Named in honor of Dr. Joseph Anthony Mandarino who was a Canadian-American mineralogist and Emeritus Curator of Mineralogy at the Royal Ontario Museum in Toronto, Canada where some of the type material for this mineral is hosted. Mandarinoite is a rare mineral that can be found in Bolivia, the United States, Honduras, Cyprus, Italy, as well as in newer localities in Australia, Bolivia, and China. It occurs from the simultaneous ozidation of penroseite and pyrite in a selenium-bearing ore deposit.

Named for the manganese in the chemical composition and for its relationship to babingtonite. Manganbabington can be found in localities in Russia, the United States, Japan, and China. It is a rare mineral that occurs at its Russian locality in thin stringers in an amphobolized garned-pyroxene-magnetite skarn that is associated with an iron deposit, and at its US locality as replacing hedenbergite-johannsenite skarns.

Named as being the manganese analogue of gordonite. Mangangordonite is a rare mineral that occurs as a secondary mineral in granite pegmatites. It can be found in localities only in the United States, Russia, and Germany. Associated minerals include Jahnsite, beraunite, strunzite, strengite, spodumene, quartz, muscovite, fluorapatite, tourmaline, and siderite.
