Abstract
Remnants of a giant ophiolite nappe outcrop in the Central-East part o f Sulawesi. Although dismembered, the ophiolite displays all terms of a ''normal'' ophiolite including gabbros containing primary brown amph iboles. A 44 +/- 4 Ma isotopic age is estimated for their formation. T his age corresponds to that of formation of numerous Ante-Miocene fore -arc basins in this area. According to available palaeotectonic models , it is considered that the Sulawesi ophiolite formed at the eastern m argin of the Eurasian plate.
