文摘

The intrusion of less dense rock salt into denser overburden sediments can create salt diapirs. In the north of the Persian Gulf about 200 salt-gypsum domes are exposed, partially forming impressive salt glaciers. With the emergence of the salt domes exotic blocks of igneous and metamorphic rocks are also brought out to the surface. They are often intensively altered. Minerals, such as albite, quartz, hematite, coarse grained dolomite and apatite are widespread. The growth of blue amphiboles (magnesio-riebeckite) in veins of altered rocks indicate an intensive interaction of hydrothermal fluids with the host rocks in the salt diapirs.
