EFFECTS OF MICROTEXTURAL INTERACTIONS OF ORGANICS AND SILICA ON SILICA DIAGENESIS
… impurities on a macroscale and ignore potential microtextural interactions of silica and organic material. In this thesis, I present a set of experiments designed to characterize the effect of organic matter distribution on the opal-A to opal-CT transition in siliceous sedimentary rocks. Silica, …

Evaluating the Sensitivity of the Auckland Pavement Polishing Device and Analysis of Aggregate Microtextural Wear
… using the APPD device or the evolution of microtextural wear during the polishing process. Consequently, this research: Evaluates the sensitivity of the APPD polishing mechanism to changes in the aforementioned setup conditions, as measured by corresponding changes in the coefficient of …

Petrology and geochemistry of pyroxenites in the Lanzo ultramafic massif, Northwestern Italy
Combined field, microtextural, and geochemical observations are presented for pyroxenites in the Lanzo ultramafic massif in order to place chemical and petrological constraints both locally on the geologic history of the massif and more generally on the role of magmatic rifting and the …

Experimental Evaluation and Simulations of Fiber Orientation in Injection Molding of Polymers Containing Short Glass Fibers
… at the shell, transition and core layer, and microtextural description of the advancing front are included in this dissertation. The analysis and assessment of the radial evolution of fiber orientation and advancing front based on comparing the experimental data with simulation results are …

Shape and Texture in Quartz Sand Grains: A Quantitative Assessment
Thirty years of microtextural study of quartz grain form has revealed many different textural types and shapes. In conjunction with other sedimentological methods, surface textures and shapes have been assigned to quartz grains from a variety of depositional settings. Many different methods have …

Integrating rotational components to optical properties observed in petrographic thin sections via automated image acquisition and analysis
… of the minerals present as well as providing microtextural data for the minerals observed. Textural data for mineral groups are extracted such as grain shape, size and orientation. To achieve this, workflows were established for the acquisition and compositing of data to optimise the image …
