But this is a false premise; new discoveries in the various branches of science have either highlighted gaps in our knowledge or have pointed the way to investigation in new fields. -

The Ahlmannryggen Group, the Viddalen Formation and the Associated Igneous Rocks in the Viddalen Area, Western Dronning Maud Land, Antarctica
THE AHLMANNRYGGEN GROUP, THE VIDDALEN FORMATION AND THE ASSOCIATED IGNEOUS ROCKS IN THE VIDDALEN AREA, WESTERN DRONNING MAUD LAND, ANTARCTICA by JOHANNES HENDRIK BREDELL Submitted in partial fulfilment of the requirements for the degree of MAGISTER SCIENTIAE in the FACULTY OF SCIENCE OF THE UNIVERSITY OF PRETORIA, PRETORIA October, 1976 Digitised by the University of Pretoria, Library Services, 2016. © University of Pretoria (i) ABSTRACT Nunataks within an area of approximately 3 400 km2 between latitudes 71°50' and 72°35' south and longitudes 1°30' and 4°00' west were mapped geologically by the 12th South African National Antarctic Expedition during the summer of 1971-72. The area is underlain mainly by subhorizontal arenaceous and argillaceous sediments, extensively intruded by thick mafic sills and dykes of Precambrian age. An isolated succession comprising agglomerate, tuff and lava flows with intercalated sediments in its upper part is exposed in the east and south. A new lithostratigraphic subdivision is proposed, based on detailed investi gation of field relationships combined with subsequent petrological studies and radio metric age determinations. The oldest rocks in the area belong to the Pyramiden Formation which consists mostly of feldspathic graywacke and siltstone. Correlates of this formation were discovered at Kjolrabbane, Babordsranten and at Nashornet and Viddalskollen. At the latter locality the sequence is subdivided into a Lower Member, 140 m thick, deposited under low-energy, deep-water conditions, and an Upper Member, 250 m thick, which was deposited in shallower water under higher energy con ditions .. The overlying Grunehogna Formation has the widest distribution of all sedimentary formations in the area and consists of alternating persistent beds of light-coloured arenite and dark-coloured argillite. -
