Experimental petrological constraints on the origin of mantle-derived magmas
As direct products of mantle melting,mantle-derived magmas faithfully record the chemical composition and properties of the mantle source region.Their compositions and properties can be used to reveal their evolution processes,and to provide important information for deeply understanding dynamic processes and evolutionary history of the Earth's interior.Recent advancements in high-temperature high-pressure experimental apparatus and microanalytical techniques have significantly enhanced our capacity to simulate and document the physicochemical reactions of mantle rocks under the high-temperature high-pressure conditions.By delicately controlling experimental conditions and starting material compositions,we can assess the mechanism of partial melting of the mantle in different geological settings,thereby constraining the formation and evolution processes of mantle-derived magmas.In this paper,I have systematically reviewed the experimental petrological investigations pertaining to the genesis of different mantle-derived magmas,and have summarized the status,outstanding progress and persisting challenges in three related experimental research fields including the melting process of single mantle peridotite source,the melting of other rock types within the mantle source,and the hybridization melting of different rocks in the mantle source.Furthermore,considering the future direction of deep Earth science,the paper proffers a prospective outlook on the experimental frontiers concerning the origin of mantle-derived magmas and the crust-mantle interaction.
