To investigate pedological criterion on land degradation in Quaternary rock units, at first, a part of the shoor watershed area was selected. After distinguishing target area, slope classes, land use and geology maps were created, then map of units were founded by overlaying and crossing these maps. In this research three indices of erodibility, salinity and permeability of soils were considere...

We describe a vision for national-scale heavy mineral (HM) map generated through automated mineralogical identification and quantification of HMs contained in floodplain sediments from large catchments covering most Australia. The composition the reflects dominant rock types each catchment, with generally resistant largely preserving fingerprint their host protoliths weathering-transport-deposi...

investigation of desertification trend needs understanding of phenomena creating changes singly or action and reaction together in the manner that these changes were ended up in land degradation. in investigation of pedological criterion onland degradation in quaternary rock units, first, a part of the rude-shoor watershed area was selected. after distinguishing target area, maps of slope class...

Mineral physicist Steven Jacobsen uses high pressure-temperature experimental techniques to investigate the properties of mantle mineral phases such as ringwoodite, the blue crystal (left) pictured through the top of a diamond-anvil cell. Jacobsen’s studies will help EPS seismologist Suzan van der Lee map the Earth’s interior as they attempt to identify the driving forces behind plate tectonics...

Tahltan Lake (104G113) map areas. This work adjoins and locally updates mapping in the Yehiniko Lake and Scud River areas (Brown and Gunning, IY8Y)a. b: Brown and Greig; IYYO. Browl: c t r r l . , 1990). The project objectives are to provide new 1:SO OOO-scale geologic maps accompanied by up-to-date geochemical and mineral occurrence data. and an assessment of thc mineral potential of the area....

in this study, the reliability of the primary gold mineralization exploration using multispectral etm+ imagery was investigated in lahroud region, northwest iran, which was conducted by integration of alteration and structural indicators. co-occurrence of the clay minerals and iron oxides is an important criterion in gold deposit exploration; therefore, their alteration zones were mapped using ...

We present a framework for characterizing spike (and spiketrain) synchrony in parallel neuronal spike trains that is based on identifying spikes with what we call influence maps: real-valued functions describing an influence region around the corresponding spike times within which possibly graded synchrony with other spikes is defined. We formalize two models of synchrony in this framework: the...

Ecotourism as the most attractive subset of the tourism industry can contribute to natural resource conservation and local development. Although great numbers of people annually visit Abbasabad area, in Veresk, Mazandaran, to enjoy its brilliant landscape and moderate ecologic condition, there is no applicable plan for many natural attractive zones in this area. As a result, some specific well ...
