DOI: 10.1016/j.fuel.2019.116964
Abstract: Abstract Ash fusion temperatures (AFTs) are widely used for evaluation of fusibility of coal ash for combustion and gasification. K2O and Na2O is regarded as the effective component to enhance the ash fusibility for slag… read more here.

DOI: 10.1016/j.lithos.2020.105570
Abstract: Abstract The chemical composition of the upper continental crust (UCC) dramatically changed from predominantly sodic to more potassic during the late Archean (3000–2500 Ma), although how this change occurred remains poorly constrained. The origins of Neoarchean… read more here.

DOI: 10.2138/am-2020-7403
Abstract: Abstract Sedimentary diapirs can be relaminated to the base of the lithosphere during slab subduction, where they can interact with the ambient lithospheric mantle to form variably metasomatized zones. Here, high-pressure experiments in sediment-harzburgite systems… read more here.
