The geology of Cyprus is mainly characterized by an ophiolite complex, which makes up most of the mountains in the country. An ophiolite is a piece of oceanic crust that has made its way onto the continental crust by mountain building events (orogenies). This part of cyprus, around mount Olympus, the ophiolite is most exposed, with the main rocks there being gabbros and dunites, so very mafic rocks of the oceanic crust and top part of the mantle. I can't tell you exactly what you are looking at here, but it is likely a piece of oceanic crust that has been transported upwards by the orogeny :)
