Very large amounts of quartz was found in the Inamine series but small amounts of feldspar was also found in this soil series. 2)The secondary minerals of the Nakagawa, Gushiken, and Itosu serieses were mica-vermiculite nterstratified layer, kaolinite and gibbsite. Mica-vermiculite interstratified layer of the Nakagawae and Gushiken serieses was predominantly vermiculite, especially in the Gushiken series but that of the Itosu series was the mixture of about the same amounts of both minerals. The secondary minerals of the Inamine series were montomorillonite, mica, and kaolinite., 論文}, pages = {37--41}, title = {X-線回折分析による沖縄本島主要土壤統の一次鉱物と粘土鉱物の同定}, volume = {7}, year = {1968} }
