Petrology of abyssal peridotites from the Gakkel Ridge, Arctic Ocean

Abstract

I report a characteristic of the petrography of a abyssal peridotite sample  from  Gakkel Ridge in this announcement. In the rare-earth element pattern of the monoclinal pyroxene, the flat pattern that the decrease in light rare earth element was not seen in was recognized. In this announcement, I argue about the variety of these patterns including result of mineral chemical composition in mylonite.
