Geochemistry and mineralogy of sediments from southeast Explorer Rift (50 N, 130 W), northeast Pacific : in search of evidence of hydrothermal activity Hansen, Kenneth Frederick
Abstract
The composition of sediments in a portion of Explorer Spreading Centre, Explorer Deep, is examined. Clay mineral, bulk mineral and chemical compositions (Al, Ba, Ca, CI, Co, Cu, Fe, K, Mg, Mn, Ni, P, Si, Na, Ti, Zn) of hemipelagic sediments on the floor of Explorer Deep are compared to those on adjacent flanks, and to Explorer Deep metalliferous sediment, to determine the extent of hydrothermal mineral formation. Explorer Deep hemipelagic sediments are composed of quartz, opal, feldspar, amphibole, carbonate, phyllosiIIcates, iron and manganese hydroxides,illmenlte, rutile and hematite. Individual phyllosiIlcates have distinct size-distributions; fine clay (
