Characterization of Rock Populations on Planetary Surfaces
Characteristics of rock populations on the surfaces of Mars and Venus can be derived from analyses of rock morphology and morphometry data. We present measurements of rock sizes and sphericifies made from Viking lander images using an interactive digital image display system. The rocks considered are in the gravel size range (16-256 mm in diameter). Mean sphericities, form ratios, and roundness...
متن کاملQuantitative Estimates of Bio-Remodeling on Coastal Rock Surfaces
Remodeling of rocky coasts and erosion rates have been widely studied in past years, but not all the involved processes acting over rocks surface have been quantitatively evaluated yet. The first goal of this paper is to revise the different methodologies employed in the quantification of the effect of biotic agents on rocks exposed to coastal morphologic agents, comparing their efficiency. Sec...
متن کاملModeling Roughness of Rock Discontinuity Surfaces: A Signal Analysis Approach
Barton’s (1973) model for estimating the peak shear strength of rock discontinuity surfaces includes an input variable, called joint roughness coefficient (JRC). Using this model, Barton and Choubey (1977) empirically determined the JRC values of a large number of discontinuities and designated a set of ten roughness profiles (Fig. 1) that represents the JRC range of 0–20. These ten profiles co...

Sorption phenomena are known to play significant roles in metal mobility in mine drainage waters. The present study focuses on sorption phenomena controlling Ni concentrations in contaminated neutral drainage issue...
متن کاملClassification of Mars Pathfinder Rock Surfaces Using Quantitative Morphologic Indices
Background: The Mars Pathfinder (MPF) landing site was originally predicted to contain a broad sampling of rock types varying in mineralogical, physical, mechanical and geochemical characteristics. Although rocks have been divided into several spectral categories based on Imager for Mars Pathfinder (IMP) visi-ble/near-infrared spectra, it has not been fully determined which of these categories ...
