Geologists protest bill to remove state rock. Begin Slideshow 3 Photo: Michael Macor, The Chronicle Garry Hayes, Professor of Geology at Modesto Junior College, holds a sample of solid serpentine, found along Del Puerto Canyon Road, 20 miles west of Patterson, Ca. on Thursday July 15, 2010.
A bill to remove serpentine as California's official state rock was working its way through the state legislature until geologists heard about it and are now taking offense to the proposal.The bill sponsored by a woman whose husband died of asbestos poisoning is supposed to be a symbolic gesture given that serpentine is the source of asbestos. less Garry Hayes, Professor of Geology at Modesto Junior College, holds a sample of solid serpentine, found along Del Puerto Canyon Road, 20 miles west of Patterson, Ca. on Thursday July 15, 2010.

Geological Survey Fact Sheet 2004-3099 2005 By Cheryl J. Hapke and Krystal R. Green Along central California’s Big Sur coast, the rugged Santa Lucia Mountains descend abruptly into the Pacific Ocean. Maintaining safe access along the Coast Highway is essential for both tourism and the livelihood of local residents. U.S. Ocean Explorer. Serpentinites form when seawater reacts with peridotite - rocks that form the Earth's mantle and have been brought up to the seafloor by tectonic processes.
This picture shows a hand sample of a serpentinite recovered from the Atlantis Massif. Thin fractures in the serpentinite are filled with calcium carbonate. Sample is 16cm wide.

As magma rises towards the surface and pressure decreases, gases are released from the liquid portion of the magma (melt) and continue to travel upward and are eventually released into the atmosphere. Large eruptions can release enormous amounts of gas in a short time. The 1991 eruption of Mt. Pinatubo is thought to have injected more than 250 megatons of gas into the upper atmosphere on a single day. However, even if magma never reaches the surface, gases can often escape continuously into the atmosphere from the soil, volcanic vents, fumaroles, and hydrothermal systems.
Glacial Landforms. SOSE - Coastal Upwelling Online Learning Activity. Description: This set of tutorials will incorporate datasets from a variety of sources to focus on coastal oceanographic processes and their connections to climate and biology.
Learning Objectives: After successfully completing these modules, students should be able to: Understand how multiple physical forces interact to determine water circulation Appreciate the interrelationships between biological and physical processes Describe the Biological Pump and explain its significance, including its role in determining oceanic nutrient distributions Understand why upwelling increases productivity Examine wind conditions to predict upwelling events Identify upwelling events and phytoplankton blooms based on satellite imagery Make connections between local conditions and global consequences.
Pillow lava. Pillow lavas are bulbous, spherical, or tubular lobes of lava.
They form during eruptions with relatively low effusion rates. Slow extrusion gives enough time for a thick crust to form on all sides of a pillow lobe, and prevents individual pillows from coalescing into a sheet. Natural Oil Seeps : Woods Hole Oceanographic Institution. There’s an oil spill every day off the coast of Santa Barbara, Calif., where oil is seeping naturally from cracks in the seafloor into the ocean.
Lighter than seawater, the oil floats to the surface. Some 20 to 25 tons of oil are emitted each day. (Photo by Dave Valentine, University of California, Santa Barbara) What are Oil Seeps? As much as one half of the oil that enters the coastal environment comes from natural seeps of oil and natural gas. How Vasquez Rocks, L.A.'s onetime outlaw hideout, became 'Star Trek's' favorite alien landscape. The mission, from the day “Star Trek” premiered on America’s televisions on Sept. 8, 1966, was ambitious: “to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.”
Where did Gene Roddenberry’s TV series go to find that world? Often as not, it was a piece of alien-looking geology right here in Southern California — amid the jagged, sandstone boulders of Vasquez Rocks Natural Area Park, a Santa Clarita Valley desertscape of prehistoric waves, frozen in time, that has done star turns in Hollywood productions since the 1920s. It’s where Capt. James T. Kirk famously battled a seemingly indestructible green lizard called a Gorn in the episode titled “Arena,” and it represented planet Capella IV, where Kirk and Dr. 3-D Geologic and Seismic Velocity Models of the San Francisco Bay Region.

Sometimes called the “smallest mountain range in the world,” the Sutter Buttes rise almost 610 meters (2,000 feet) above the flat agricultural fields of the Great Valley of central California. Fs2011 3024. Western Region Geology and Geophysics Science Center. The Transverse Ranges Province of southern California is so-named because the mountains, valleys, and geologic structures within this province lie east-west or " transverse to " the prevailingly northwest-trending grain characteristic of southern California.
For example, northwest-trending faults of the Peninsular Ranges Province lend a northwest-oriented topographic and structural grain to that province. Likewise, the Coast Ranges and Sierra Nevada Provinces of southern and central California also are prevailingly northwest-trending. The Transverse Ranges lie athwart this northwest grain. Although referred to collectively as the Transverse Ranges, the province consists of several discrete mountain ranges and intervening valleys, including: Geologists group these discrete landforms within the Western, Central, and Eastern Transverse Ranges.

General Summary The San Gabriel Mountains are a fault-bounded block of ancient crystalline rocks that rises north of the Los Angeles Basin and the upper Santa Ana River Basin. Lake Tahoe Basin Mgt Unit - Learning Center. How Was Lake Tahoe Formed? Although it is commonly believed that Lake Tahoe was formed by the collapse of a volcanic crater, the Basin was actually formed by the rise and fall of the landscape due to faulting. About 24 million years ago the Sierra Nevada block was formed by tremendous uplifting. Two principal faults evolved: the eastern margin created the Carson Range, while the Sierra Nevada developed on the western side. Ccean crust. Geologic Resources » Education.
