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.
The San Andreas fault is one of only a few examples of a transform boundary between two tectonic plates that is exposed on a continent. Some other continental transforms are the Alpine fault in New Zealand and the Dead Sea Transform fault system in the Middle East.he remainder is expressed by displacement along other, subparallel faults such as the Imperial and the San Jacinto fault zones in southern California. The San Andreas fault zone is a transform boundary between two tectonic plates, the North America plate and the Pacific plate.
