Tbs major crystelliat component Is EDI vlth possibly a snail amount of EaCl sad sons unidsstifisd material. - This sample is approximately lOOJt crystalline. The crystalline portion of the saaple is made up of 3 parts CaCOs to about 1 part Ca silicate. The exact chemical formula for the silicate could not be deteruined. The best agreement vlth ths data uas given toy 3Ca0*26i0i and 72Ca0*B10fc. Sample IHF-Feldspar \10m., F-BOflO. - Ths diffraction diagram of this saaqile agrees exactly vlth the data given in the Eanavalt card file for aicrocllne feldspar (card 1-0705).
