Within many existing concepts, which are in a focus of this workshop, there is one suggesting that some portion of chromitites originate from deep mantle,展开更多

The basic principal of FIB is using accelerated Ga-ions to sputter material from a target. At the beginning of FIB application in Geosciences it was utilized as a tool to prepare site-specific samples for transmissionelectron microscopy （TEM）.展开更多
