Utah dinosaur pit

at www.smithsonian.com/science-nature/what-killed-dinosaurs-utahs-giant-jur... ... dinosaur boneyards are an interesting aspect of the geological record. One such can be found in a Utah quarry that is roughly an hour's drive from the small town of Price.

is subduction real

Earthquake research came up with subduction to account for tectonic activity in some regions of the planet. However, it very quickly became a boon for the developing Plate Tectonics Theory (in the mid 20th century). It appeared to make sense, allied to the idea of sea floor spreading (an adaptation of continental drift). In spite of the beauty of the match there has always been problems - from the first hatchings of Plate Tectonics. Mainstream tended to ignore the mismatches, and the anomalies, thinking it was just a lack of data.

Messel

  I was watching a BBC television programme the other day on the Messel shale formation. It was fronted by the agreeable Richard Fortey - who was the face in the camera.

ice cores, sea floors, the age of the Earth

At www.icr.org/article/8130 (part one), 8181 (part two) and 8503 (part three) we are told that ice cores must be wrong as the Noachian Flood took place around 4500 years ago - and the ice sheets on Greenland and Antarctica must have formed within that time scale. This is a case of mental gymnastics, even more breathtaking than Gunnar Heinsohn's audacious trunscation of historical records and archaeology.

Lake Chad

At www.sciencedaily.com/releases/2015/06/150629162542.htm ... researchers using satellite images of the ancient shores of Lake Chad as well as studying sediments from the lake to calculate its age have come up with some unexpected results. It was subject to rapid change - turning from a huge lake much bigger than the modern counterpart, over a short period of time. Most of what was a lake is now a region of sand dunes, rocks and dust.

The Stratigraphic Record

Derek Ager's book, 'The Nature of the Stratigraphic Record' (Halstead Press:1973) is a geological gem. It is written by somebody who has been described as a neo-catastrophist. Unfortunately, unlike astronomy, in geology a neo-catastrophist is a bit of a wet fish, a uniformitarian who is prepared to accept that natural disasters such as mega earthquakes and big volcanoes may have occurred. The idea that catastrophes with a cosmic dimension have also occurred is not an area they are prepared to delve into - too deeply.

stretch marks

TimCullen is no respecter of settled science and the big wigs that pontificate - and the academics that prevaricate (but some of his alternative views are quite startling) - for example at https://malagabay.wordpress.com/2015/06/17/palaeomagnetism-logic-reversals/ ... he is his usual irascible self when he says, 'the scientific literature is littered with hypothetical magnetic poles, hypothetical geomagnetic poles, hypothetical geodynamics, hypothetical magnetic reversals and very little of scientific substance.

uplifting times

The sheer power of geological forces is displayed in the picture below, an area of land that was dredged up above sea level during an earthquake in 2010 on an island off Chile

Juneau

Alaska's glaciers are favoured by the CAGW hype industry, in particular the Juneau ice field which contains 32 of them. A claim was made recently that the melting of these glaciers would add a catastrophic amount of water to the oceans - and we were in danger of drowning (or something like that). However, not all of them have been melting - one at least is actually growing, the Taku glacier. However, the Mendenhall glacier has shrunk and trees have been revealed that have been frozen under ice for some 2000 years (roughly).

Under the Ice

At http://geology.com/articles/arctic-ocean-features/ ...

   a picture of the Arctic Ocean sea floor showing basins and ridges etc. How would it have looked when sea levels differed during the last Ice Age - and the Bering Straits were dry land. How much else of the area was above sea level?
