Geochemical and isotopic data from the clastic rocks of the Namurian Lismore Formation in mainland Nova Scotia identify key episodes of tectonic activity during the development of the Maritimes Basin in Atlantic Canada. The Lismore Formation forms part of the Mabou Group and is an upward-coarsening 2500 m thick fluvial sequence deposited in the Merigomish sub-basin along the southern flank of the Maritimes Basin. Based on stratigraphic evidence, the Lismore Formation can be divided into upper and lower members which reflect variations in depositional environment and paleoclimate. The geochemical and isotopic data may also be subdivided into two groupings that primarily reflect varying contributions from accessory phases, clay minerals, or rock fragments. This subdivision occurs 115 m above the base of the upper member. The data from the lower grouping (group A) show an important contribution from underlying Silurian rocks, with a relatively minor contribution from Late Devonian granitoid rocks from the adjacent Cobequid Highlands and possibly metasedimentary rocks from the Meguma Terrane to the south. The data from the upper grouping (group B) reveal a more important contribution from the Cobequid Highlands granitoid rocks. This variation in geochemistry is thought to constrain the age of renewed motion and uplift along the faults along the southern flank of the Maritimes Basin and, more generally, suggests that geochemical and isotopic data of continental clastic rocks may help constrain the age of tectonic events that influence deposition of basin-fill rocks.

The east-trending Cobequid Fault separates pre-Carboniferous rocks of the Cobequid Mountains to the north from Carboniferous clastic rocks along the southern flank of the mountains. A detailed study of the fault zone revealed tie predominance of right-lateral displacements. The orientation of the stress field that existed during deformation along the fault trace was determined by the study of systematic fractures in pebbles within Carboniferous conglomerate. Maximum compressive stress was aligned in a NW–SE direction, being compatible with the orientation of the displacement vectors in the fault zone. Transcurrent movement along the Cobequid Fault occurred in late Pennsylvanian time and involved both Carboniferous and pre-Carboniferous rocks; total displacement is unknown.

Southern Flank

In my previous report (JHS, 1938, p. 247) I spoke of the work being carried on at Syracuse to bring to light the remains of the temple of Apollo. The east, north, and west sides had been freed by then, whilst the southern side was still hidden under seventeenth- and eighteenth-century houses, so that it had never been possible to dig trial trenches through their foundations to ascertain if any part of the temple was preserved there. The demolition of the houses and the excavation under the modern ground level beginning from the south-west angle have fully satisfied our hopes. Five columns of the southern flank of the peristasis have appeared, preserved to a height of over 2 metres, with the stylobate beneath them (Fig. 1): only the angle column had been destroyed during the building of the walls of the Spanish barracks. The cella is equally well preserved, and a third of its total length has already been liberated, although the work is in temporary suspense owing to unsettled disputes with the owners of the houses. The southern flank of the archaic Syracusan temple appears to be in much better condition than the others.
