  • The Structural Evolution of the Kombat Deposits, Otavi Mountainland, Namibia
    Communs geol. Surv. Namibia, 10 (1995), 99-107 The structural evolution of the Kombat deposits, Otavi Mountainland, Namibia J.G.Deane Gold Fields Namibia, P.O. Box 3718, Windhoek, Namibia The main phase of the Kombat Cu-Pb (Ag) mineralization is interpreted as being stratabound and syntectonic. The ore deposits are located in Hüttenberg Formation carbonates, on the Northern Platform margin of the Damara Province. Mineralization occurs on the contact with the overlying Kombat Formation phyllite. The deposits form a near-linear east-west trend of pendant-shaped ore loci with a strike length of 6 km. Characteristic features are the abundance of sandstone in Damaran-age karsts, Fe-Mn oxide/silicate as- semblages, intense faulting, fracturing, shearing and brecciation. A strong calcite alteration halo encompasses the deposits. The calcite alteration is of various ages, and therefore not always related to the mineralizing event. The association of stratiform Fe-Mn oxide/ silicate assemblages with the Kombat deposits has led to conflicting ideas regarding the genesis of these deposits. Field evidence, supported by analytical results, has led to the construction of a genetic model for the mineralization and Fe-Mn assemblages. A marine transgression, resulting from late-stage rift tectonism, drowned the southern parts of the Otavi Valley basin. This allowed for deep- seated hydrothermal fluids from the northern graben to migrate up the rift structures, enter the Otavi Valley basin, and deposit Fe and Mn as oxide/silicate assemblages in favourable third-order structures on the platform margin. It is probable that an early phase of Cu mineralization was related to these diagenetic processes.

  • The Cassinga Massacre of Namibian Exiles in 1978 and the Conflicts Between Survivors’ Memories and Testimonies
    ENDURING SUFFERING: THE CASSINGA MASSACRE OF NAMIBIAN EXILES IN 1978 AND THE CONFLICTS BETWEEN SURVIVORS’ MEMORIES AND TESTIMONIES BY VILHO AMUKWAYA SHIGWEDHA A Dissertation submitted for the degree of Doctor of Philosophy in History University of the Western Cape December 2011 Supervisor: Professor Patricia Hayes ABSTRACT During the peak of apartheid, the South African Defence Force (SADF) killed close to a thousand Namibian exiles at Cassinga in southern Angola. This happened on May 4 1978. In recent years, Namibia commemorates this day, nationwide, in remembrance of those killed and disappeared following the Cassinga attack. During each Cassinga anniversary, survivors are modelled into „living testimonies‟ of the Cassinga massacre. Customarily, at every occasion marking this event, a survivor is delegated to unpack, on behalf of other survivors, „memories of Cassinga‟ so that the inexperienced audience understands what happened on that day. Besides survivors‟ testimonies, edited video footage showing, among others, wrecks in the camp, wounded victims laying in hospital beds, an open mass grave with dead bodies, SADF paratroopers purportedly marching in Cassinga is also screened for the audience to witness the agony of that day. Interestingly, the way such presentations are constructed draw challenging questions. For example, how can the visual and oral presentations of the Cassinga violence epitomize actual memories of the Cassinga massacre? How is it possible that such presentations can generate a sense of remembrance against forgetfulness of those who did not experience that traumatic event? When I interviewed a number of survivors (2007 - 2010), they saw no analogy between testimony (visual or oral) and memory. They argued that memory unlike testimony is personal (solid, inexplicable and indescribable).

  • App-001723 Operations of Van Dyk Petroleum's Diesel
    APP-001723 OPERATIONS OF VAN DYK PETROLEUM’S DIESEL WHOLESALE FACILITY, GROOTFONTEIN ENVIRONMENTAL MANAGEMENT PLAN Assessed by: Assessed for: Aug 2020 EXECUTIVE SUMMARY Van Dyk Petroleum CC requested Geo Pollution Technologies (Pty) Ltd to prepare an environmental management plan (EMP) for their existing diesel wholesale facility on erf 242, Maroela Street, Grootfontein. The facility operates under a wholesale licence issued by the Ministry of Mines and Energy and supplies diesel to farmers and businesses in the area. For this purposes, one aboveground 23 m3 steel tank, with concrete bunding, is present on site. Two small tanker trucks of the Proponent collects diesel from the tank for transport to clients. The tank in turn is filled with a large tanker truck, from a bulk fuel storage facility, as needed. Van Dyk Petroleum is also contracted by other members of the petroleum industry to transport fuel from the bulk fuel storage facilities in Walvis Bay, to various storage and retail facilities in northern Namibia. For this purpose the Proponent has a fleet of tanker trucks consisting of 17 trucks and 16 fuel tankers. The Proponent services his truck fleet on the premises when required. Used mineral oil, drained from vehicles being serviced, is stored on site and periodically collected by authorized third party contractors. An additional three aboveground 23 m3 steel tanks, also inside suitable concrete bunding, are present on site. These were originally used as storage of contaminated fuel, but are now empty and no longer in use. Potential environmental impacts and associated social impacts were identified and preventative / enhancement and mitigation measures are provided in the form of an EMP in this report.

