developed by geologists.»
Your readers may want to know that the interpretation and analysis provided
by geologist Tom Rockwell, and on which the story is based, is in our view both flawed and highly editorialised.
Because the temples incorporate pristine examples of local corals, Kirch and Sharp tried a method often used
by geologists called uranium - series dating.
One of those groups is SkyTruth of Shepherdstown, W. Va.,
founded by geologist John Amos in 2001 to monitor the effects of human activity on the environment using remote - sensing and mapping technologies.
An intraplate fault like this generally produces earthquakes much less frequently than those at the boundaries of tectonic plates, like California's San Andreas Fault, and tends to be less well
understood by geologists.
The shape and chemical composition of the mounds, called stromatolites, match those formed by modern bacterial communities living in shallow seawater, says a team led
by geologist Allen Nutman of the University of
First
noted by geologists more than 130 years ago, these deposits have long been recognized as strange, says Christine Siddoway, a geologist at Colorado College, Colorado Springs.
In 1998, a team led
by geologist Birger Rasmussen of the University of Western Australia discovered microscopic drops of fluid oil preserved within mineral grains (similar to gas bubbles trapped in an ice cube) in rocks more than 3 billion years old in Australia's Pilbara region.
Microscopic globules of graphite in the rock, documented in 1999
by geologist Minik Rosing at the University of Copenhagen, are unusually low in a heavy carbon isotope that gets excluded when inorganic carbon is converted into living material.

by geologists over the past 30 years.
They found that Anthropocene strata are often thin — but also that they are globally distributed and may be clearly
recognised by geologists.

This was a known
hazard by geologists because in 2012 and 2013 large chunks of rock fell from the structure into the ocean, prompting a study of its stableness.
On a slight tangent, there was an excellent documentary called «Men of Rock»
presented by the geologist Prof Ian Stewart, which profiled the work of Scottish scientist James Croll who originally came up with the theory of climatic change from orbital forcing.
He is the author of Heaven and Earth, Global Warming: The Missing Science Youtube link: Climate Change Explained by Geologist
So, when Clarke et al emphasize the importance of considering time scales that are considered to be long by politicians, but nearly
instantaneous by geologists, that message falls on very receptive ears.
The controversy did provoke studies
by geologists who would eventually show that the other great extinctions of the past, some even worse than the doom of the dinosaurs, had been caused by massive injections of greenhouse gases from volcanic outbursts — an all too relevant demonstration of the power of the gases.
