DOI: 10.2138/gselements.13.6.380
Abstract: Layered intrusions are important for a number of reasons. Primarily, they present a record of how mafic magmas crystallize and, as a con sequence, change their compositions by the process of magmatic dif ferentiation. However,… read more here.

DOI: 10.25131/sajg.125.0001
Abstract: A recent re-interpretation of the Bushveld Complex and other layered intrusions as stacks of randomly emplaced, amalgamated sills is mostly fuelled by finding of zircon ages that are not getting progressively younger from the base… read more here.

DOI: 10.3390/min13050597
Abstract: Large-scale layered intrusions of a peridotite–pyroxenite–gabbronorite complex, to which Cr, Ni, Cu, and PGE deposits and ore occurrences are confined, were emplaced into the Baltic paleocontinent 2.50–2.45 Ga. Layered intrusions in the Monchegorsk Ore District,… read more here.