  • Agricultural Activities on the Farms Tsumore and Manheim, Tsumeb District
    APP: 00911 AGRICULTURAL ACTIVITIES ON THE FARMS TSUMORE AND MANHEIM, TSUMEB DISTRICT ENVIRONMENTAL ASSESSMENT SCOPING REPORT Assessed by: Assessed for: December 2019 EXECUTIVE SUMMARY Namfo requested Geo Pollution Technologies (Pty) Ltd to undertake an environmental assessment for their existing agricultural activities on farms Tsumore (FMB/01249) and Manheim (FMB/00100/00025) in the Tsumeb District (Figure 1). The farms are located adjacent to each other and are managed as one agricultural unit. Namfo currently irrigates 56 ha on the farm while 60 ha is used for dryland cropping. The main produce are tomatoes, sweetcorn, lettuce, cabbage, sweet melons, potatoes, carrots and onions. Irrigation is from six production boreholes, by means of centre pivot, micro-sprinkler and drip irrigation systems. The main operational activities include: land preparation; planting; water abstraction and irrigation; fertilizer application and pest control; harvesting; and processing and packaging. The environmental assessment is conducted to determine all environmental, safety, health and socio- economic impacts associated with the continued agricultural activities on the farm. Relevant environmental data has been compiled by making use of secondary data and from a reconnaissance site visit. Potential environmental impacts and associated social impacts were identified and are addressed in this report. The project location lies amidst various other agricultural farms and developments. Due to the nature and location of the Namfo’s agricultural activities, some impacts can be expected on the surrounding environment, see summary impacts table below. Regular environmental performance monitoring is thus recommended to ensure regulatory compliance and the implementation of corrective measures when necessary. Namfo’s operations play a role in contributing to the Namibian agricultural sector.

  • An Investigative Study on the Namibian Defence Force's Combat
    AN INVESTIGATIVE STUDY ON THE NAMIBIAN DEFENCE FORCE’S COMBAT READINESS FOCUSING ON ALTERNATIVE POLICY OF TERMINATION AND RETENTION OF EXPERTISE IN THE MILITARY SERVICES A THESIS SUBMITED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF ARTS IN SECURITY AND STRATEGIC STUDIES OF THE UNIVERSITY OF NAMIBIA FACULTY OF ECONOMICS AND MANAGEMENT SCIENCE DEPARTMENT OF POLITICAL AND ADMINISTRATIVE STUDIES BY APPOLOS NDAITWA HAIMBALA 200743112 Windhoek, April 2014 Main Supervisor: Dr. Lesley Blaauw i ABSTRACT National and international peace and security rely immensely on the perceived security dimension of combat readiness. As such, world nations frequently modernise their armed forces in order to achieve a sufficient level of competitive combat readiness in order to act as deterrence against external threats. These actions, however, frequently cause other nations to feel threatened which may result in them embarking on a build-up of the military at public expense. Nevertheless, combat readiness is a pre-requisite for a military’s ability to prevent attacks from a potential aggressor while simultaneously calling for the application of restraining measures in order to prevent wars. In light of the need for militaries to retain a sufficient level of competitive combat readiness, the general findings of this study suggest that there is a requirement to change the retirement condition within Namibia’s public service. This study aims to enlighten both military personnel and the general public on the country’s combat readiness, and ability to quickly deploy in war times. This study applied a qualitative research perspective which adopted a convenient stratified technique. Upon analysing the data, the study indicated that the absence of clear policies on retirement and retention of expertise in the military services hampers the effectiveness of military combat readiness in the Namibian Defence Force.

  • Flags, Funerals and Fanfares: Herer O and Missionary Contestations Ofthe Acceptable, 1900-1940 *
    Journal ofAfrican Cultural Studies, Volume 15, Number l, June 2002 Carfax Publishing Taylor & Franc« Group Flags, funerals and fanfares: Herer o and missionary contestations ofthe acceptable, 1900-1940 * JAN-BART GEWALD (Institute for African Studies, University of Cologne) ABSTRACT The article describes the contested relationship that existed between Herero people and German missionaries in Namibia between 1900 and 1940. 1t is argued that Herero converted to mission Christianity with specific aims and intentions, which were not necessarily the same as those envisaged or intended by German missionaries. The article highlights leisure time, commemorative activities and funerals, and indicates that Herero acquired specific forms of music, dress, comportment, and behaviour from German missionaries. Once these specific forms were acquired they were often transformed and brought to the f ore in ways that were considered unacceptable by the missionaries and settler society in general. The article shows that apart from race there was little difference in the intentions and activities of Herero and German settlers, both ofwhom sought to influence the same'colonial administration. In conclusion it is argued that, in the last resort, what was ofprimary importance in the colonial setting of Namibia between 1900 and 1940 was the issue of race. On a wintry Sunday morning in 1927, a missionary working in the small settlement of Otjimbingwe in Namibia found his early-morning devotional ministrations rudely disturbed by the stridently noisy arrival of a football team from the neighbouring town of Karibib. Borne on trucks bearing flags in the 'colours of the Ethiopian freedom movement' and singing songs, the young men and their supporters began a boisterous day of competition, and ensured that the missionary had but a paltry few church attendants.

Numerous studies have shown that ore formation in Mississippi Valley-type deposits. bears a close relationship with carbonate diagenesis and basin evolution. The application of isotope (Sr , 0, C) techniques as regards to timing and mechanisms of ore-forming processes, as a possible tool in exploration. is especially emphasized in this study. Detailed petrographic and isotope-geochemical investigations were carried out in the Late Precambrian deposits of Berg Aukas. situated just north of the town of Grootfontein. in addition to the Odin Prospect situated to the east of Kombat Mine.
