Tbs aajor crystelliat component Is KC1 vlth possibly a snail anount of SsCl sad sons unidsstifisd material. This sample is approximately 1000 crystalline. The crystalline portion of the saaple is made up of 3 parts CaCQs to about 1 part Ca silicate. The exact chemical formula for the silicate could not be determined. The best agreement vlth ths data uas given toy 3Ca0*26i0i and 72Ca0*B10fc. Sample IHF-Feldspar ^lOm., F-BOflO. Ths diffraction diagram of this saaqile agrees exactly vlth the data given in the Eanavalt card fils for aicrocllne feldspar (card 1-07D5).
