One of the basic challenges that faces Namibian society as it emerges from colonial times is the issue of inequality and the oppression of women and girls. The San girl-child is no exception in this regard. San women in Namibia are subject to low socio- economic status and the poorest rates of formal education. San girls who enrolled at primary school hardly make it to secondary schools because of their significantly high dropout rate. This is prevalent among girls in particular as a result of early pregnancies, marriages and other related factors. The practice of early marriage is still prevalent, despite the Namibian government’s efforts to address the issues of inequality and oppression of women. For example, article 10 of the Namibian Constitution that stipulates that all persons are equal before the law. It also prohibits any discrimination on ground of sex, race etc. Moreover, in spite of the adoption of some National Gender legal Frameworks and the signing of various regional and international gender instruments, barriers to gender equality, equity and education attainment for the San girl child remain in place. However, in Namibia as in many developing countries researches onto early marriage has largely been neglected and data on various aspects of early marriage is minimal. Hence, the study aimed to shed light on the impact of early marriages on the education attainment of the San-girl child in particular as well as to draw the attention of policymaker and the Omaheke region community attention tothese harmful traditional and socio- economic practices, such as early marriage. For my study on the perceptions of selected respondents of the impact of early marriage on the education attainment of the San-girl child, I used aqualitative research approach and employed a semi-structured interview technique as my main data collection tool. The study revealed that early marriage impacts negatively on the education attainment of the San girl-child and that this undermines the status of San girls and constitutes a barrier to gender equality and equity attainment in their lives.

The study seeks to document the development of the alternative press in Namibia from 1960 to 1990. It traces the reasons for its emergence and outlines the stated aims and objectives in order to illustrate its attempts to nurture a culture - of colonial resistance. It is argued that structural factors such as funding, distribution, advertisements and ownership enabled the alternative press to operate outside the South African apartheid hegemony. The study explains how the intellectuals used the alternative press in their attempts to mobilise and organise colonised Namibians for social change. They did this by formulating and disseminating ideologically constructed discourses (messages) which challenged the colonial discourse. These messages were produced and directed towards a specific audience, the masses to whom the intellectuals were organically linked. Their primary news definers were also drawn from the ranks of these masses. It is further argued that the alternative press came to represent the colonised masses by voicing their needs and aspirations which were marginalised by the mainstream colonial media. Finally, a relatively detailed analysis of the content, the language used and the'messages carried by the alternative press has been made to demonstrate its political agenda, which was to empower the masses to achieve their objective - the attainment of political independence. These issues are analyzed against a background of theoretical frameworks which seek to explain how subordinated groups and classes in a state of domination sought to establish alternative channels of communication in the creation of a counter hegemonic order.

The Matchless Amphibolite Belt (Damara Orogen, Namibia) hosts several volcanogenic-exhalative, sediment-hosted stratiform cupriferous pyrite deposits. These are thought to be related to submarine volcanism during the early evolutionary stages of a narrow Damaran ocean, the Matchless Trough. The mineralized bodies examined (Ongeama, Ongombo and Matchless West Extension) are deformed and metamorphosed to low-medium grade (greenschist-amphibolite facies). They are associated with metapelite and amphibolite country rocks, and crop out as prominent limonite-rich gossans. The elongated shape of the sulphide bodies suggests a structural control. The mineralization normally consists of a variably developed massive sulphide portion, either quartz-, talc- or amphibole-bearing, and a stratigraphically overlying, extensive horizon of sulphide- and baryte-bearing exhalite (magnetite quartzite and less common talc- and actinolite-bearing schists). Lateral and vertical mineralogical changes within the mineralization match with significant variations in the element distribution. A metamorphosed and deformed alteration pipe, indicating the position of the fluid conduit, can be recognized in association with some ore bodies. The formation of quartz-muscovite and chlorite alteration envelopes (Ongeama, Matchless West Extension) and the presence of subtle mineralogical changes (Ongombo) in the immediate wallrocks, accompanied by extensive redistribution, leaching and introduction of elements from outside, suggest the hydrothermal metasomatic origin of the alteration zones. Element zoning within the mineralized bodies can be related to the original position of the vent, possibly coinciding with the intersection of the axis of the alteration pipe with the sulphide body. Cu, Zn, Au (pro parte) and Mo are enriched proximal to the vent, whereas Pb, Ba, Mn, Ag, Au, Sn, Bi and W enrichment characterizes the distal facies of the mineralization. In spite of the obliterating and disrupting effects of the regional dynamo-metamorphism, the element distribution within the mineralization and alteration zones examined is comparable with the geochemical trends observed in present-day mineralizing systems in early- stage oceanic environments (e.g. Guaymas Basin). During exploration for blind volcanogenic mineralization, the detection of hydrothermally altered rocks is fundamental in indicating the proximity to the mineralization. The localization of the alteration zone is also important in the interpretation of the regional geology of the explored area: in deformed terrains the assessment of the stratigraphic position of the alteration zone, relative to the mineralization, helps in establishing the polarity of the sequence.

The late Proterozoic volcanic and sedimentary sequence in the Dordabis area SWA/Namibia has been named the Dordabis Formation and subdivided, on the basis of field, petrological and petrographic evidence, into the Opdam and Bitterwater Members. Relict phases including augite and minor plagioclase only occur in the Bitterwater metalavas, as recrystallisation is complete in the Opdam metal avas. The composition of the relict feldspars ranges from labradorite in the ophitic basalts to oligoclase in the blastoporphyritic metalavas. The feldspars in the Opdam member are albitic in composition (An content 0,0 to 1,7) . Epidote compositions are typical of those occurring in metabasic rocks. Samples with high-iron whole-rock compositions are accompanied by high concentrations of Fe3+ in concomitant epidotes. Sixty three samples were analysed using X-ray fluorescence spectrometry to determine concentrations of major and 16 trace elements. Although greenschist facies metamorphism, metasomatism and shearing have produced scatter in the more mobile element concentrations, variation trends in other elements closely resemble modelled low-pressure fractional crystallisation trends. The Dordabis metalavas are petrologically classified as sub-alkaline, tholeiitic continental basalts. Low K/Rb ratios and low ratios of less incompatible to more incompatible elements probably reflect a source that has either been metasomati ca lly enriched or that has undergone little previous partial melting. Overlapping whole-rock variation trends indicate that the generally more evolved Opdam and primitive tholeiitic Bittenwater lavas are cogenetic. A comparison of the Dordabis Formation with the Sinclair Sequence and the Koras Group shows that their ages, petrology, petrography, associ a ted sedimentary suites and depositional environments are similar. It is concluded that they may possibly be coeval equivalents.
