Gowan1, Lu Niu1, Gregor Knorr1, and Gerrit Lohmann1 1Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven, Germany Correspondence: Evan J. Gowan ([email protected]) Abstract. The ice-substrate interface is an important boundary condition for ice sheet modelling. The substrate affects the ice sheet by allowing sliding through sediment deformation and accommodating the storage and drainage of subglacial water. We present three datasets with different geological parameters for the region that was covered by the ice sheets in North America, including 5 Greenland and Iceland. The first dataset includes the distribution surficial sediments, which is separated into continuous, discontinuous and predominantly rock categories. The second dataset includes sediment grain size properties, which is divided into three classes: clay, silt and sand, based on the dominant grain size of the glacial sediments. The third dataset is the generalized bedrock geology. We demonstrate the utility of these datasets for governing ice sheet dynamics by using an ice sheet model with a simulation that extends through the last glacial cycle. Changes in ice thickness by up to 40% relative to 10 a reference simulation happened when the shear friction angle was reduced to account for a weaker substrate. These datasets provide a basis to improve the basal boundary conditions in ice sheet models.

Developing exploration vectors towards Sudbury breccia- hosted Cu-Ni-PGE mineralization is inhibited by an insufficient understanding of the relative contributions of footwall lithologies versus impact melt. By combining whole-rock geochemistry, field observations, statistical modelling and petrography, this study has determined that Sudbury breccia is a parautochthonous shock melt, which does not require a melt sheet contribution.

The information in this report supports Ontario Power Generation’s (OPG) proposed Deep Geologic Repository (DGR) project at the Bruce nuclear site in the Municipality of Kincardine, Ontario. The report draws information from southern Ontario and the neighbouring states of Michigan, Ohio, Pennsylvania and New York to present a synthesis of current scientific understanding of the Precambrian-Paleozoic sequence within the Regional Study Area (RSA) surrounding the Bruce nuclear site. The purpose of the regional geomechanical review is to present a regional understanding of the geomechanical properties of the deep sedimentary formations that will host and enclose the proposed DGR as they relate to the ability of the sedimentary sequence to isolate and contain Low and Intermediate Level radioactive waste.

Fig Tree Group, Barberton Greenstone Belt, Swaziland Supergroup, South Africa, ~3.26-3.23 Ga (Veizer et al. 1989b) The depositional setting is considered to be marine deepening from south to north from shallow- platformal to deep-water facies (Lowe 1980, 1982; Paris et al. 1985; Brandl et al. 2006). The middle part of the 3.26-3.23 Ga Fig Tree Group (the Mapepe Formation; Armstrong et al. 1990; Byerly et al. 1996; Kröner et al. 1991) contains a section of interbedded dolomite and chert 30 to 50 m thick in the Barite Syncline (Heinrichs and Reimer 1977) at the southern edge of farm Heemstede 378JU. The sequence contains unquestionable sedimentary textures and structures, which have been described in Lowe and Knauth (1977; locality 5), Heinrichs and Reimer (1977), and Bao et al. (2007), indicating deposition above the fair-weather-wave base. 2. Woman Lake Assemblage, Uchi Greenstone Belt, Ontario, Canada, ~2.87-2.86 Ga (Veizer et al. 1989b) The geology of the Woman Lake area of the Uchi Greenstone Belt has been summarized in Hofmann et al. (1985). Grey siliceous, stromatolitic limestones from SE Shabu Lake, Woman Lake, and Confideration Lake that experienced greenschist facies metamorphism and cap the mafic to felsic volcanic cycle were analyzed. The ~2600 m thick cycle starts with amygdaloidal pillowed basaltic flows grading to subaqueous, intermediate pumice flows, felsic tuffs, lapilli- tuffs, and finally felsic tuff, indicating local subaerial volcanism in a caldera setting (Hofmann et al. 1985). Stromatolitic limestone, up to 60 m in thickness, contains stratiform structures with corrugated laminae; 2) small hemispheroidal mounds; and 3) columnar structures; all indicating shallow-water setting within the photic zone.

Rogojina, A.A. Mohajer and N. Eyles, Seismican Geophysical Limited, under contract to the Atomic Energy Control Board. ABSTRACT Increasing concern with the potential earthquake hazard in southern Ontario has focused attention on neotectonic structures affecting bedrock. Within the boundaries of the metropolitan Toronto area (632 km2), about 2500 fracture orientations have been measured in more than 70 bedrock outcrops. An east-northeast systematic fracture set and an abutting orthogonal truncated fracture set constitute the most commonly-oriented fundamental fracture system in the study area. The east-northeast systematic fracture set may be the product of the current compressive stress field combined with regional uplift, but this should be confirmed by further field investigation. Anomalous fracture patterns were identified at the periphery of Metropolitan Toronto, specifically along the West Humber and Rouge rivers. Four post- glacial pop-ups were identified within Metro Toronto. Careful mapping and description of these pop-ups show a possible relationship with the contemporary principal stresses in the area and the local fracture pattern.
