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...

The Avalon Peninsula on the island of Newfoundland, Canada, defined as type zone Avalonia, is believed to have been impacted by several orogenetic and deformation events since Neoproterozoic. Previous studies determined that lowest degree metamorphism reached in successions was prehnite–pumpellyite or greenschist facies. We sampled measured 13 mainly clastic sedimentary sections ranging from la...

This paper is the first attempt to study mineralogical and geochemical features of mineralization hosted within volcanic rocks Baska Piwaza section, at Halgurd Mountain, which highest mountain in Kurdistan whole Iraq. The host lithologies studied section represent mostly (basalts andesites), secondary sedimentary lithologies, such as radiolarian chert. There are two main stages oxide sulfide th...
