Metasomatism in Iceland: Hydrothermal Alteration and Remelting of Oceanic Crust
1987The geochemistry of Icelandic volcanics, especially as pertains LIL-elements, RE-elements, and isotopes, has in the literature called for explanations involving heterogeneous mantle source. These explanations are shown to be incompatible with the data at hand.

The isocon diagram; a simple solution to Gresens' equation for metasomatic alteration
Economic Geology, 1986Gresens' (1967) method of analysis of changes in volume and concentrations during metasomatism have been applied in many studies of hydrothermal alteration. This paper provides a simple method of solution of Gresens' equations, for both volume (or mass) change and concentration changes, one which requires no significant manipulation of analytical data ...

Composition and volume changes accompanying soda metasomatic alterations, Västervik Area, SE Sweden
Geologische Rundschau, 1978Applying a set of equations derived byGresens (1967), composition-volume relationship are discussed for pairs of soda metasomatites and unaltered enclosing country rocks. A probable volume factor is inferred and the behaviour of elements interpreted. The metasomatic alteration was basically a process of leaching in which two stages can be recognized ...

Abstract The Olary Domain, part of the Curnamona Province, a major Proterozoic terrane located within eastern South Australia and western New South Wales, Australia, is an excellent example of geological region that has been significantly altered by metasomatic mass-transfer processes associated with regional metamorphism. Examples of metasomatically

Dolerite dykes that cut Tertiary baslats near the Skaergaard intrusion, East Greenland, are extensively altered to metasomatic assemblages indicating large scale mobilisation of calcium and alkalis. The alteration is characterised by replacement of the dolerite by prehnite together with lesser amounts of epidote, amphibole, salite, titanite, calcite ...

The Great Bear magmatic zone in the Northwest Territories of Canada contains large iron-oxide alkali alteration systems noted for having high potential for iron oxide-apatite, iron oxide-copper-gold, and affiliated ore deposits. Physical properties (density, magnetic, and electrical) were measured on 824 rocks samples selected to represent the range of

International Geology Review, 1967
This study is concerned with formation of minerals containing Li, Be, Cb, Ta, W, Bi, and other elements. The distribution of 35 accessory minerals was examined in biotite granite massifs occupying an area of 10 km2 . These minerals formed during the late magmatic stage and mainly during the subsequent metasomatic processes, such as rnuscovitization ...

Abstract Metasomatic rocks, in which mineralogical change is driven by infiltration of an externally-derived fluid, are challenging for the application of equilibrium thermodynamics because fluid-driven changes in rock bulk composition can be faster than diffusive within-grain re-equilibration.

Petrographic and geochemical study of 79 samples from the Limestone Caribbee islands of Antigua, St. Martin and Desirade show different degrees of metasomatic alteration resulting from burial metamorphism up to lower zeolite facies (with laumontite and prehnite).
