The source of metals involved in the formation oceanic ultramafic-hosted hydrothermal Cu-Fe-Co-Zn-Ni mineralization remains poorly constrained. Here, we focus on a fossil mineralized system preserved Platta nappe (SE Switzerland), where mantle rocks were exhumed along detachment faults to seafloor during Jurassic rifting. mineralization, associated with Fe-Ca-metasomatism (ilvaite-hydroandradit...

The Niukutou Pb-Zn deposit is typical of skarn deposits in the Qimantagh metallogenic belt (QMB) East Kunlun Mountains. In this study, based on detailed petrographical observations, electron microprobe analyses (EMPAs), and laser-ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) analyses, we report major trace element compositions mineral assemblages (garnet, pyroxene, ilvaite, ...

Secondary minerals occur within the tholeiitic basalts of Salsette Island in greater Mumbai region, as well other localities Deccan Volcanic Province (DVP). However, secondary show remarkable differences with respect to their mineral speciation and precipitation sequence, which are both due unique geological environment. The region is built up by subgroup, represents youngest sequence DVP. It f...
