Abstract:

The golden generation have a wealth of experience and knowledge from throughout their lifetimes that younger generations wish to retain. In our technology filled world an obvious means of collecting this information is electronically. Digital library col- lections are increasingly used by libraries and large institutions to record their large amounts of information but they can also be used for personal collections. Seniors are often willing and keen to impart their years of experience upon people of the younger generation but time is not always on their side as they grow older. Throughout a l

Abstract:

This thesis examines the origin and relative timing of carbonate alteration zones in the poly-deformed Doolena Gap Greenstone Belt in the East Pilbara Terrane, the type locality of Archaean dome-and-keel-terranes. The key findings are: [1] shear-assisted carbonate alteration occurred throughout the entire tectonic history of the greenstone belt; and [2] weak pre- and syntectonic carbonate minerals make up 40 to 60% of the examined greenstone rocks. These outcomes imply that carbonate minerals likely controlled the strength of Archaean lithosphere.

Abstract:

The Belingwe greenstone belt in southern Zimbabwe contains one of the most well preserved Archean volcanic successions in the world. The komatiites in this succession have been studied in great detail, but the associated basalts have received much less attention. A detailed study of these basalts in the Zeederbergs Formation has revealed the existence of a previously unrecognised lava type which has important implications for the petrogenesis of the suite. The Zeederbergs Formation and the underlying Reliance Formation form the 2.7 Ga Ngezi Group volcanics, which are underlain by thin, general

This is of particular research interest because the Paleoarchaean rock record is considered to lack K2O-rich magmatic rocks. Previous studies on the felsic igneous rocks of the H6 unit have proposed that these rhyolites are K-metasomatised eruptive equivalents of the sodium-rich ~3.45 Ga TTGs of the BGGT and that the

A low-density reconnaissance geochemical survey was made of the stream sediments and rocks in the Akaka/Ago-Iwoye, Egbe and Igbo-Ora districts of the southwestern basement complex, Nigeria.

Typical rain forest areas and streams are dissected by a closely and deeply developed dentritic-subdentritic drainage pattern.

Abstract:

The potentially hazardous nature of open pit mining requires the application of sound geotechnical engineering practice to mine design, for the purpose of permitting safe and economic mining of any commodity within any rock mass. The Lerala Diamond Project is situated in the south west of Botswana near the Martin’s Drift Border Post. A 2m-soil cover made surface mapping of geological features impossible, so a number of geotechnical holes were drilled to evaluate the characteristics of the kimberlite pipes and the Granite/gneiss host rock.

This study investigates issues of changing recreation use and management in the Greenstone and Caples Valleys. Its underlying research themes are the differing characteristics and activities of four distinct user-groups, how such differences could contribute to conflict in recreation use and management, and the implications of such for management. The conceptual framework used to deal with these issues is the Recreation Opportunity Spectrum (ROS), which is based upon the assumption that quality in recreation experiences and management is best achieved through provision of a range of recreation

The Nyanzian lavas represent a diverse range from basalts and basaltic andesites, through andesites and dacites to rhyolites. From geochemical studies the basalts and basaltic andesites are tholeiitic, whereas the andesites, dacites and rhyolites are calc-alkalin

Variolites are mafic to intermediate volcanic rocks containing centimetre-sized, spherical domains, termed varioles. Varioles are dominantly composed of plagioclase spherulites.

Abstract:

O presente trabalho procurou identificar e definir os principais eventos geológicos sobre a evolução crustal dos terrenos granito-greenstone de Manica, região centro-oeste de Moçambique. O distrito de Manica localiza-se no centro-oeste de Moçambique entre as latitudes 18°50\'S - 19°00\'S e as longitudes 32°45\'E - 32°55\'E. É predominantemente constituída por terrenos da assembléia granito-greenstone belts de idade Arqueana e representa o prolongamento para leste do Cráton do Zimbabwe. O Greenstone belt de Manica é composto por uma sequência de metavulcanitos máficos e ultramáficos (Formação d

Abstract:

The ca. 2720 Ma Vermilion, Shebandowan, Winston Lake, and Manitouwadge greenstone belts (VGB, SGB, WGB, and MGB, respectively) are located along the northern margin of the Wawa subprovince. They are interpreted to have formed in broadly similar rifted arc to back-arc environments, but their base and precious endowment and, in particular, their endowment in VMS deposits, differ markedly. These difference is metal endowment reflect differences in their metallogenic history that were examined by comparing their regional, belt-scale lithostratigraphy, chemostratigraphy, petrogenesis and tectonic h

Abstract:

The Timiskaming Group is a late Archaean syn-tectonic lithological unit which lies unconformably on greenstone-belt volcanic rocks and consists of an alluvial-fluvial assemblage intercalated with alkalic volcanic rocks and a turbidite assemblage. The fine-grained sedimentary rocks of the alluvial-fluvial assemblage and turbidite north unit have similar mineralogical and chemical compositions such as high SiO$\sb2$, U, Th and total rare-earth elements (REE). The turbidite south unit has high Fe$\sb2$O$\sb{3(\rm tot)}$, MgO, TiO$\sb2$, Cr and Ni. Petrographic and geochemical examinations of clas

Abstract:

Part of the Slave Structural Province, the Hope Bay Greenstone Belt is a 82 km long north-striking sequence of supracrustal rocks dominated by mafic volcanic rocks with lesser felsic volcanic and sedimentary rocks. Mapping of two transects in the southern section and two transects in the northern section have contributed to a robust stratigraphic framework the belt. Three recently discovered Archean lode gold deposits in the Hope Bay Greenstone belt have associations with major structures and specific lithologies (Fe-Ti enriched basalts). The Flake Lake and the Clover Transects are in the

Abstract:

The Nuvvuagittuq greenstone belt is an Eoarchean/Hadean succession preserved along the eastern coast of Hudson Bay in the Northeastern Superior Province, Quebec, Canada. It is essentially composed of three major lithological units: 1) mafic cummingtonite-amphibolite, known as the "faux-amphibolite", which is the dominant lithology of the belt, 2) ultramafic and mafic sills that intrude the faux-amphibolite, and 3) chemical sedimentary rocks comprising a banded iron formation (BIF) and a silica-formation. The faux-amphibolite has a basaltic to andesitic composition. It is comp
