Progressive albitisation in the "Migmatite Creek" region, Weekeroo Inlier, Curnamona. [PDF]

open access: yes, 2009
Albitisation is pervasive and intense in the Curnamona Province. Most FeO-Cu-Au-U-REE deposits are associated with sodic alteration or albitisation (alkaline alteration) worldwide.

Experimental studies on geochemical cycling and mineralogical modifications during alteration of ultramafic lithologies in hydrothermal systems [PDF]

open access: yes, 2016
Hydrothermal alteration processes are key to the geochemical cycle between the oceans and the oceanic crust and also for mass transfer associated with subduction zone related environments.

The geochemistry and geomicrobiology of relict hydrothermal sulphide deposits

open access: yes, 2000
The diagenetic re-mineralisation of seafloor-sulphide deposits and the role of microbes in the metal-exchange processes were investigated in metalliferous sediments from the Alvin relict hydrothermal zone in the TAG area at 26º8'N (Mid-Atlantic Ridge ...

Characteristics Of Hydrothermal Alteration In Cijulang Area, West Java, Indonesia

open access: yes, 2015
Characterization of hydrothermal alteration in theCijulang area (West Java, Indonesia) was carriedout using shortwave infrared spectroscopy. Hydrothermal alteration in the Cijulang area occurs in the calc-alkaline volcanic and volcaniclastic rocks ...

Rare earth element systematics in ancient and modem hydrothermal systems

open access: yes, 1998
The geochemical significance of on-axis diffuse fluids, in addition to those formed during the waning phases of hydrothermal systems and off-axis crustal ageing processes, has been investigated through a comparison of the rare earth element (REE ...

Hydrothermal Alteration of the Saplica Volcanic Rocks, Sebinkarahisar, Turkey

open access: yes, 2001
A widespread, intense hydrothermal alteration zone has: developed in the Cretaceous Saplica volcanics as a result of the intrusion of Late Cretaceous-Paleocene granitoids. The propylitic, phyllitic (sericitic), and argillic alteration along with hematite,

The chemistry of iron in hydrothermal plumes

open access: yes, 2008
This thesis investigates the role of submarine hydrothermal vents in the global marine Febudget. While debate continues over the sources of dissolved Fe to the global deep-oceandissolved Fe budget, it had been presumed, until recently, that all the Fe ...

Lipid profiles of deep-sea organisms

open access: yes, 1998
Lipids are a group of biologically important compounds that may be used as indicators of relationships between an organism and its environment. Lipid class composition identifies types of storage lipid which can suggest a pelagic or benthic existence and
