This study tests the feasibility of using Polynomial Texture Map (PTM) recording technology at Roughting Linn rock art site. Additionally, it examines the added value of incorporating PTM into the existing record of the rock carvings. Finally, it explores the application of PTM as a tool to enhance the understanding of cultural significance of the ancient site. A Polynomial Texture Map (PTM) is...
There is a huge chasm between the sort of lawful determination that figures in fundamental physics, and the sort of causal determination that figures in the ‘folk physics’ of everyday objects. For example, consider a rock sitting on a desk. In everyday life, we think of the rock as having a fixed stock of dispositions--the disposition to slide on the desk when pushed, to shatter when struck by ...
Seismic techniques for direct hydrocarbon indication rely on the changes in seismic character which accompany changes in pore fluid content. Interpretation and modeling of direct hydrocarbon indicators (DHIs) require an understanding of the factors affecting seismic velocities and reflection coefficients which are, in turn, dependent on pore fluid properties, rock frame properties, and fluid su...
Many properties of complex porous media such as reservoir rocks are strongly affected by heterogeneity at different scales. Complex depositional and diagenetic processes have a strong control on the pore structures, leading to systems with wide range sizes covering many orders magnitude in length This poses significant challenge for digital rock analysis since single resolution image associated...
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...
The determination of mineral quantities is one of the primary purposes of petrology and economic geology studies. When producing skarn zonation, it is necessary for the quantities of minerals in each zone to be known. Currently, various methods of determination for mineral quantities in rock bodies have been developed, but a rapid, accurate and economic method for distinguishing 3D mineral dist...
