Chalcophile elemental constraints on sulfide-saturated fractionation of Cenozoic basalts and andesites in SE China

Cenozoic volcanic rocks are widespread in eastern China. These rocks have variable isotope compositions, reflecting different mantle sources under SE and NE China. In order to explore their PGE variations, chalcophile elements are determined for basalts from Leiqiong and Sanshui and andesites from L...

Description
Summary:Cenozoic volcanic rocks are widespread in eastern China. These rocks have variable isotope compositions, reflecting different mantle sources under SE and NE China. In order to explore their PGE variations, chalcophile elements are determined for basalts from Leiqiong and Sanshui and andesites from Lianping in SE China. Basalts from Leiqiong have higher Ni (66–376ppm) and Cu (30–73ppm) contents than those from Lianping and Sanshui. All the samples have extremely low PGE contents, low Cu/Zr (
