The Eocene rocks in Shabraweet area comprise the Lower, Middle and Upper Eocene stages. Each stage consists of only one rock unit; the Minia Formation, the Mokattam Formation and the Maadi Formation, respectively. The Minia Formation shows angular unconformity relationship with the underlying Cretaceous rocks and disconformity relationship with the overlying Mokattam Formation. The Maadi Format...

The Cotinguiba Formation, of Cretaceous age, located in the Sergipe-Alagoas Basin, Brazilian Northeastern coast, comprises carbonate breccias and shales interlayered with fine to coarse clastic sediments (mudstones, marls), deposited maximum sea level episode during Cenomanian-Coniacian transgressive event. Core sections were selected from formation materials, which 20 plugs obtained, represent...

The Raduha section represents a continuation of the research Anisian Strelovec Formation in Kamnik-Savinja Alps. was deposited during on drowned Serla Dolomite carbonate platform restricted probably outer ramp environment associated with an intraplatform basin. base is represented by dolostone breccia containing angular lithoclasts shallow-marine origin. This followed alternations laminated and...

An experimental programme was undertaken to develop a servo-controlled loading and high-fidelity data acquisition system to ~westigate acoustic emission (AE) waveforms produced during discrete fracture propagation in rock. Large (0.3 × 0.3 × I m) chevron-notched specimens were loaded in controlled conditions, and characteristic acoustic emissions associated with Mode I and Mode l l fracture wer...

Sparry magnesite deposits (SMD) of the Lower Riphean (LR) and Middle Riphean (MR) sequences in the western slope of the South Urals have some distinguished peculiarities, which allows to compare them and speculate about the mechanism of ore formation and Mg-source origin. LR magnesites are located in some stratigraphic levels and lie within widespread dolostone horizons. MR magnesites that occu...

Carbonate-associated sulfate (CAS) is an important proxy for reconstructing marine sulfur cycling throughout Earth's history. In order to assess the impact of carbonate neomorphism on δ34SCAS data, a mineralogical-spatial transect from early diagenetic limestone into low-temperature hydrothermal dolostone was analyzed in middle Triassic Latemar platform interior, northern Italy. This study addr...
