Its outcrops were interpreted as the core of a regional syncline and, accordingly, a stratigraphic sequence was erected. We question this interpretation and show by both geological and geophysical investigation that this basaltic band does not occupy the core of a syncline but instead forms a sheet in the folded Archean sequence. On this basis, the stratigraphic sequence is revised. This content is PDF only. Please click on the PDF icon to access.
