Rocks metamorphosed under high-pressure (HP) and ultra high-pressure (UHP) conditions in subduction zones come back to the surface relatively soon after their burial and at rates comparable to plate boundary velocities. In the Mediterranean realm, their occurrence in several belts related to a single subduction event shows that the burial-exhumation cycle is a recurrent transient process. Using...

for many years many scholars made comments about zaynab’s burial place and each tried to approve or disapprove one of the places, until with the evidences that all of them are at hand for analysis, research and criticism, concluded to a definite result, but this is still in ambiguity and uncertainty. it is in author’s mind for many years that because of different views and disagreements, where ...

Large bedforms in the nearshore (with heights of 10 – 50 cm and lengths of 1-10 m) are observed to occur frequently and to be ubiquitous throughout the surf zone (e.g., Clifton et al. 1971, Gallagher et al. 2002, Hay and Wilson 1994, Thornton et al. 1998). However, their dynamics are poorly understood and they are generally neglected in models of sediment transport, morphology change and nearsh...

a study of the diagenetic evolution of sandstones from panyu low-uplift in the pearl river mouth basin was carried out to unravel the controls on shelf margin sandstone reservoir quality. the reservoir rocks, oligocene volcanic clastic sandstones of the zhuhai formation, have a burial depth of 2765 to 3440 m. 70 samples were studied using the granulometric analyses, x-ray diffraction (xrd) anal...
