Overview

Magnesiohastingsite is a calcium-containing amphibole and a member of the hornblende group. It is an inosilicate (chain silicate) with the formula NaCa2(Mg4Fe3+)(Si6Al2)O22(OH)2 and molar mass 864.69 g. In synthetic magnesiohastingsite it appears that iron occurs both as ferrous iron Fe2+ and as ferric iron Fe3+, but the ideal formula features only ferric iron. It was named in 1928 by Marland P. Billings. The name is for its relationship to hastingsite and its magnesium content. Hastingsite was named for the locality in Dungannon Township, Hastings County, Ontario, Canada. Calcic (containing calcium) amphiboles include:

The tremolite – actinolite – ferro-actinolite series The hornblende group The kaersutite – ferro-kaersutite series Joesmithite The hornblende group includes:

The edenite – ferro-edenite series The tschermakite – ferrotschermakite series The pargasite – ferro-pargasite series The magnesiohastingsite – hastingsite series The magnesiosadanagaite – sadanagaite series
