Available in PDF, EPUB and Kindle. Book excerpt: The San Andreas Fault (SAF) near Parkfield, CA moves by a combination of aseismic creep and micro-earthquake slip. Measurements of in situ stress orientation, stress magnitude, and heat flow are incompatible with an average shear stress on the SAF greater than approximately 20 MPa. To investigate the micro-mechanical processes responsible for the low strength and creeping behavior, gouge samples from the 3 km-deep scientific borehole near Parkfield (the San Andreas Fault Observatory at Depth, SAFOD) are sheared in a triaxial rock deformation apparatus at conditions simulating those in situ, specifically a temperature of 100°C, effective normal stress of 100 MPa, pore fluid pressure of 25 MPa, and a Na-Ca-K pore fluid chemistry. The 2 mm-thick gouge layers are sheared to 4.25 mm at shear rates of 6.0, 0.6, 0.06, and 0.006 mu m/s. The mechanical data are corrected for apparatus effects and the strength of the jacketing material that isolates the sample from the confining fluid. Experiments indicate that gouge is extremely weak with a coefficient of friction of 0.14, and displays velocity and temperature strengthening behavior. The frictional behavior is consistent with the inferred in situ stress and aseismic creep observed at SAFOD. The low frictional strength likely reflects the presence of a natural fabric characterized by microscale folia containing smectite and serpentinite.

Available in PDF, EPUB and Kindle. Book excerpt: The authors of the ten chapters in this volume critically examine the geologic evidence that constrains timing and magnitude of movement on various faults of the San Andreas system, and they develop and discuss paleogeologic reconstructions based on these constraints. The volume offers new insight into the evolution of the San Andreas fault system,

Download or read book The San Andreas Fault Zone written by William A. Szary and published by . This book was released on 2019-10-21 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The San Andreas Fault Zone covers almost the entire length of western California. Some sections are simple while others are more complex extending from the Gulf of California through the Salton Trough into the San Gabriel and San Bernardino Mountains, through the Carrizo Plain into Parkfield, on into the San Francisco Bay, Point Reyes, and ending in the Mendocino Triple Junction. This book attempts to characterize the geologic structure, geophysics, and stratigraphy on both sides of the fault. Chapter 1 presents an overview of the setting of the San Andreas Fault System. Chapter 2 discusses the Salton Sea Trough, the Gulf of California, and the Imperial Valley. Chapter 3 presents the fault zone through the Transverse Ranges, mainly consisting of the San Gabriel and the San Bernardino Mountains. Chapter 4 addresses the creeping segment of the Carrizo Plain, Cholame, and Parkfield. Chapter 5 focuses on the San Andreas-Calaveras Fault junction along the San Benito segment. Chapter 6 discusses the South San Francisco Bay area, mainly in Santa Clara County before addressing the San Francisco Bay in Chapter 7. Chapter 8 focuses on the Point Reyes Peninsula, providing some details on the stratigraphy and structure on the peninsula. Chapter 9 closes out with a seismic review of the Mendocino Triple Junction and its interactions with the Pacific, Gorda, and North American plates.

This book was released on 2010-01-01 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The San Jacinto right-lateral strike-slip fault zone is crucial for understanding plate-boundary dynamics, regional slip partitioning, and seismic hazards within the San Andreas fault system of southern California, yet its age of initiation and long-term average slip rate are controversial. This synthesis of prior and new detailed studies in the western Salton Trough documents initiation of structural segments of the San Jacinto fault zone at or slightly before the 1.07 Ma base of the Jaramillo subchron. In Special Paper 475, five new estimates of displacement are developed using offset successions of crystalline rocks; distinctive marker beds in the late Cenozoic basin fill; analysis of strike-slip-related fault-bend folds; quantification of strain in folds at the tips of dextral faults; and gravity, magnetic, and geomorphic data sets."--Publisher's website.
