The Paramirim Aulacogen was filled by the Espinhaço and São Francisco supergroups in period from 1.75 to 0.69 Ga, suffered partial inversion during Ediacaran. In northern sector of intracontinental domain Araçuaí-WestCongo Orogen, six compressive deformational phases were interpreted associated with frontal Aulacogen. Three structural domains identified: Jacaraci Fold-Thrust Belt, Caetité Nappe...

Metamorphic Core Complexes (MCCs) form when a thickened domain with a low-strength lower crust is submitted to extension. These structures are characteristic of post-orogenic extension, and field observations suggest that several MCCs rework a crustal nappe-stack emplaced before extension begins. These MCCs therefore develop within heterogeneous crusts that contain pre-existing dipping heteroge...

The area between the villages of Reka in Idrijca Valley, Bukovo and Zakriž near Cerkno belongs geographically geotectonically to Dinarides. consists two large inner thrust blocks Trnovo nappe, which were thrusted for tens kilometers direction SW their present position. They are overlain by Tolmin lowest unit Southern Alps. nappe was from N S a smaller intermediate sheet. In western part contact...

Les agriculteurs utilisant les eaux des khettaras, galeries souterraines drainant la nappe phréatique et donnant un accès collectif à l’eau souterraine dans oasis, font aujourd’hui face dilemme. khettaras se tarissent sous l’effet conjugué du pompage pour potable de l’irrigation exploitations agricoles nouvelles extensions, d’une recharge décroissante nappe. Leurs menacées disparition, certains...
