The mineralogical deportment of radionuclides in South Australian Ca-Au-(U) ores
… necessitates a detailed understanding of their mineralogical deportment as a pre-requisite for attempts to remove or reduce RN concentrations. Research presented in this thesis contributes towards this knowledge by identifying and characterising potential RN-carriers, migration of radiogenic …

Formation of mineralogical zonations in ophiolites through reactive porous flow : a modeling study
In the mantle section of many ophiolite sequences, dunite dikes are present. Around dunite dikes at the Josephine and Trinity ophiolite, a sequence of lithologies consisting of plagioclase lherzolite, lherzolite, and harzburgite is present. This sequence of rocks has been interpreted to be the …

A genetic and mineralogical study of two soils from the Davis Mountain Region, Texas
The primary purpose of this study was to acquire information concerning the genesis of two soils developed from volcanic materials. Secondary objectives were to establish modal profiles for use in classification of the soils.

Geochemical and mineralogical impacts of sulfuric acid on clays between pH 5.0 and -3.0
… cell studies, investigating the geochemical and mineralogical impacts of H2SO4 solutions (pH 5.0 to -3.0), were conducted on three mineralogically distinct clays (Kc, Km, and BK). Batch testing was conducted at seven pH treatments (5.0, 3.0, 1.0, 0.0, -1.0, -2.0 and -3.0) using standardized …

Bedrock target analysis for ROV rockdrill sampling and existing sample stratigraphic and mineralogical verification (BeTar_drill)
The dynamic seascapes found in continental margin settings generally host many vertical structures, such as fault escarpments and submarine canyon systems. This terrain is exemplified on the Irish Atlantic Margin (IAM) by the Porcupine Bank Canyon (PBC). Bedrock has been found here in the past, …
