Metalliferous Deposits within Newfoundland Ophiolite Complexes
Abstract
Because of their apparent metalliferous concentrations, six metamorphosed sedimentary rocks were collected from the island of Newfoundland. The samples were studied in order to determine the origins of the metals contained within. X-ray diffraction, atomic absorption, and thin section work revealed a hydrothermal origin. Through comparison to metalliferous sediments found in active spreading centers, a similar origin for the samples was concluded. The metals are the result of precipitation from fluids which were heated by, and reacted with, oceanic lithosphere which was still cooling at that time.
