ⓘ Ankerite ?
Formula: Ca(Fe2+,Mg)(CO3)2
Description: A note on ankerite: Recent redefinitions of the ankerite-dolomite series mean that many samples that would have been classified as ankerite would now be defined as dolomite (iron-rich dolomite) and true ankerite is quite rare. See a discussion here https://www.mindat.org/mesg-7-430792.html . The listing below reflects the current species definitions.
