Petrology and geochemistry of the metasediments of the janub metamorphic suite, southern jordan : implications for geothermobarometry and economic potential

الملخص EN

Petrographical and geochemical characteristics of the hornfelses and metaconglomerates of the Janub metamorphic suite have been examined to reveal their geothermobarometry and economic potential.

The temperature of metamorphism attained by hornfelses ranges between 500oC and 545 ˚C with an average temperature of 522˚C, while metaconglomerate may show a wider press lower abund Keywords: Arabian-Nubian Shield; Janub Metamorphic Suite; Hornfelses; Metaconglomerates; Mineral Chemistry; Geothermobarometry.

range between 300 ˚C to 600 ˚C with an average temperature 520 oC.

Mineralogy of the metasediments indicates a low ure type of metamorphism (< 4 Kbar).

These conditions correspond to metamorphism equivalent to upper greenschist to amphibolite facies.

The identified opaque minerals are ilmenite, magnetite and titanomagnetite.

Sulphides are less antand include pyrite, cinnabar, pyrrhotite, sphalerite, galena and chalcopyrite.
