Jonathan C Matti, PhD
Jonathan is an Emeritus at the Tucson office of the Geology, Minerals, Energy, and Geophysics Science Center. He received a PhD degree in geology from Stanford University in 1978. Since joining the USGS in 1977, he has performed a variety of applied- and basic-research investigations.
Among these, his research into the long-term history of the San Andreas Fault in southern California stands out.

The Southern California Areal Mapping Project (SCAMP) of Geologic Division has undertaken regional geologic mapping investigations in the Lucerne Valley area co-sponsored by the Mojave Water Agency and the San Bernardino National Forest. These investigations span the Lucerne Valley basin from the San Bernardino Mountains front northward to the basin axis on the Mojave Desert floor, and...

Extension and contraction within an evolving divergent strike-slip fault complex: The San Andreas and San Jacinto fault zones at their convergence in southern California Extension and contraction within an evolving divergent strike-slip fault complex: The San Andreas and San Jacinto fault zones at their convergence in southern California
A variety of extensional and contractional structures is produced by strike slip faulting. The variety and extent of the structures are directly related to the kind and extent of geometric complexities of the fault zone or system. The area of convergence of the San Andreas fault zone and the much younger San Jacinto fault zone in the eastern Transverse Ranges is exquisitely complex. We...

A speculative history of the San Andreas fault in the central Transverse Ranges, California A speculative history of the San Andreas fault in the central Transverse Ranges, California
It is generally accepted that the San Andreas fault formed between 4 and 5 Ma and that rocks west of it are now part of the Pacific plate, moving northwest relative to North America at 5 to 6 cm/yr. This model is inconsistent with the geologic record in the central Transverse Ranges. Right-lateral shear began in the vicinity of the San Andreas fault system in early Miocene time. The San...

Chapter 6: Chronology of displacement on the San Andreas fault in central California: Evidence from reversed positions of exotic rock bodies near Parkfield, California Chapter 6: Chronology of displacement on the San Andreas fault in central California: Evidence from reversed positions of exotic rock bodies near Parkfield, California
This chapter presents a synthesis of data pertaining to post-early Miocene slip on the San Andreas fault in central California and suggests a three-phase evolition of the San Andreas system. The cricial evidence that supports the three phases of evolution conies from the reversed positions of two exotic rock fragments in the vicinity of Parkfield, California. The three-phase evolution of...
