- W2181870086 abstract "The relatively fresh basement basaltic rocks cored at Sites 794 and 797 during ODP Legs 127 and 128 show compositional variations suggesting the following: (1) the aphyric rocks might be differentiated from compositional equivalents of the aphyric sample with the lowest FeO*/MgO (Sample 127-797C-12R-4, 35-37 cm); and (2) the plagioclase-phyric rocks (i.e., another constituent of the basement basaltic rocks from the sites) may be derivatives from the same parents; in this case, however, crystallized plagioclase was not effectively removed. Melting experiments were conducted for Sample 127-797C-12R-4, 35-37 cm, and the differentiation processes for the basement basaltic rocks were assessed. The high-pressure melting-phase relation can not account for the compositional variation of the aphyric rocks, suggesting that the variation was developed at relatively low pressure where olivine and plagioclase fractionation was followed by Ca-rich clinopyroxene fractionation. The density of Sample 127-797C-12R-4,35-37 cm, is comparable to that of plagioclase at some depth, but at still relatively low pressure, making it possible that the liquidus plagioclase was retained in the successive liquids to produce the plagioclase-phyric rocks. According to backtrack calculation assuming the olivine maximum fractionation, Sample 127-797C-12R-4, 35-37 cm, was differentiated from primary picritic high-Al basalt magma. The estimated primary magma composition was experimentally proved to coexist with harzburgite mantle at about 14 kbar, suggesting relatively shallow production (approximately 40-50 km below surface) of the rifting-related primary magma." @default.
