How does a cratonic sequence form? Sea level rising and then falling, thereby depositing layers of sediment onto an area of ancient rock called a craton. Each one represents a time when epeiric seas deposited sediments across the craton, while the upper and lower edges of the sequence are bounded by craton-wide unconformities eroded when the ...We report new textural and chemical data for 10 garnet peridotite xenoliths from the Udachnaya kimberlite and examine them together with recent data on another 21 xenoliths from the 80–220 km depth range. The samples are very fresh (LOI near zero), modally homogeneous and large (>100 g). Some coarse-grained peridotites show incipient stages of …
