21. Pillow lava is abundant along the bases the flows, some of which are underlain by hyaloclastite breccia.22. Above the pillow lava units lies a layer of ferromaganiferous mudstones and clastic volcanics ( the epiclastics ). 23. The cold water quickly solidifies the lava, producing the pillow lava that is typical of underwater volcanic activity. 24. Alexander S . Lloyd, a student of Dickinson College, focused on the cooling rates of pillow lavas . 25. The lowest units of the ophiolite are the Lower Pillow Lavas , controversially separated from the Upper Pillow Lavas. 26. The lowest units of the ophiolite are the Lower Pillow Lavas, controversially separated from the Upper Pillow Lavas . 27. An isolated pile of subaerial basalt flows and associated pillow lava rest on varved clay and till in King Creek. 28. Pillow lava is rounded balls of lava that was given very little time to cool due to immediate exposure to water.29. Malpelo Island is composed of Miocene pillow lavas , volcanic breccias, and basaltic Nazca Spreading Centre and the Gal�pagos hotspot. 30. Its geology consists of the Batalha rock formation which includes its ocean crust, its rocks originated from tholeitic pillow lava .
