geochemistry of hydrothermal ore deposits pdf

Two newly discovered hydrothermal vent fields of the Wallis and Futuna region, Kulo Lasi and Fatu Kapa, were sampled for fluid geochemistry. A great geochemical diversity was observed and assigned to the diversity of lithologies as well as the occurrence of various processes. Kulo Lasi fluids likely formed by interaction with fresh volcanic rocks, phase separation, and mixing with magmatic fluid. Both deposits show a pronounced positive Eu anomaly and the light REE enrichment which are characteristic of the high-temperature fluids venting from sediment-free oceanic ridges. Whilst the Okinawa Trough REE data are unique in the hydrothermal vent systems in having a flat chondrite-normalized pattern for the REEs heavier than Tb. 110 C.A.

During processing the most of Au, Ag, Se, Te, Pb, Bi, Sb, Hg as well as notable part of Cu, Zn and Cd fail for tailings and became heavy metal pollutants. Modes of occurrence of hydrothermal vent fields (Fig. 1(a)) have been found and intensively investigated using research vessels and submersibles since 1986 (e.g., Sakai and Nozaki, 1995). The purpose of this paper is to present the rare earth element (REE) patterns of hydrothermal deposits and a Calyptogena shell from one of the active vent fields, the Iheya Ridge Ore and gangue minerals of seafloor hydrothermal deposits in the Mariana Trough Chihomi Iwaida* and Hirotomo Ueno** Abstract Chimney and mound samples collected by “Shinkai 6500” from two hydrothermal vent fields in the Mariana Trough were studied mineralogically and geochemically.

Two active hydrothermal fields, Jade and Hakurei fields have been discovered within the Izena Hole, a rectangular 6 km × 3 km shape depression located in the middle Okinawa Trough back arc basin. In both fields, intense hydrothermal activity is represented by venting of high-temperature fluid (>300°C) and occurrence of sulfide/sulfate ore deposits. 01.07.2001 · adshelp[at]cfa.harvard.edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A Ore genesis of hydrothermal ore deposits in the Jungwon district.

Other deposits may be incorporated into the study where suitable material and deposit understanding is available. This project is primarily concerned with modelling the fluid flow and metal deposition through space and time associated with Irish-type Zn-Pb deposits, and to determine how these techniques could be deployed in geochemical exploration to vector towards Irish-type orebodies. Geothermal systems occur in a range of crustal settings. The emphasis of this review is on those occurring in regions of active or recently active volcanism, where magmatic heat at depths up to 8 km leads to convection of groundwater in the upper crust. Hot water (and steam) flows are controlled by the permeability of the crust and recent data have emphasised the dominance of secondary ... Epigenetic, N-S, NNE-SSW quartz veins crosscut metapelites and metagabbro in Maru area. The objectives of this work were to study field, mineralogy, and geochemical characteristics of gold bearing quartz veins and soils. Euhedral and polygonal magnetite with hematite constituted the major ore minerals. Quartz occurred as main gangue phase with appreciable sericite and chlorite.
