One of the characters in Iranian Model of Desertification Potential Assessment (IMDPA) is soil. Since soil is very important in the degradation of land, so some indices were determined for this character in order to evaluate desertification potential of arid, semi-arid and dry sub humid areas of Iran. The indices included soil texture, deep gravel percentage, soil depth, and EC. To calibrate th...

Glen Torridon (GT) is a recessive-trough feature on the northwestern slope of “Mt. Sharp” in Gale crater, Mars with highest Fe-/Mg-phyllosilicates abundances detected by Curiosity rover to date. Understanding origin these clay minerals and their relationship diagenetic processes critical for reconstructing nature habitability past surface subsurface environments crater. We aim constrain distrib...

The Glen Torridon stratigraphic sequence marks the transition from low energy lacustrine-dominated Murray formation (Mf) (Jura member: Jm) to more diverse Carolyn Shoemaker (CSf) (Knockfarril Hill Knockfarril Hill; Glasgow Glasgow). This defines a change in depositional setting. Alpha Particle X-ray Spectrometer (APXS) results and statistical analysis reveal that bulk primary geochemistry of Mf...

We explore the coastal morphology along an uplifting 500 km-long segment of Central Andes, between cities Chala (Peru) and Arica (Chile). use accurate DEM field surveys to extract sequences uplifted shorelines study area. In addition, we consider continental pediment surfaces that limit both geographical vertical extent marine landforms. establish a chronology based on published dates for landf...

Aeromagnetic data and Landsat image, were assessed to establish a relationship between morphostructural feature borehole yield of sub-basin Osun basin in the Northern part Ilesha, southwestern Nigeria. Four factors (Geomorphological unit, Slope, regional structure, lineament) considered. Geomorphological units classified based on digital elevation model (DEM), Lineaments identified extracted us...

The dynamic inter-relationships between marine and freshwater carbonate depositional environments are illustrated in the Sian Ka'an Wetlands, a 5 280 km2 complex of groundwater-fed marshes, lakes brackish coastal lagoons South-East Yucatán Peninsula (Mexico). Platform was subaerially emergent extensively karstified during last glacial maximum at 18, 000 yr bp. Late Holocene transgression has ca...

The proposed area for establishment of Phu Yen Geopark is limited to 6 districts, towns and cities, including: Tuy Hoa City, Dong provincial town, An district, Song Cau town 3 communes, 1 in district communes Son with an 1,575 km2. Distributed the central coastal line, area's topography quite diverse, including mountains, hills, plains areas, divided into main origin types: 1) Terrain tectonics...
