1. 1. Fluid-induced alteration of metasedimentary rocks in the Scottish Highlands

   Författare :Alexander Lewerentz; Alasdair Skelton; Patrick Crill; Charlotte Möller; Jay Ague; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metamorphic fluids; metamorphic fluid flow; fluid-rock interaction; metamorphic fluid fluxes; Geology; geologi;

   Sammanfattning : Fluids, mainly H2O and CO2, are released from H- and C-bearing phases during prograde metamorphism. Because of the buoyancy of these fluids, they rise within the crust towards the surface of the Earth. Metamorphic fluids take advantage of permeable horizons, shear zones, fold hinges, fractures, and are channelled into high-flux zones. LÄS MER

3. 2. Vein controlled crystal size distributions of Barrovian index minerals

   Författare :Alexander Lewerentz; Alasdair Skelton; Uwe Ring; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The concept of index mineral based metamorphic zones was first introduced by George Barrow in 1912, and Barrovian metamorphism is still applied by metamorphic petrologists. Today the importance of metamorphic fluids for driving metamorphic reactions is widely recognised. LÄS MER
