  1. A Geologic Safari of the East African Rift and the Newark Basin: Why these areas are more alike than you knowPart 3: Focus on New Jersey Margaret H. Benoit The College of New Jersey

  2. “proto” New Jersey USGS http://pubs.usgs.gov/gip/dynamic/dynamic.html

  3. Before spreading initiated, central New Jersey was the location of a continental rift Currently, seafloor spreading is occurring at the Mid-Atlantic Ridge, USGS http://pubs.usgs.gov/gip/dynamic/dynamic.html

  4. Rift basin locations along East Coast associated with the Breakup of Pangaea Modified from Withjack et al., 1988 by Roy W. Schlische, Rutgers University http://geology.rutgers.edu/103web/Newarkbasin/ENArifts.jpg

  5. New Jersey Geology Shale and other lacustrine Sedimentary rocks Intrusive and extrusive basaltic composition igneous rocks Modified from NJ Geological Survey (1994) by Roy W. Schlische, Rutgers University, http://geology.rutgers.edu/103web/Newarkbasin/NJgeol_N1.html

  6. Major fault locations in New Jersey Modified from NJ Geological Survey (1994) by Roy W. Schlische, Rutgers University, http://geology.rutgers.edu/103web/Newarkbasin/NJgeol_N.html

  7. Fault cross sections in the Basin ‘Cool’ colors represent Sedimentary shales, Mudstones, and sandstones ‘Pink’ color represents intrusive igneous dikes and sills Modified from Schlische (1992) and Olsen et al. (1996)

  8. Cross sections of major faults ‘Pink’ color represents intrusive igneous dikes and sills ‘Cool’ colors represent Sedimentary shales, mudstones, and sandstones Schlische (1992) http://geology.rutgers.edu/103web/Newarkbasin/NB_xsects.html

  9. Idealized Half-Graben Modified from Schlische (1994) http://geology.rutgers.edu/103web/Newarkbasin/halfgraben.html

  10. Idealized Sediment deposition during rifting Roy W. Schlische, Rutgers Univesity http://geology.rutgers.edu/103web/Newarkbasin/synsed.html

  12. Igneous contact zone in Flemington, NJ shale hornfels (baked shale from contact metamorphism) basalt Photo by Bryan Molinaro, The College of New Jersey http://www.bryanmolinaro.com/photos/structual/images/P1040800_JPG.jpg

  13. Igneous Rocks from Newark Basin in Piedmont region Highly jointed Orange Mountain basalts at Flemington, NJ Photos by Bryan Molinaro, The College of New Jersey http://www.bryanmolinaro.com/photos/structual/images/P1040804_JPG.jpg http://www.bryanmolinaro.com/photos/structual/images/P1040806_JPG.jpg

  14. Watchung mountains Formed from basaltic Fissure eruptions during Other topographic highs In Piedmont region also Formed from intrusive Diabase sills and dikes NGDC http://www.ngdc.noaa.gov/cgi-bin/mgg/ topo/state2.pl?region=nj.jpg
