Rwh. Butler, LATE PROTEROZOIC RIFT FAULTS AND BASEMENT-COVER RELATIONSHIPS WITHIN THE BEN-MORE THRUST SHEET, NW SCOTLAND, Journal of the Geological Society, 154, 1997, pp. 761-764
Recently proposed models for the tectonic evolution of Northern Scotla
nd, involving lithospheric extension during the late Precambrian, are
supported by new discoveries and interpretations of early normal fault
s within the Moine Thrust Belt, Such structures control the preservati
on of Torridonian sediments beneath the sub-Cambrian unconformity, The
Ben More thrust ramp from basement into the Cambrian cover may have b
een controlled by the early faults. Major synclines within the Ben Mor
e thrust sheet appear as tightened half-grabens and thus are composite
structures, This may require a re-examination of the field relationsh
ips between these folds and the apparently syn-tectonic alkaline intru
sions that have been used to date thrust activity.
