What is ‘Boninitic’ clasts from the Mesozoic olistostromes and turbidites of Angelokastron (Argolis, Greece) about?

The Lower Unit of the ophiolitic sequence of Northern Argolis comprises turbiditic sediments and olistostromes. both containing ophiolitic clasts. mainly crystal fragments (clinopyroxene. plagioclase. Cr-spinel, amphibole) in the turbidites and cumulitic intrusives (quartz noritic amphibole-bearing gabbros). subvolcanic rocks (dolerites) and various effusive lithologies (mainly Si-rich basalts to basaltic andesites) in the olistostromes. The volcanic rocks belong to three groups. In rare cases the lavas are niineralogically and chemically comparable with MORB; most of them. and the subvolcanic rocks, contain primary quartz and amphibole, orthopyroxene, Ca-rich plagioclase and clino-pyroxene\_+ Cr-spinels. All rocks are Si-and Mg-rich and have high concentrations of 'compatible' and very low concentrations of 'incompatible' elements. The REE profiles are characteristically U-shaped. Many of the observed features are comparable with those of suhduction-related lavas and, in particular, with present day boninites and ophiolitic boninitic rocks. The gabbroic rocks have mineralogical and chemical analogies with the dolerites and lavas, thus it may be argued that the gabbros represent th
