Mid Continent Rift

At ... geologists disprove theory about what stopped the formation of the Mid Continent Rift (in N America). This rift is generally thought responsible for the dramatic cliffs running along the shore of Lake Superior (where ice melt has scoured away sedimentary layers that once covered it ...

Donald Patten

William suggested looking at the book below after he had read the post at ... The book is by Donald Wesley Patten, 'The Biblical Flood and the Ice Epoch' (Seattle 1966) and in particular chapter V, 'Orogenesis: the Cause of Mountain Uplift' which proposed that a passing cosmic body was capable of causing the landscape of the Earth to rise up. In the news post we learnt that the central Anatolian plateau is detached from its roots in the lithosphere.

Plate Tectonics but different

At ... geophysicists discover evidence for an alternative style of plate tectonics - although it doesn't really sound much like plate movements. J Tuzo Wilson made his reputation in the 1960s by introducing the geology world to the concept of plate tectonics - which is not so long ago. Since then the theory has never been seriously challenged - although heretics still exist.


Scientists claim to have created conditions similar to a so called subduction zone. The transport and release of water during subduction processes is thought to cause volcanic - see article in Nature Geoscience (November 2017) and go to ... As a continental plate slides beneath oceanic crust (or vice versa) it moves into the Mantle - including various minerals and sediments from the ocean bottom. Over time these transform into different compounds but during the process sea water is released from the oceanic crust - inside the Mantle.

Expanding Earth - for and against

At  ... and we have two sides of the argument - with links to papers debunking the idea, and opposite, links to papers enthusiastic of the concept. ... also had a tpod presentation on the expanding earth idea. However, it might be worth considering why plate tectonics does not exist on other planets (as visited by spacecraft recently). Why only the earth? Might it be that earth is occupied by humans and they are highly inventive.

Antarctic Forest

At ... a forest that seems to have been fossilised (growing wood turned to stone) at the end of Permian event has been discovered in the Transantarctic Mountains. What is peculiar is that the press release or study assumes the trees were growing at the South Pole at the time, suggesting they somehow coped with living with 6 months of darkness and 6 months of daylight.

Salt Pond

Research in the Transantarctica Mountains has also thrown up another geological oddity - a pond with one of the saltiest bodies of water on the planet. It is filled with a dense syrupy brine rich in sodium chloride that can remain a liquid well below the freezing point of water ...

A Bend in the Pacific

At ... Hawaii sits at the end of a chain of volcanoes running across the Pacific ocean floor. In the middle of this chain there is a sharp bend of 60 degrees - which geoscientists have struggled to explain, or so we are told in the press release. Research from the University of Oslo now suggest a collision event at the edge of the Pacific plate may be to blame. They arrived at this idea by sticking closely to the orthodox song sheet.

Pacific Basin Anomaly

This one came from an article in American Scientist (volume 105) which was provided by Jovan. Soon after 19th century cartographers captured the relative locations of Hawaii's volcanoes they became aware they lay on two roughly parallel tracks. Since then double tracked volcanoes have been found elsewhere in the Pacific basin. Not only that, they all seem to have switched location between 2 and 4 million years ago. Why? It is now thought Earth's largest tectonic plate, the basin of the Pacific Ocean, started to change direction at this time.
