Ferro-actinolite is the ferrous iron-rich endmember of the actinolite-tremolite continuous solid solution series of the double chain calcareous amphibole group of inosilicate minerals. All the series members belong to the monoclinic crystal system.
The following formula comparison indicates the position of individual well-known members within the series: tremolite: ☐Ca2(Mg5.0-4.5Fe2+0.0-0.5)Si8O22(OH)2 actinolite: ☐Ca2(Mg4.5-2.5Fe2+0.5-2.5)Si8O22(OH)2 ferro-actinolite: ☐Ca2(Mg2.5-0.0Fe2+2.5-5.0)Si8O22(OH)2
