Boninites翻译
WebJan 1, 1989 · Boninites are classified, based on their major element systematics, into low-Ca (CaO/Al 2 O 3 < 0.75) and high-Ca (CaO/Al 2 O 3 > 0.75) [110]. The Cape Vogel in … Boninite is an extrusive rock high in both magnesium and silica, thought to be usually formed in fore-arc environments, typically during the early stages of subduction. The rock is named for its occurrence in the Izu-Bonin arc south of Japan. It is characterized by extreme depletion in incompatible trace elements that are not fluid mobile (e.g., the heavy rare-earth elements plus Nb, Ta, Hf) but variable enrichment in the fluid mobile elements (e.g., Rb, Ba, K). They are found al…
