Bowlingite - Ca_0,25(Mg,Fe)₃((Si,Al)₄O₁₀)(OH)₂* nH₂O

Bowlingite is an obsolete name for saponite (from Latin, "sap" = soap, alluding to its greasy or soapy feel and appearance). Bowlingite is a mixture of smectite, quartz, chlorite, serperntine, talc. The formation of iddingsite or bowlingite depends on O₂ fugacity.
