引人注目的矿物学之一，拥有不少于 150 种矿物，其中 16 种为典型产地。这种矿物多样性提供了风化过程中矿物和地球化学变化的详细视图。地层表观原生矿化发生在二叠纪-三叠纪过渡上方几米厚的河流砾岩内，可能与晚三叠世-早侏罗世热液事件有关。砾岩下部的铜砷矿化体与北部矿区的薄层富铅锌矿层局部重叠。结果表明，风化部分显着富集Cu、Pb、As、Zn、Ag、Ba、Sb、Bi。表生流体的演变在 Eh-pH 图中通过硫化物 I（铁锰矿、方铅矿）、硫化物 II（蓝铜矿）、砷酸盐（橄榄石）、硫酸盐和磺基砷酸盐（长铁矿、角铁矿）和碳酸盐的连续变化来追踪（孔雀石、蓝铜矿、白铅矿）。初级硫化物氧化酸化了主体砾岩并使得次级硫化物和砷酸盐能够结晶。主体砾岩的方解石胶结物和基质中的绿泥石的有效和快速中和导致砷酸盐、硫酸盐和碳酸盐的连续沉淀。表生过程可能与西欧的主要风化时期（早白垩世-晚渐新世/早中新世）有关。侵蚀多发期可能导致了南部矿区富铅锌层的剥离。
