Continental extensional setting for the Archean Belingwe Greenstone Belt, Zimbabwe: comment and reply
Article Abstract:
A group of geologic experts linked the evolution of the Zimbabwe Craton to the Manjeri Formation. Through the use of sedimetological data derived from Manjeri samples, the group concluded that the Zimbabwe Carton is a product an intracontinental sequence which started in Manjeri. Such an assumption, however, drew the interest of some researchers, who claim that the Manjeri Formation has nothing to do with the Zimbabwe Craton phenomenon. No historical or geographic document has so far been produced to confirm that the Manjeri Formation is stratigraphically overlain by the Ngezi Group.

Coeval development of Silurian stromatolite reefs in Alaska and the Ural Mountains: implications for paleogeography of the Alexander terrane: comment and reply
Article Abstract:
The proposed spatial association of continents or continental fragments during Silurian time, particularly the location of the Alexander terrane near northwestern North America, Siberia and Baltica, needs stronger evidence. Specifically, there should be stronger evidence of the distribution of reef-dwelling chambered sponges, the existence of a Uralian Seaway and alternative continental configurations. The lack of pertinent data also bears upon the suggestion of a 'Uralian Seaway' between Siberia, and Laurentia and Baltica.

Nature of the Red Sea Crust: a controversy revisited: comment and reply
Article Abstract:
The conclusions reached by Sultan et al on their studies about the nature of the Red Sea Crust, based from a compilation of remote-sensing, geochemical and geochronological data, is criticized. The arguments are based from the presence of a continental basement in the southern tip of the Red Sea and the Gulf of Suez. Reply reconfirmed the conclusions on the alignment of geologic features along two thirds of the Red Sea with the Arabian and Nubian coastlines within 14 km of juxtaposition.
