System:TrigonalColour:colorless, white
Member of:Whitlockite Group
Name:Named for George P. Merrill (1854-1929), Curator of Geology, U.S. National Museum (Smithsonian Institution) by Wherry (1917)


Whitlockite Group. Mg-dominant analogue of Ferromerrillite.

Merrillite was revalidated as a valid species in 1976.
Merrill (1915) described the mineral from (at least) 4 meteorites, which may be considered type localities: Alfianello, Dhurmsala, Pultusk, Rich Mountain.

All reported non-terrestrial 'whitlockites' are actually merrillite.
