Sketches of the TS II - TS III unconformity in the Argana and Fundy basins: A, Location map (p.i., Pinnacle Island of the Five Islands chain; l.e., Lower Economy and Carrs Brook area, both Colchester County, Nova Scotia; B, Field sketch map of tidal outcrop of TS II - TS III unconformity, south side of Pinnacle Island; C, Map based on aerial photographs and field reconnaissance of the tidal outcrops in the Lower Economy and Carrs Brook area showing the pre-rift and TS II - TS III unconformities (land geology from Donohoe and Wallace, 1982); D, Scetch of photograph of the Timesgadiouwine (TS II) - Bigoudine (TS III) (from Olsen, 1997).
Comparison of boundary sections, lower TS IV, in the Argana and Fundy basins with sample positions. The position of the Triassic-Jurassic boundary is based on the samples shown in bold.
Qualitative conceptual diagram showing the main influences on the development of the Argana and Fundy basins. Ages are largely based on correlation with the Newark basin. Water depth for TS II of Fundy basin based interpretation of seismic lines. Abbreviations under water depth and climate are: F, fluvial; FL, fluvial and shallow water lacustrine; SL, shallow lacustrine; DL, deep, perennial lake; +E, arid with abundant eolianites; -E, less arid with rare eolianites; -W; slightly humid with much bioturbation; +W, more humid. Note that these classes are meant to reflect the average state. We have not attempted to show high-frequency fluctuations between extremes.
