University of Calgary University of Calgary-led research is first of its kind, uncovering the origin of oilsands sediment They're called the Alberta oilsands but most of the sand actually came from the Appalachian region on the eastern side of the North American continent, a new University of Calgary-led study shows. The oilsands also include sand from the Canadian Shield in northern and east-central Canada and from the Canadian Rockies in western Canada, the study says. This...

2013-12-07 08:52:40

Science China Press In a recent study, large numbers of bryozoan and other typical marine fossils were discovered for the first time in the thick limestone layers and lenses of the upper part of the Linxi Formation of the Guandi section, Linxi County, eastern Inner Mongolia. These marine fossils provide the first evidence for the Xingmeng area being in a marine or mainly marine environment at the end of the later part of the late Permian. This paper, entitled "Discovery of marine...

New Test Helps With Understanding Earth’s History And Resources
2012-12-06 10:18:32

University of Florida A new study co-authored by a University of Florida researcher provides the first direct chronological test of sequence stratigraphy, a powerful tool for exploring Earth´s natural resources. The model allows geologists to better understand how sedimentary rocks are related to one another in time and space and predict what types of rocks are located in different areas. The information may help scientists more reliably interpret various aspects of Earth´s...

Rapid advances in the new and developing field of restoration sedimentology will be needed to protect the world's river deltas from an array of threats, Indiana University Bloomington geologist Douglas A. Edmonds writes in the journal Nature Geoscience. The commentary, published this week in the November issue, addresses the fact that land is disappearing from river deltas at alarming rates. And deltas are extraordinarily important: They are ecologically rich and productive, and they are...

The mystery of how an abundance of fossils have been marvelously preserved for nearly half a billion years in a remote region of Africa has been solved by a team of geologists from the University of Leicester's Department of Geology. They have established that an ancient wind brought life to the region "“ and was then instrumental in the preservation of the dead. Sarah Gabbott, Jan Zalasiewicz and colleagues investigated a site near the Table Mountains in South Africa. Their findings...
