One of the biggest questions in the geological history of the western United States is: How old is California's Sierra Nevada? Recent work by a team including Stanford scientists goes a long way to providing an answer, as well as a view into climate history that could assist future climate change projects. The research, available online at GSA Bulletin, used advanced geochemical techniques to investigate three key aspects of the Sierra Nevada history: age, elevation and climate.

Researchers at the University of Utah have been retesting the age of soil and rock strata well known for the fossils they house — specifically, the remains of the earliest dinosaur relatives. The new data, published in the journal PNAS, suggest the first dinosaur species and their earliest relatives, called dinosauromorphs, weren't separated by as large a chronological gap as previously thought.

Recent orbital and rover missions to Mars have turned up ample evidence of clays and other hydrated minerals formed when rocks are altered by the presence of water. Most of that alteration is thought to have happened during the earliest part of Martian history, more than 3.7 billion years ago. But a new study shows that later alteration — within the last 2 billion years or so — may be more common than many scientists had thought.

This is a half-day workshop was developed to provide water utility personnel, engineers, hydrogeologists, regulatory officials and other interested persons in understanding about the sand and gravel and bedrock aquifers their wells are located in and how and why well performance declines over time along with options that are available to rehabilitate your well. The workshop begins with an introduction of the geology and aquifers of New England. From plate tectonics to glacial geology along the effects of weathering that have created the majority of high-yield aquifers located throughout New England. A quick trip through well types, water well terminology, groundwater flow into well screens and a discussion of specific capacity as it applies to sand and gravel and bedrock aquifers. Specific capacity is easy to calculate and use as a measure of the performance of your well, but something that is often overlooked. Moving forward, there is a segment on declining well performance including a discussion of the chemical, physical, and microbiological factors that are the cause for drop in performance in wells. Improving the performance of your well will be discussed by examining physical and chemical methods to rehabilitate your well and improve specific capacity. Understanding the permitting considerations along with the costs of well rehabilitation services will be discussed. The final segment of the workshop will be case studies on well rehabilitation. This will tie together all of the other segments of the workshop.

Earth's mantle, the large zone of slow-flowing rock that lies between the crust and the planet's core, powers every earthquake and volcanic eruption on the planet's surface. Evidence suggests that the mantle behaves differently below 1 megameter (1,000 kilometers, or 621 miles) in depth, but so far seismologists have not been able to explain why this boundary exists. Two new studies co-authored by University of Maryland geologists provide different, though not necessarily incompatible, explanations.

Emissions of methane from the oil and gas industry vastly exceed federal government estimates, according to a definitive study published Dec. 7. The study finds that daily leaks of the potent greenhouse gas from oil and gas wells in Texas' Barnett Shale matched the annual emissions of 8,000 cars. Meanwhile, in California's Aliso Canyon, a natural gas storage site has leaked at least 800,000 metric tons carbon dioxide equivalents of methane since Oct. 23, equal to the annual emissions from 168,421 cars.

Two Florida State University researchers have received grants from the National Academies of Sciences, Engineering and Medicine to study the Gulf of Mexico's ecosystem and better understand its processes, which could help contain future oil spills. Despite a vast body of work on the Gulf of Mexico, there is little information on the circulation and processes that occur at depths below 1,000 meters. A more comprehensive understanding of how these deep current work could lead to better understanding of how contaminants such as oil are transported and also how this process affects the ecosystem at such great depths.

The U.S. Geological Survey is wrapping up work using low-altitude flights over the eastern Adirondacks to map underground rocks and search for rare earth minerals used in cell phones, rechargeable batteries and super magnets. Anji Shah, who heads the project, says the area was identified in a 2010 report on U.S. rare earth resources. Shah said the minerals may be in gravel leftover from extensive iron mining in the late 1800s and early 1900s.

Pioneering new research has shed new light on the causes behind an "ice-age" that took place on Earth around 170 million years ago. An international team of experts have found evidence of a large and abrupt cooling of the Earth's temperature during the Jurassic Period, which lasted millions of years.

More than a century of debate over the age and origin of an outcrop in Southwest Kansas — thought by some geologists to contain the only known Jurassic rocks at the surface in the state — has been resolved, according to a new report by the Kansas Geological Survey at the University of Kansas. The outcrop in question lies at the base of Point of Rocks, a much-anticipated landmark for 19th century travelers along the Santa Fe Trail's Dry Route.
