Algal swamp, marginal and shallow evaporitic lacustrine lithofacies from the late Devonian-early Carboniferous Albert Formation, southeastern New Brunswick, Canada.

Abstract

Describes a complex series of spatially and temporally inter-related alluvial fan, fluvial-deltaic and 'deep' water lacustrine depositional environments. Algal swamp lithofacies are characterized by kerogenous mudstones and inorganically precipitated nodular and phylloid or stromatolitic algal carbonates. Marginal lacustrine lithofacies are represented by two distinctive assemblages, namely carbonate mudflat and shoreface lithofacies. Evaporitic lacustrine lithofacies are characterized by halite, gypsum, glauberite, anhydrite and dolostone with associated shales and siltstones containing molds of evaporite minerals replaced by calcite. -from Authors
