Independence dike swarm
The Independence Dike Swarm is a major Late Jurassic dike swarm extending over  from the eastern Transverse Ranges northward to the east-central Sierra Nevada in southeastern California, United States. It was described in a paper in 1979. The swarm consists of hundreds of dikes, filled with mafic to felsic rocks and are individually about  in width. These dikes may be the roots of linear-fissure-array supervolcanoes. References
