Abstract:

Magmatic stoping is a term that has been controversial almost since it was first mentioned over a century ago. Scientists have been arguing whether it plays an important part as an emplacement process of magma chambers, or whether it takes place at all. With growing evidence for both pro- and counterar guments the debate becomes tenser and the question raised is whether it is possible to find a unanimous answer. Magmatic stoping is often associated with the presence of xenoliths, “foreign” rocks that have been enclosed by magma. As parts of the roof or walls in the magma chamber detach, the pi

Abstract:

Includes bibliographical references (leaves 153-157). Petrographic image analysis proved particularly useful in determining the parameters for statistical analysis for the simple mineralogies displayed in the samples from the Hutton Sandstone. Concentrates on establishing techniques for statistical study of data collected by PIA to subdivide the framework grains from the porosity or cement.

Abstract:

En el Sáhara Occidental hay dos unidades principales: la cobertera sedimentaria del Fanerozoico y un basamento cristalino que forma parte del cratón del África Occidental, constituido desde el Paleoarcaico al Paleoproterozoico. A su vez, en el basamento se ha definido una serie de dominios o terranes, delimitados por fallas regionales, que responden a microcontinentes que colisionaron principalmente durante la orogenia Birimiense y la Hercínica. Los primeros estadios de granitización parecen producirse entre el Paleoproterozoico y el Mesoproterozoico dependiendo del dominio, pero el primer g

Abstract:

Indium is extensively used in LCD screens and solar cells. It is mainly produced as a byproduct during ore processing. With ever increasing demand for indium and most of the production being restricted to a few countries new sources for indium are needed. In Sweden, the westernmost Bergslagen is the only area, which is known to exhibit minerals with essential indium. The indium mineralisations at Långban, the Linbom prospect, which are studied in this bachelor’s thesis show several trends. The most notable is the copper indium trend seen in sphalerite. A likely substitution based on similar io

Abstract:

In nature there are about 4,500 minerals identified. These can roughly be divided into two groups, opaque phases and non-opaque phases, with the exception that some opaque phases also may act as a non-opaque phase in different circumstances. The division is made on the basis of the optical properties. Opaque phases are nontransparent, which means that a different type of microscope must be used. A conventional microscope uses transmitted light while the microscope for opaque phases or the ore microscope uses reflected light. The reason is that ore minerals often behave in an opaque manner.

Abstract:

Quartz-carbonate vein Au deposits in the Timmins-Porcupine gold camp, Abitibi Subprovince, have equivocal protracted parageneses and formed during late to post-Kenoran (2750-2670 Ma) deformation and metamorphism. SIMS U-Pb and delta18O depth-profiling and LA-ICPMS REE depth-profiling techniques were employed on unpolished wallrock zircons to resolve temporal constraints on mineralization and hydrothermal fluid sources at Hoyle Pond and Pamour mines. Depth-profiling techniques successfully uncovered <3 mum alteration domains in zircon rims based on Th/U, REE, and isotopic signatures, and rim

Abstract:

Analysis of the facies and sequence stratigraphy of tidally-influenced, siliciclastic-dominated successions from five different areas has allowed a survey and comparison of the sedimentological and architectural characteristics of a variety of tidal sandstone body types. This study is concerned with: (i) describing these different sandstone body types; (ii) analysing the controls on sandstone body internal architecture, external geometry and connectivity, and (iii) outlining the implications of such studies for reservoir characterisation. Facies analysis of the studied successions by previous
