The eologic History of New York State The Mesozoic eologic Provinces NY Region Timescale and geologic provinces of NY-NJ Mesozoic Rock Formations in the NY Region Mesozoic rock formations in the NY region Early Jurassic Late Triassic Late Cretaceous
Triassic - Jurassic Rock Newark Basin Late Triassic Pangea begins to rift apart. Line of hotspots develops beneath old suture. Africa and South America pull away from North America. Tension in crust forms rift basins.
Mesozoic Rift Basins Rift basin geology Bounding normal fault. Volcanism (basaltic fissure eruptions). Alluvial fan conglomerates. Deposition of sediments in river systems. Deposition of sediments in lakes. Fossils of terrestrial animals and plants. Northern End of the Newark Basin Watchung lava flows Ramapo fault Palisades intrusive sheet Lower Jurassic Upper Triassic
