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

  2. East Africa Rift Location of a continental Rift that began spreading Approximately 20 million Years ago USGS http://pubs.usgs.gov/gip/dynamic/dynamic.html

  3. Currently, the East African Rift is considered a young continental rift zone USGS http://pubs.usgs.gov/gip/dynamic/dynamic.html

  4. If rifting continues, seafloor spreading will occur USGS http://pubs.usgs.gov/gip/dynamic/dynamic.html
