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 fractionation of carbon and magnesium isotopes is a potentially useful tracer natural weathering in ultramafic catchments engineered CO2 storage. To evaluate the use as tracers storage, we assessed isotope between hydrous Mg-carbonate minerals fluid during mineral phase transformation from nesquehonite [MgCO3·3H2O] to dypingite [Mg5(CO3)4(OH)2· ? 5–8H2O], two common products rock weathering...

The so-called hyperaccumulator plants are capable of storing hundred or thousand times bigger quantities heavy metals than normal plants, which makes hyperaccumulators very useful in fields such as phytoremediation and phytomining. Among these there many serpentinophytes, i.e., that grow exclusively on ultramafic rocks produce soils with a great proportion metals. Even though multiple classific...

Abstract Cratonic lamproites are diamondiferous ultrapotassic rocks that emplaced through thick continental lithosphere and thought to derive from melting of metasomatized (i.e., geochemically enriched) regions the subcontinental lithospheric mantle (SCLM). We explored alternative hypothesis melts sourced sublithospheric convective mantle) sources dominate genesis cratonic lamproites. Supportin...

To provide new insights into the evolution of kimberlitic magmas, we have undertaken a detailed petrographic and mineralogical investigation highly evolved carbonate–phlogopite-bearing kimberlites Kepino cluster, Arkhangelsk kimberlite province, Russia. The are represented by volcanoclastic breccias massive macrocrystic units within pipes as well coherent porphyritic sills. from similar in petr...

mineral paragenesis of rodingitized basic rocks of iranian ophiolites are presented and metasomatic reactions between ca+2 bearing aqueous fluids issued during serpentinization of host ultramafic rock – with magmatic minerals of basic rocks leading to present paragenesis of rodingites are discussed. it is concluded that ca+2 rich aqueous fluid in equilibrium with serpentinite has high ca+2 chem...
