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.
Fracture zones extend past the transform faults, away from the ridge axis; seismically inactive (because both plate segments are moving in the same direction), they display evidence of past transform fault activity, primarily in the different ages of the crust on opposite sides of the zone.
