Endolithic Colonization of Fluid Inclusion Trails in Mineral Grains

Endoliths in sandstones: Many scenarios for the colonization of planetary surfaces by microbial life involve endoliths [1, 2]. The need to avoid the damaging effects of ultraviolet radiation makes colonization of the immediate sub-surface desirable, particularly at an early stage of evolution before screening pigments have been developed [3, 4]. Minimal (millimetreto sub-millimetre-scale) penet...

Mineral chemistry and thermobarometry of amphibolites from the Qotur metamorphic complex (West Azerbaijan Providence, NW Iran)

The Qotur metamorphic complex consists of metabasites, gneisses, marbles and calc-silicates as well as serpentinites which is cropped out at the west border of West Azerbaijan and Turkey. The amphibolites from the Qotur metamorphic complex can be classified as two types of ortho- and para-amphibolites. Minerals in this ortho-amphibolite are hornblende, plagioclase, zircon, titanite, and opaque ...

Low-temperature fluid flow through sulfidic sediments from TAG: modification of fluid chemistry and alteration of mineral deposits

Low-temperature fluid flow has been identified as an important component of the heat, mass and chemical flux at sites of active venting. One way to study the movement of water through hydrothermal deposits is to analyse the pore-fluids extracted from sulfidic sediments. The composition of diffuse flow fluids in one sediment core from the south of the active TAG mound reflects the dilution of hi...

Mineral chemistry of magnetite and fluid inclusions studies in the Kuh-Baba iron deposit, south of Hashtroud, NW Iran

The Kuh-Baba iron ore deposit is located about 70 km south of Hashtroud, East-Azarbaidjan Province, NW Iran. The deposit is genetically affiliated with intrusive bodies of gabbroic to dioritic composition. The principal host rocks for the Fe mineralization include units of gabbro-norite and pyroxene hornblende gabbro-norite. The widespread alteration zones which are accompanied with Fe-minerali...

Petrography, mineral chemistry and thermobarometry of amphibolites from the Allahyarlu metamorphic complex -Ardebil, NW Iran

The pre-Eocene Allahyarlu ophiolitic- metamorphic complex is exposd in the core of the Allahyarlu anticline in the northwest of Iran and northeast of Meshginshahr. This complex consists of a variety of schist, gneiss, amphibolite and metadibase rocks with serpentinite and tectonic slices including gabbro, dunit, marble and diabase. Amphibolites can be divided into garnet-free amphibolite and ga...
