micromorphology is the branch of soil science that is concerned with the description, interpretation and, to an increasing extent, the measurement of components, features and fabrics in soils at microscopic level. the advantage of micromorphology is that, in micromorphological studies the soils are studied in their natural and undisturbed form and so, one can follow the processes that take plac...

Introduction. The current hypothesis is that Martian sinkholes do not exist. It is proposed that the low pH environment resulting from the high CO2 content of the atmosphere will cause calcium carbonate to be deposited as calcite cemented sandstone rather than limestone [5]. Calcite, as well as gypsum, halite, smectite and illite, has been detected in Martian meteorites providing proof of the p...

Titanium oxynitrides (Ti(N,O,C)) are abundant in xenolithic corundum aggregates pyroclastic ejecta of Cretaceous volcanoes on Mount Carmel, northern Israel. Petrographic observations indicate that most these nitrides existed as melts, immiscible with coexisting silicate and Fe-Ti-C silicide melts; some may also have crystallized directly from the melts. The TiN phase shows a wide range solid so...

This research focuses on the analysis of influence two secondary salt weathering processes durability rocks exposed to marine environments: chemical dissolution rock forming minerals and differential thermal expansion between halite hosting rock. These are scarcely treated in compared crystallisation. The methodology followed this paper includes both situ monitoring laboratory simulations. Four...
