Geology of borabora. By j. t.

Stark and A. L. Howland. Bernice P. Bishop Museum Bulletin 169, 43 pages, 4 plates, 10 figures, 1941. Discusses the location, topography, history, physi ography, vegetation, and geology of this volcanic island in the Society Group.

Gives an outline geologic map. The

sequence of events in the geologic history is interpreted as follows: A cone was formed of successive flows of lava, the relatively high gas content of which pro duced extreme vesicularity and pillow struc tures. The cone above sea level is believed to have been built in Late Pliocene or Early Pleis tocene. The magma in the central vent sub sided and the porous lavas cooled fairly rapidly, as a result of which radial joints or Assures developed in the crater walls, with vertical planes of weakness that extended for consider able distances out into the lava cones. New

magma surged into these vertical cracks, re sulting in intrusions of vertical porphyry dikes along radial joint planes. This was repeated several times, allowing at least four periods of olivine porphyry dike intrusion. These were followed by a less extensive intrusion of non porphyritic, basaltic dikes. After this the western side of the cone down-faulted, forming the large western lagoon, the western rim be ing preserved only in the small remnants re presented by Toopua and Toopua Iti. The period down to the present time has seen erosion, subsidence, and reef building, inter rupted by the recent fall in ocean level of approximately six feet, recorded by marine benches,
