Analysis of Mn-deposits from the Pacific, supplement to: Grill, E V; Chase, R L; MacDonald, Richard Drummond; Murray, John W (1981): A hydrothermal deposit from explorer ridge in the northeast Pacific Ocean. Earth and Planetary Science Letters, 52(1), 142-150


Crusts composed of nontronite and ferromanganese oxides were recovered from Explorer Ridge, a spreading ridge segment in the northeastern Pacific Ocean located off the west coast of Canada. The chemical and mineralogical composition of the crusts closely resembles that of the mound-like hydrothermal deposits recently discovered at the FAMOUS site on the Mid-Atlantic Ridge and on the Galapagos spreading centre. Compositional anomalies suggest that the crusts are precipitates of hydrothermal vent solutions which were ejected discontinuously and subsequently mixed with seawater.
