n-Dodecyl Mercaptan. Normal dodecyl mercaptan (n-dodecyl mercaptan, 1-dodecanethiol, lauryl mercaptan, NDDM, CAS # 112-55-0) is used in many diverse applications. In free-radical polymerization systems, it acts as a chain transfer agent to control molecular weight. A variety of antioxidants and stabilizers are produced from it as a chemical intermediate.
San Andreas Fault. The San Andreas Fault is the transform boundary between the North American Plate and the Pacific Plate. During the 1906 San Francisco earthquake the northern section of the San Andreas Fault slipped northward along the fault from San Juan Bautista to Cape Mendocino, a total of 296 miles (477km). transform boundary is a fault zone where two plates slide past each other horizontally. Most transform faults are found in the ocean where they offset spreading ridges creating a zigzag pattern between the plates.
Map of the San Andreas Fault, showing relative motion. The San Andreas Fault is a continental transform fault that extends roughly 1300 km (810 miles) through California. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal).ecent studies of past earthquakes indicate that there is a correlation in time between seismic events on the northern San Andreas Fault and the southern part of the Cascadia subduction zone (which stretches from Vancouver Island to northern California).
