Abstract

The Jandaq ophiolite
has suffered different types and phases of metamorphism. In this ophiolite,
gabbroic dikes and plugs cross cut the mantle peridotites. Minerals of metagabbros
are clinopyroxene, amphibole, plagioclase, titanite, prehnite, epidote,
magnetite and calcite. Joints and cracks of gabbroic intrusions are filled by hydrothermal
minerals. These hydrothermal veins are consist of clinopyroxene, garnet,
epidote, prehnite, chlorite and calcite, and are light in hand specimen.
