GROS MORNE NATIONAL PARK : Gros Morne National Park is a world heritage site located on the west
coast of Newfoundland. At 1,805 km2 (697 sq mi), it is the second
largest national park in Atlantic Canada (surpassed by Torngat Mountains
National Park at 9,600 km2/3,70Gros Morne National Park’s clearly defined boundary encompasses an area
measuring 180,500 hectares. This area is of sufficient size to
completely portray the progression of geological events that took place
when an ancient ocean and the ancient continental margin of eastern
North America were destroyed and uplifted to form a mountain chain
through the action of plate tectonics. Collectively the sequences of
rocks that illustrate this geological evolution are represented by: an
ancient continental crust composed of intensely metamorphosed granite
and gneisses; a continental shelf with tropical carbonate sediments,
containing abundant fossils; a continental slope of thick sequences of
shales inter-bedded with limestone conglomerates, also with abundant
fossils; a complete cross section of oceanic lithosphere including large
exposures of mantle material; and significant sequences of volcanic
rocks of oceanic origin.Happy Journey.
