Pasadena orogeny and Ventura Basin are consequences of the Pasadena orogeny. The city of Long Beach, California lies within the affected region. Pasadena orogeny Pasadena orogeny is a mountain building event. Conventionally it refers to the formation of mountains in mainly Southern California during the Pleistocene and lasting until the present day; originally it referred to the uplift of the San Gabriel Mountains. The Pasadena orogeny is a major Late Quaternary-modern event of mountain formation, which took place in the middle or perhaps late Pleistocene or to the present-day.

Petermann Orogeny Petermann Orogeny The Petermann Orogeny was an Australian intracontinental event that affected basement rocks of the northern Musgrave Province and Ediacaran (Proterozoic) sediments of the (now) southern Amadeus Basin between ~550-535 Ma. The remains are seen today in the Petermann Ranges. Prior to the Petermann Orogeny, which resulted in exhumation of the Musgrave Block, the Amadeus Basin was contiguous with the Officer Basin in South Australia. The extent and effect of the Petermann Orogen appears to be relatively confined, occurring most pervasively within the central northern-Musgrave Block. Here, older Musgravian (~1200-1150 Ma) fabrics are partially to completely overprinted by sub-eclogite-facies
