Thesis (MSc)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: This study presents results of a detailed geological mapping and structural analysis of auriferous quartz-vein sets of the nine current open-pit operations, of the Siguiri Mining Complex in the northeastern parts of Guinea. The Siguiri Mining Complex is hosted by a low-grade metamorphic, turbiditic succession within the larger Siguiri Basin, which forms part of the Palaeoproterozoic Birimian Supergroup of the Boualé-Mossi domain on the West African Craton. The Siguiri Mining Complex is located in a deeply weathered saprolite pr

New Guinea forms the northern margin of the Australian Plate which is now characterised by a zone crustal deformation and accreted terranes. The present day configuration is the result of global tectonics in the southwestern Pacific since the Triassic. The Papuan Fold Belt is located within Papua New Guinea, the eastern half of New Guinea, and comprises deformed basement, platformal and basinal Mesozoic and Tertiary sediments. Deformation within the fold belt commenced possibly as early as Middle to Late Miocene and is currently continuing. The structure of the western part of the Papuan Fold

Simberi Island is an eroded Pliocene alkaline volcano, the oldest in the Pliocene to Holocene Tabar-Lihir-Tanga-Feni (TLTF) island arc. These islands are derived from partial melting of subduction-modified mantle at $>$60 km depth along extensional, pull-apart structures. Explosive volcanism has brought samples of the mantle wedge to the surface. Within these samples are sulphate-, carbonate-, hydrous-, alkali-rich aluminosilicate glasses which represent quenched slab-derived magmas (SCHARM). SCHARM reacts with mantle peridotite to create a vertically zoned mantle wedge consisting of phlogopit

4D seismic analysis is used to understand the performance of a producing oil field in order to increase production and mitigate risk. This is done by interpreting changes in water saturation and changes in effective pressure in the reservoir, which allows production to be maximized safely. In this project, I determined saturation and pressure changes in an oil field offshore Equatorial Guinea. I used Landrø's technique as a basis for the analysis, however Landrø's technique requires the presence of reservoir samples.

Low velocity hydrous minerals in the subducting plate deliver water to the mantle and are thought to cause intermediate depth Wadati-Benioff zone (WBZ) seismicity through dehydration embrittlement. High frequency seismic energy (> 2 Hz) from intermediate depth earthquakes that occur within this low velocity oceanic crust is retained and delayed by the crustal waveguide while lower frequency (< 0.5 Hz) energy travels at the faster velocities of the surrounding mantle. These guided waves therefore spend longer interacting with the low velocity oceanic crust than any other seismic phase, and have

The development of an accurate and precise geochronology is imperative to understanding archives containing information about Earth’s past. Unable to date all intervals of an archive, researchers use methods of interpolation to approximate age between dates.

This stock was mapped as the Ok Tedi Intrusive Complex and divided into four separate bodies: the Mount Fubilan, Sydney Intrusion, Kalgoorlie, and Ningi Intrusions. Hydrothermal fluids caused alteration of the Mount Fubilan, and parts of the other intrusions, to potassic and propylitic mineral assemblages and deposited gold and copper. This investigation documents similarities and differences between the least-altered intrusive rocks of the complex and those that have undergo

The Porgera gold mine is a large, high-grade, vein and fault-hosted deposit located in the highlands of Papua New Guinea. Gold mineralisation at Porgera is spatially associated with oxidised, hydrous magmas of the Porgera Intrusive Complex. Prior to emplacement of the intrusive complex, the Porgera area experienced a period of shortening due to collision of a southward-moving arc with the northern edge of Papua New Guinea. Two stages of mineralisation which have distinct mineral assemblages and structural association, formed shortly after emplacement of the intrusive complex at a depth o

The Lihir gold deposit is the world’s largest alkalic low-sulfidation epithermal gold deposit in terms of contained gold (50 Moz). The deposit formed over the past ~500 kyr and records a progression from porphyry to epithermal-style hydrothermal activity. Lihir is located on the eastern shore of Lihir Island, in the TLTF island arc of New Ireland Province, Papua New Guinea. Its formation has been coincident with alkalic magmatism along arc-oblique extensional structures and sinistral rotation in the back-arc of the New Britain subduction zone. The deposit is centered on Luise Volcano, a well-p

Annotation:
The Golpu porphyry and Wafi epithermal deposit of Papua New Guinea contains contrasting styles of epithermal veins and alteration that overprinted early-formed porphyry-style mineralisation. Golpu is the easternmost and oldest porphyry deposit in a previously unrecognised belt that includes most of the porphyry deposits in the New Guinea Orogen. This metallogenic belt was formed in an orogenic regime that was driven by west-directed, low-angle subduction of an antiformal slab of oceanic lithosphere (the Solomon Sea Plate). The regional stratigraphy at Golpu comprises Mesozoic metasediment

New Guinea has long been recognized by geologists as the location of geologically recent mountain building. This study combined field mapping, stratigraphic and remote sensing analysis along and near the Gunung Bijih (Ertsberg) mine road and mining district in order to analyze the geologic development of the collisional New Guinea orogen. As a result of the youthfulness and the quality of data, it is possible to constrain distinct parts of orogenic evolution to 1 or 2 m.y. The southern Central Range of New Guinea is located on the northern Australian continental margin. The southern one-third

The Great Barrier Reef (GBR) margin, located on the continental margin between Papua New Guinea and northeast Australia, is the largest extant example of a tropical mixed siliciclastic-carbonate depositional system. It is constructed by the combined input of terrigenous siliciclastic sediment delivered through riverine transport and biogenous carbonate sediment from neritic and pelagic production. This study investigates late Quaternary changes in sediment dispersal and accumulation on the slopes of this margin. Sedimentation across the GBR mixed system also serves as an important analog for u

The Lihir gold deposit (also known as Ladolam), has a 56 Moz resource and is the world’s largest alkalic gold deposit in terms of contained gold. It is located on Lihir Island, part of the Tabar-Lihir-Tanga-Feni island chain, New Ireland Province, Papua New Guinea. The Tabar-Lihir-Tanga-Feni island chain formed in a complex tectonic environment over the past four million years. Docking of the colossal Ontong Java Plateau at the Melanesian trench during the Miocene caused near-complete cessation of magmatism and a reversal of subduction polarity, forming the markedly northward-convex New Brita

The 56 Moz Ladolam gold deposit, with an average gold grade of 2.42 g/t, has previously been recognised as the world’s largest known epithermal gold deposit. It is located on Lihir Island, in the New Ireland Province of Papua New Guinea, and is part of the Tabar- Lihir-Tanga-Feni chain of Pleistocene alkalic volcanoes. Alkalic magmatism occurred in an extensional tectonic regime, in a location where initial arc magmatism was related to subduction with the Manus-Kilimailau trench, but was later reactivated as a back arc due to the subduction of the Solomon Sea plate along the New Britain
