The Upper Cretaceous sedimentary succession cropping out in the Sainte-Baume Massif (Var, southeastern France) is of late Turonian to Campanian age. There, complex imbrication and rapid evolution space time shallow-marine, fluvio-deltaic lacustrine environments at front North Provence Durancian uplift occur during Santonian. Marly and/or sandy strata rich lignite remains amber grains are inters...

Soft rocks in various forms of marly materials have an important role the geological structure Dalmatia (Croatia) and Budapest region (Hungary). These can cause serious problems design construction, due to their complex behavior under atmospheric conditions. For purpose better understanding soft properties, a database with approximately 600 samples collected throughout was made collated along 2...

today's, adverse effects of off-site erosion, namely damages received from sediment, is a serious bioenvironmental problem. one of the methods for temporary soil stabilization before permanent rehabilitation of vegetation cover, especially on slopes, for mitigating of bioenvironmental contaminants, is using materials having property to cementate the dispersed particles on the soil surface....

At least potentially karstifiable rocks cover much of the surface of Egypt and northern Libya. Study of caves and other karstic features of this region has been hampered by lack of roads, rapid disintegration of the surface of friable, poorly consolidated limestone, wind-blown sand and other factors. Interbedding with marly aquicludes hampers speleogenesis locally. Calcareous and evaporite kars...
