Comments on the geologic information

  • Geologic Description = Three lenses and a few small veins of quartz, cutting Cretaceous metasedimentary rock, are exposed on the beach along a narrow lagoon. One lens on the west side of the lagoon ranges from 3 to 10 inches thick and is exposed for 200 feet. It strikes N. 75 W. and dips 85 south. Four parallel quartz stringers dip towards the vein at a distance of 50 to 100 feet. A second lens, located at the south end of the lagoon is 26 to 30 inches in thickness. It strikes N. 65 E. and dips 71 north. The third lens, located on the west side of the lagoon is 6 feet in thick and can be traced for 300 feet. The lens strikes N. 70 E. and dips 73 north. These lenses and stringers were sampled by Roehm (1936, PE 131-4) and assayed only trace amounts of precious metals.
