Plates and Dynamite

At http://archaeologynewsnetwork.blogspot.co.uk/2015/01/nannofossils-from-e... ... concerns the origin of the Canary Islands - which are, like the Hawaian islands, located in the middle of a plate rather than at the plate boundary. In 2011 and 2012 there was a lot of volcanic activity off the Canaries which led to the study. The research found sedimentary material which contained small fossils of the Cretaceous Period - which seems to rule out the idea it was dredged out of the mantle (where volcanic magma is thought to originate).

blow-outs and bumps in the nether parts

At http://news.yahoo.com/did-volcano-wipe-neanderthals-144225250.html ... it has been suggested a massive volcano that blew around 40,000 years ago led to the demise of the Neanderthals. Benjamin Black, a geologist at the University of California, has explored the issue and found it wanting. The criticism sounds reasonable. What was not asked is what caused such a big volcanic explosion?

ocean circulation streams

At www.q-mag.org/mega-streams-of-the-atlantic.html ... we have something that I've not seen anywhere else - somebody questioning the idea of the ocean circulation system, or how it actually works. Between Greenland and Norway an enormous mass of water, according to mainstream, plunges down into the deep of the Atlantic, and travels south along the bottom of the ocean, eventually reaching the tropics once again, where it originated as the Gulf Stream, a huge mass of warm water that provides north west Europe with an exotic marine life that has been exploited over centuries.

the uranium cycle

This is an interesting one as uranium isotopes are used to date rocks and float the geochronological time span. The story is at http://phys.org/print340960522.html ... and no doubt some people are inclined to doubt the whole exercise. Never the less it is all part of the Uniformitarian construct and requires understanding by critics and those with just a thirst for general knowledge. Basically, uranium isotopes are used to date the different rocks assigned to the different periods in the geochronology that has been developed over the last couple of hundred years.

Lakes in the Sahara

At http://phys.org/print339925008.html ... we have a fascinating story, rock art that depicts people swimming (a sort of dog paddle) - in one of the dryest parts of the Sahara desert. Whether they are really swimming is a matter of opinion. They could equally be flying - almost floating in the sky.

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
