Summary:Veins are a ubiquitous feature within the Corsican Ophiolite and attest to the production and movement of fluids at all metamorphic grades. However oxygen isotope data for the ophiolite indicates that there has been little fluid flow between different units of the ophiolite. In contrast, oxygen and carbon isotope data for matrix and vein calcite in the ophiolite suggest that the calcite is probably derived from CO2-bearing fluids from the surrounding Schistes Lustres. There does not appear to be any fluid flow in the opposite direction, from the ophiolite to the Schistes Lustres. Thus, whilst large-scale fluid flow from the Schistes Lustres to the ophiolite probably occurred, this fluid flow was not pervasive. The disequilibration between the calcite and the whole rock suggests that fluid flow may have been rapid or confined to fracture systems. Abstract Copyright (2000) Elsevier, B.V.
