The mineralogy and related geology of the Albert Silver Mine, Bronkhorstspruit, Transvaal
(1970)The Albert Silver mine is situated on the farm Roodepoortjie, 32 kilometres north of Brorikhorstspruit in the Transvaal. The deposit forms the largest of a number of sub-parallel quartzhematite lodes accompanied by sulphide ... -
The late cenozoic carnivora of the south-western Cape Province.
(1972)Abstract available in PDF file. -
The hydrogeology of Botswana.
(1974)Botswana covers an area of 570 000 km and has a population of about 600 000. It is estimated that three-quarters of the human and livestock populations are dependent on ground water, with an estimated 26 x 10 m of water ... -
Aspects of Karroo vulcanicity in the Komatipoort area Lebombo.
(1979)The petrology, mineralogy and geochemistry of the Karroo-age basaltic and rhyodacitic volcanics present in the Lebombo Belt near Komatipoort, Eastern Transvaal, Republic of South Africa are described. The volcanics ... -
Stratigraphy and sedimentology of the Molteno formation in the Elliot and Indwe area, Cape Province.
(1981)Abstract in PDF file. -
The lithostratigraphy and petrogenesis of the Nsuze group northwest of Nkandla, Natal.
(1984)The volcanic and sedimentary Nsuze Group constitutes the lower part of the -
The petrology and geochemistry of intrusions at selected nunataks in the Ahlmannryggen and Giaeverryggen, western Dronning Maud Land, Antarctica.
(1986)The mid-Proterozoic Borgmassivet intrusions of western Dronning Maud Land intrude Archaean granites and a volcano-sedimentary sequence, the Ritscherflya Supergroup. They are SiO2-rich ultramafic to mafic tholeiitic rocks ... -
Sedimentary models for coal formation in the Klip River coalfield.
(1988)The primary objective of this study was to establish sedimentary models for peat formation in the southern part of the Klip River coalfield during Ecca (Permian) times and to assess palaeoenvironmental controls on coal ... -
The petrology, geochemistry and classification of the Bien Venue massive sulphide deposit, Barberton mountain land.
(1990)The Bien Venue massive sulphide deposit is associated with a felsic volcanic succession developed in the north-eastern part of the Barberton Greenstone Belt, Eastern Transvaal. The deposit is situated 8km east-north-east ... -
Sedimentology, coral reef zonation, and late Pleistocene coastline models of the Sodwana Bay continental shelf, Northern Zululand
(1991)This geostrophic current-controlled Zululand/Natal shelf displays a unique assemblage of interesting physical, sedimentological and biological phenomena. The shelf in this area is extremely narrow compared to the global ... -
Alkaline intrusives from the Tugela terrane, Natal metamorphic province.
(1991)Three gneissose alkaline granitoid intrusives at Ngoye, Bulls Run and Wangu are described. They are located within the Nkomo Nappe of the Tugela Terrane, near the northern margin of the Natal Metamorphic Province. The ... -
Sedimentary models and geomorphological classification of river-mouths on a subtropical, wave-dominated coast, Natal, South Africa.
(1991)Abstract available in PDF. -
Zinc-lead mineralization at Pering Mine in the Griqualand West sub-basin : an isotopic study.
(1992)Detailed studies, both chemical and physical, have been performed on various dolomites and vug-filling carbonates, to determine the pathways and extent of the mineralizing fluids associated with the Pering Zn-Pb deposit ... -
Richards Bay zircon.
(1992)Zircon from the zircon concentrate of Richards Bay Minerals was investigated with a view to understanding the morphology and provenance. The obsevations were applied to the reduction of uranium, thorium and other trace ... -
Geological evolution of western H.U. Sverdrupfjella, Dronning Maud land, Antarctica.
(1992)The oldest rocks of western H.U. Sverdrupfjella, the Jutulrora Formation, consist of interlayered mafic to felsic ortho- and paragneisses thought to represent calc-alkaline volcanic and clastic sedimentary rocks. These ... -
The petrology and geochemistry of the karoo sequence basaltic rocks in the Natal Drakensberg at Sani Pass.
(1992)The Sani Pass in the Natal Drakensberg is situated in the north-eastern sector of the Lesotho Highlands which forms a major Karoo-age basaltic massif in the Karoo Igneous Province. The volcanic section exposed in the ... -
A two-dimensional hydrodynamic model for the St Lucia Estuary mouth.
(1993)The reduced fresh water input into the St Lucia Estuary combined with the increase of sediment in the St Lucia Lake System has necessitated the implementation of a dredging programme. To ensure the effectiveness of the ... -
The geology and geochemistry of the volcanic rocks of the Pongola sequence in southern Swaziland.
(1993)The ~3.0 Ga Pongola Sequence, comprising a lower dominantly volcanic Nsuze Group and an upper largely sedimentary Mozaan Group, crops out in the Mahlangatsha and Kubuta areas of southern Swaziland. The Nsuze Group consists ... -
A study of titanium-bearing oxides in heavy mineral deposits along the East Coast of South Africa.
(1993)Heavy mineral deposits along the east coast of South Africa represent the world's largest demonstrated resource of beach placer ilmenite. This mineral occurs as homogeneous, subrounded grains, with chemical compositions ...
