    Preliminary bedrock geology for NTS 95D/6 (Otter Creek area), southeast Yukon L. Pigage Preliminary bedrock geology for NTS 95D/6 (Otter Creek area), southeast Yukon Lee C. Pigage1 Yukon Geological Survey Pigage, L.C., 2008. Preliminary bedrock geology for NTS 95D/6 (Otter Creek area), southeast Yukon. In: Yukon Exploration and Geology 2007, D.S. Emond, L.R. Blackburn, R.P. Hill and L.H. Weston (eds.), Yukon Geological Survey, p. 237-255. ABSTRACT The Otter Creek area contains sedimentary and volcanic strata of the ancient North American miogeocline: Neoproterozoic to Lower Cambrian shale (Narchilla Formation) and siltstone (Vampire Formation); Late Cambrian to Middle Ordovician argillaceous to massive limestone (Rabbitkettle Formation) and dolostone (Sunblood Formation); Cambrian to Ordovician basalt and associated diabase; Silurian to Devonian MacDonald carbonate platform strata (unit SDc-south) and Selwyn basin shale (Road River Group-north); and thinly bedded silty shale likely of the Devonian to Carboniferous Besa River Formation. The rocks are deformed by six mappable north-trending, east-verging, asymmetric, macroscopic folds with amplitudes of 500-2000 m. Argillaceous and silty units contain a pervasive, axial-planar slaty cleavage. Shortening caused by the folding is about 25%. The Narchilla Formation is structurally emplaced upon Upper Cambrian-Devonian sedimentary rocks on the western margin of the map area, along an east-verging thrust fault with unknown displacement. Late northeast-striking normal faults preserve younger stratigraphic units to the south. Deformation is poorly constrained to the Mesozoic-Cenozoic Cordilleran orogeny. Four epigenetic(?), stratabound zinc±lead±barite deposits and showings occur at the stratigraphic contact between massive limestone and argillaceous limestone within the Rabbitkettle Formation.

The emerald is generally found in quartz–carbonate veins with mm-scale alteration haloes of muscovite and carbonate. The skarn is hosted within the Cambro-Ordovican Rabbitkettle Formation, which overlies black shales of the Devonian Earn Group. Skarn and subsequent quartz–carbonate veins are the result of contact metamorphism related to the emplacement of the adjacent 93 Ma Lened pluton of the Selwyn Plutonic Suite. Fluid-inclusion studies reveal the presence of two distinct fluids, a CO2-bearing fluid related to emerald precipitation and a brine limited to subsequent crystallization of quartz. The CO2-bearing fluid is dominantly a dilute aqueous brine with approximately 4.5 mole % CO2 and minor amounts of CH4, N2, and H2S. The pressure of formation is limited by estimates of the maximum lithostat to less than 320 MPa.

  • When Life Got Smart: the Evolution of Behavioral Complexity Through the Ediacaran and Early Cambrian of Nw Canada
    Journal of Paleontology, 88(2), 2014, p. 309–330 Copyright Ó 2014, The Paleontological Society 0022-3360/14/0088-309$03.00 DOI: 10.1666/13-066 WHEN LIFE GOT SMART: THE EVOLUTION OF BEHAVIORAL COMPLEXITY THROUGH THE EDIACARAN AND EARLY CAMBRIAN OF NW CANADA CALLA CARBONE AND GUY M. NARBONNE Department of Geological Sciences and Geological Engineering, Queen’s University, Kingston, ON, K7L 3N6, Canada, ,[email protected].; and ,[email protected]. ABSTRACT—Ediacaran and early Cambrian strata in NW Canada contain abundant trace fossils that record the progressive development of complex behavior in early animal evolution. Five feeding groups can be recognized: microbial grazing, deposit-feeding, deposit-feeding/predatory, filter-feeding/predatory, and arthropod tracks and trails. The lower Blueflower Formation (ca. 560–550 Ma) contains abundant burrows that completely cover bedding surfaces with small (~1mm diameter) cylindrical burrows that were strictly restricted to microbial bedding surfaces and exhibited only primitive and inconsistent avoidance strategies. The upper Blueflower contains three-dimensional avoidance burrows and rare filter- feeding or possibly predatory burrows, suggesting increased behavioral responses in food gathering that marked the beginning of the agronomic revolution in substrate utilization. Cambrian strata of the Ingta Formation contain systematically meandering burrows and more diverse feeding strategies, including the onset of treptichnid probing burrows that may reflect predation. These observations imply that Ediacaran burrowers were largely characterized by crude, two- dimensional avoidance meanders that represented simple behavioral responses of individual burrowers to sensory information, and that the subsequent development of more diverse and complex feeding patterns with genetically programmed search pathways occurred during the earliest stages of the Cambrian explosion.
