Description
Summary:is a steeply-dipping linear belt 90 km long by 1 to 5 km wide containing a variably disrupted ophiolite suite and other mainly mafic volcaniclastic and volcanic rocks that originally overlay the ophiolite complex. The ophiolite complex closely resembles others interpreted as samples of oceanic crust and upper mantle, although the thickness of the gabbro layer is less than 1 km. The overlying mafic volcaniclastic sediments show evidence of deposition close to (and locally at) the base of a steep scarp bounding the east side of the basin. Minor silicic tuffs are found near the top of the preserved sequence. Mafic pillow lavas comprise from 0 to 80% of the sediment section whose total preserved thickness before deformation is estimated as 5 km.
