Abstract

Leucogabbros of Kettara suffered combined effects of hydrothermal alteration and compressive strain during magma cooling. Slightly deformed zones are characterized by low element mobility and superimposed static paragenesis which began in amphibolite facies and finished in prehnite-actinolite facies. Alteration within strongly deformed zones is marked by high element mobility and chloritoschist development in prehnite-actinolite facies. Transformation of leucogabbros and formation of adjacent sulfide deposits can be linked to equivalent hydrothermal fluids.
