Significance of a Meguma mass transport deposit in Halifax, Nova Scotia

TL;DRAbstract

Portions of the Meguma Supergroup in Nova Scotia have been interpreted as originating in slope, rift, and shelf environments; indications of paleoslope have important implications for tectonic environment. The Bluestone formation represents the upper part of the Halifax Group in the Halifax Peninsula and adjacent mainland. Despite the overprint of regional deformation and contact metamorphism, most outcrops display well-bedded metasedimentary rocks with Bouma sequence structures. Cleavage and an intersection lineation are related to the west-southwest-plunging Point Pleasant syncline. In contrast, at Chain Rock, quartzose and calc-silicate hornfels representing originally coarser metasedimentary rocks occurs as isolated blocks containing rootless folds with curved axial traces. Along strike at the Martello Tower, folds display curved hinges that plunge both west-southwest and east-northest. At Fort Ogilvie, ovoid metasandstone blocks occur in an originally fine-grained matrix. The unit
