Abstract

The metamorphic rocks from Morille-Martinamor area (quartz-feldspathic , aluminous, calc-silicate, migmatic and cataclastic rocks) are varied ; the geochemical and mineralogical features allow to found a sedimentary origin with possible and variable acid calcoalkaline contribution for some groups, without orthoderived characteristic for the studied calc-silicate levels. The granites mainly are linked to the typical traits of leucocratic range, which are generated by crustal anatexis, and they are grouped without strong differences. The orthogneiss are older and show a typical behaviour, fairly placed between the two groups.
