文摘
- •
Peridotite xenoliths in the Datong Quaternary alkaline basalt are studied.
- •
In-situ analysis of clinopyroxenes in the peridotite xenoliths indicates carbonatitic metasomatism.
- •
Agent for carbonatitic metasomatism was derived from subducted carbonated pelite.
- •
Subduction of the Paleo-Asian oceanic plate could have contributed to the carbonatitic metasomatism.
