Abstract:

The eugeosynclinal Exploits Group (Exploits Series of Heyl, 1935, 1936) of northeast Newfoundland is redefined on the basis of new mapping and is assigned a pre-Llanvirnian to early Llandoverian age. The group is subdivided into five new formations and one old, plus one unnamed argillite unit: from base to top, the Tea Arm Volcanics, Saunders Cove Formation, New Bay Formation, Lawrence Head Volcanics, Lawrence Harbour Shale (old name), unnamed argillite unit, and Point Leamington Graywacke. Intertonguing relations show that older Exploits Group strata are equivalent to the Wild Bight Group west of the Bay of Exploits. Lushs Bight Group strata north of the Lukes Arm fault are interpreted to have time and lithostratigraphic equivalents in the older Exploits Group rocks. The name "Boones Point Complex" is proposed for a mylonitized lithic band which lies within and adjacent to the Lukes Arm fault zone.
