The geology of the Baines Drift area, an explanation of those parts of Quarter Degree Sheet 2228B AND 2229A that lie within Botswana, by G.C. Clark and T.P. Machacha (1982)

During August 1976 and for four months in 1977 the authors geologically mapped those parts of the Directorate of Overseas Surveys sheeets 2228B, D and 2229A that lie within Botswana. The work formed part of a systematic programme of regional mapping of eastern Botswana which the Botswana Geological Survey has been undertaking since 1960. The northern limit of the area mapped is defined by the 22 degrees South latitude, the western limit by the longitude 28 degrees 30 E and the southern and eastern limits by the international boundaries with Zimbabwe and the Republic of South Africa.
