The Seychelles Enigma

During the last interglacial, herewith dated 125,000 years ago average global temperatures, it is said, were not a lot different than today - yet large areas of what are now coastal zones, sometimes with great cities, are thought to have been under water - see http://phys.org/print339957733.html

Dinosaur remains on the Isle of Wight

AQt http://phys.org/print339753649.html ... fossils from the Early Cretaceous period can be found in some parts of the Isle of Wight - the age of the dinosaur. Brook Bay is one such location - but there are many collections out there in private hands and fossil collecting is a largely amateur pursuit. Academics, it would seem, largely ignore the private collections - as in some way tainted. Museums of course, are overloaded with rocks and fossils - they can only hold so many.

Geology is a fascinating science subject

At www.smithsonianmag.com/travel/when-texas-was-bottom-sea/ ... is one of those imponderables. Guadelupe Peak, the highest mountain in Texas, looks across the jagged spine of El Capitan, which looks almost like the prow of a great ship rising out of the ground. The road to El Paso is in the plain below and Guadelupe Peak, and indeed, the Guadelupe Mountain range, are full of fossils. They go way back to when they were under the sea, forming part of a reef system that was some 400 miles in length.

Fountains of the Deep

At http://phys.org/print338021988.html ... hydrogen rich waters have been discovered deep underground in different locations around the world - including Canada, South Africa and Scandinavia. This water has a chemistry similar to that found near deep sea vents. Hence, underground water may actually be feeding the oceans. The paper is in the Dec. 18th issue of Nature and the data is derived from 19 deep mines.

Ice Cores

Some interesting ideas on the ice cores. Are the mainstream dates acceptable because they fit into the uniformitarian model as they appear to rely on oxygen isotopes for dating the cores. An alternative method of dating the cores may have been rejected because the dates did not match the theory. This fascinating debate can be found at

Baker's Hole

Baker's Hole at Ebbsfleet in Kent is an old chalk quarry situated next to a big railway station on HS1 and contains sediments going 250,000 years ago - which include Palaeolithic remains (Neanderthal). Stone tools, mammoth teeth and fossilised bones of deer, bison and lions have already come to light. See http://phys.org/print335608632.html

A boulder that was swallowed by a lot of clay

At http://phys.org/print335727974.html ... builders in Everett, Washington State, came across the boulder 30 feet beneath the ground - a rather large pebble

the big land slip in the big country

At http://phys.org/print335611854.html ... and sent in by Gary, the same story is at www.dailymail.co.uk/sciencetech/article-2841829/The-largest-landslide-Earth Researchers-reveal-ground-really-did-Utah-21-million-years-ago-shifting 55-MILES-minutes-killing-path.html ... which has more pictures and a map that refuses to load on to this page. This is a geological story that has changed over the years, variously dated 21 or 22 million years ago and previously thought to be a series of land slips that took place over a long period of time.

Oceanic Plates

At http://phys.org/print335167915.html ... it is said that the continental margins on either side of the Atlantic Ocean are thinner than expected and a paper in the journal Nature offers a reason why this may be so. You may have guessed - the explanation fits comfortably into the consensus Plate Tectonics theory. We are informed the bottom layers of continental shelves are being pulled off by subducting oceanic plates. Apparently, the claim is that there are two small subduction areas, one around Gibraltar and the other on the opposite side of the Atlantic, in S America.

Vanuatu

The volcanic island of Vanuatu in New Caledonia is prone to earthquakes and is positioned near an ocean trench - or fault. Scientists and geologists from New Zealand's James Cook university have discovered Vanuatu is not all it seems. Apparently, the volcanism is laid down on top of an ancient fragment of the Australian continent - which is situated 2200km away. Similar pieces of stranded continent exist in other parts of the world - in the Indian Ocean for instance, and Iceland (and various other locations in the Atlantic and other oceans).
