Ferromagnesian minerals are usually dark in color and have relatively high specific gravities (greater than 3.0). Common rock-forming mafic minerals include olivine, pyroxene, amphibole, biotite mica, and the plagioclase feldspars.

Common non-ferromagnesian minerals include quartz, orthoclase feldspar, muscovite mica, and also some plagioclase feldspar.

Do you have a list?

A ferromagnesian mineral has iron (ferro) and magnesium (magnesian) in it. If it does not have these it is not a ferremagnesian mineral. Lots of minerals fall into this category.
