Outline of Final Research Achievements

The V3 Volcanic rocks of the Oman Ophiolite are thick submarine lava flows exceeding an estimated volume of several cubic kilometers. The V3 flow field consists of massive cores sandwiched between columnar jointed lava crusts. The V3 flow is divided into the Upper and the Lower flow by the intervening pillow lava and shale. Yb variation of the lower flow is consistent with the internal growth of inflating sheet where newly supplied lava was injected into the core of the flow, whereas the upper flow was empalced lobe by lobe one after the top of the other, which were welded togher to form a massive sheet-like lava.
