Abstract

Fluorite samples collected at Jbel Tirremi and Koudiat Titeft, near Taourirt contain abundant secondary fluid inclusions which recorded various T and P information during the burial and subsequent uplift of these extrusions. The oldest inclusions are grouped along heterogeneous families with CO <sub>2</sub> -bearing inclusions and halite-bearing ones in the same healed cracks. The minimum trapping temperature is 160 degrees C. Two independent geobarometers indicate trapping pressures higher than 0.5 Kb, implying a minimum burial of 3 to 4 km. Later epirogenesis, possibly related to deep faulting and associated halokinesis brought these structures to outcrop, probably from Miocene to present.
