This book was released on 1968 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two nearshore geophysical and geological surveys for the Rocksite Project off San Clemente Island, California, were made using continuous seismic profiling systems, geological diving, snapper sampling, and the CURV vehicle. Geologic interpretations are made relative to one of the surveys, a detailed survey off part of the west side of the island. A sequence of four sediment and rock units (A through D) is defined on the basis of the acoustical character and geometry of the acoustic reflection records. A north to northeast structural trend similar to that on the adjacent part of the island is mapped offshore. Some seaward pivotal faulting, not apparent from the island study, is suggested and appears partly responsible for the development of a submarine canyon located off Eel Point. Isopach maps of Units A, B, and C, and a structure contour map of Unit D tend to confirm this structural trend. A major unconformity is noted between Units B and C.A major insular terrace, at slightly over 100 meters in depth and prominent on the west side of the island, is postulated to have been wave-cut during Late Pleistocene to Recent time. This terrace has been affected by Recent tectonism. (Author).

This book was released on 1968 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: San Clemente Island has been studied to determine the geologic suitability of employing the island as a candidate site for the construction of a Rock-Site I installation, the land-linked experimental laboratory. The studies of the island consisted of a review of the geologic literature, aerial reconnaissance, geologic mapping, core drilling, borehole pumping, and offshore geophysical studies and sampling operations. Based on the results of these investigations the recommendation is made that the laboratory area beneath the sea floor be located off Mail Point with access tunnels to the laboratory originating at either Mail Point or Lost Point. As a candidate site, San Clemente Island is considered to be feasible but difficult. (Author).

Download or read book Engineering Geology of Rocks in Core Hole Eel Point San Clemente Island California written by D. L. Lamar and published by . This book was released on 1968 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 1,200-foot core hole drilled near Eel Point on the west coast of San Clemente Island, California, penetrated a homogeneous series of andesite flows varying in thickness from 11 to 169 feet. Petrographic examination revealed that textural variations within flows as a result of different cooling rates are more distinct than differences in composition between individual flows. Potassium-argon dates indicate that these flows were extruded in less than one-half million years during Miocene time. The flows are inferred to dip seaward at between 10 and 30 degrees. The rock will provide sound material for excavation. Problems of water leakage can be expected at faults and zones of decomposed rock. (Author).
