Synopsis: Earth sciences: Geology & mineralogy: Geologist:

But geologists are coming up with alternatives. For example, peridotite, which is a mixture of serpentine

for example, are scarring the rocks to leave telltale evidence of our human influence for geologists to discover many thousands of years into the future.

and 25 known volcanic vents and lava flows reevaluated thanks to dogged work by geologists with the U s. Geological Survey (USGS) and the U s. Forest Service.

It's giving us this serendipitous window on the history of climate in Southeast Alaska for the last 1 million years said Susan Karl a research geologist with the USGS in Anchorage and the project's leader.

And what really captured the geologist's attention were signs that the little volcano squeezed out lava that oozed next to glaciers.

We're convinced now there's probably a whole bunch of green knobs out there covered with timber that may be vents that may have never been mapped said James Baichtal a geologist with the U s. Forest Service based in Thorne Bay Alaska and a project leader.

or something that started in more recent times said Claus-Dieter Hillenbrand a marine geologist with The british Antarctic Survey.

The term Cenozoic first spelled Kainozoic was used originally in an 1840 entry in the Penny Cyclopedia encyclopedia in an article written by British geologist John Phillips. The name is derived from the Greek phrase meaning oerecent life.

Geologists call it the K-Pg extinction event because it marks the boundary between the Cretaceous and Paleogene periods.

and climate change other scientists including marine geologists at The british Antarctic Survey are investigating whether global warming is thinning Antarctica's ice sheets and speeding up the glacier's retreat.

and glaciers and Earth's water resources from the perspective of Earth's paleoclimate geologist Aaron Putnam of the Lamont Doherty Earth Observatory said in a talk at the Columbic Club in New york on March 12 He described his recent

Today Mount st helens and other volcanoes in the Pacific Northwest are monitored closely by geologists at the David A. Johnston Cascades Volcano Observatory in Vancouver.

It was used first in 1839 by Sir Charles Lyell a British geologist and lawyer. As a result of Lyell s work the glacial theory gained acceptance between 1839 and 1846

During this period British geologist Edward Forbes aligned the period with other known ice ages. In 2009 the International Union of Geological Sciences established the start of the Pleistocene epoch at 1. 806 million years before the present.

Two geologists in Arizona are also building a low-cost acoustic detector crowd-funded at about $1000 drawn by the age-old allure of communicating with plants.

But geologists like Lollar also lick rocks. Tiny sediment grains (too small for the eye to see) can be sorted by your sensitive tongue into silt clay or mud.

A sample of that saliva can also help geologists get a good look at a rock with their hand lens a portable magnifying glass.

We have been able to show that the largest volcanic eruption of the last two million years did not significantly alter the climate of East Africa said researcher Christine Lane a geologist at the University of Oxford.

Fieldwork has been a major focus of my career as a paleobiologist and geologist. I really like being outdoors in the field and in exotic places and

and doesn't appear in the Sierra nevada said Jesse Hahm a geologist at the University of Wyoming

Uncertainties remain Eric Steig a glacial geologist at the University of Washington who also studies Pine Island Glacier

and most likely for much longer possibly centuries said lead study author Joanne Johnson a geologist with The british Antarctic Survey.

which provide the first detailed look at Pine Island Glacier's history of surface thinning offer valuable information about past ice sheet behavior said Claire Todd a glacial geologist at Pacific Lutheran

Geologists mostly think these form due to erosion from wind and water as well as from the weathering effects of salt and frost.

Solving the puzzle In the 1960s geologists thought straight up and down-down (vertical) faults bounded the edge of continents similar to the San andreas fault that slices through California.

One month later USGS geologist George Plafker proved him wrong. As a USGS geologist Plafker had studied Alaska's geology each summer since 1953.

But he was in Seattle when the 1964 earthquake struck. After Plafker heard the Space Needle had swayed as the seismic waves raced past he called his boss in Menlo Park Calif. recommending an immediate response.

Before the 1964 earthquake we did not have a unifying theory of how the earth works said Peter Hauessler a USGS research geologist.

But in 1964 geologists believed the Pacific Plate was rotating counterclockwise. In that scenario no new crust was created at underwater volcanic ridges nor was shoved old crust under continents at subduction zones.

But geologists are concerned more about the hazards Alaskans face from more frequent smaller quakes along the Aleutian subduction zone between magnitude 7

Since the 1964 earthquake geologists have learned that the speed of earthquake shaking plays an important role in destruction due to liquefaction.

Geologists use ash beds from volcanoes to date layers of rock. But there is little understanding of how pumice rafts

Robert Anderson, a geologist at the University of Colorado in Boulder, says that Fung's study is part of a larger picture showing that the Arctic is changing far faster

Headed by geologist Ron Oxburgh, former rector of Imperial College London, the inquiry was one of a number established after e-mails sent by scientists at the university's Climatic Research Unit were leaked.

Geologists take drill to Triassic parktourists flock to Petrified forest national park in Arizona to marvel at great glittering logs of petrified wood.

But geologists hope to flock there this month in search of something less visible and more scientifically significant:

says John  Geissman, a geologist at the University of Texas at Dallas and one of the project s leaders."

says Paul  Olsen, a geologist at the Lamont-Doherty Earth Observatory in Palisades, New york,

Geologists have explored the Petrified Forest area since the 1850s, most recently for its rich array of Triassic fossils.

Exactly which Climatologist Climate Scientist Geologist Meteorologist and general weather model do you believe in? If you are so against adding Cosmic and Solar forcing data why?

much as a geologist does the word denudation or an agent expressing the result of several combined actions.

About the size of a small zebra Eurygnathohippus woldegabrieli--named for geologist Giday Woldegabriel who earned his Phd at Case Western Reserve in 1987--had toed three hooves

Members of the two paleontological projects decided to name the species in honor of Woldegabriel a geologist at Los alamos National Laboratory.

Kaushal a geologist is the lead author of a paper about the study published August 26 in the online edition of the peer-reviewed journal Environmental science and Technology.

Cerling and Uno conducted it with geologist Jay Quade a former Utah doctoral student now at the University of Arizona;

Consulting geologist Stewart Redwood determined that the cache consists of a small dacite stone fashioned into a cylindrical tool;

Rocks melt at greater depth than once thoughtmagma forms far deeper than geologists previously thought according to new research at Rice university.

A group led by geologist Rajdeep Dasgupta put very small samples of peridotite under very large pressures in a Rice laboratory to determine that rock can

That has confounded geologists who suspected but could not demonstrate the existence of deeper silicate magma said Dasgupta an assistant professor of Earth science at Rice.

and geologists have been surprised to detect waves slowing down through what should be the mantle's express lane.

Additionally in 1906 individuals living near the Hazel Dell site reported to geologists that cracks from the 1906 earthquake had occurred just where they had 16 years earlier in 1890

More broadly Weldon said having multiple paleoseismic sites close together on a major fault geologists now realize that interpretations gleaned from single-site evidence probably aren't reliable.

This finding meshes nicely with the net energy cliff model proposed by geologist Euan Mearns,
