Cretaceous Warming

One feature of geology that seems to have become entrenched in recent years is the idea that during the Cretaceous era global warming was rampant. Initially, this was theorised in order to explain trees growing on Ellesmere Island and other unlikely places where it is dark for almost six months of the year. It also explained the apparent semi tropical habitat that appears to have prevailed in southern Britain, and so on. At ... this is expanded to inlcude palms growing in Canada and lily pads within the Arctic Circle etc.

Plate and Saucer

Plate Tectonics wasn't always accepted without question. There was a time when some geologists were more than a trifle sceptical. A paper published in 1972 illustrates some of the problems inherent within the new theory - go to ... Objections to Continental Drift and PlateTectonics.pdf

Lost river

At ... the fasted flowing of the glaciers on Greenland is actually situated on a lost river - in fact a huge river basin 12km wide and as deep as 1400m in places (all hidden under the ice). The river was in existence prior to glaciation.

More on Surprising Mars

Gary Gilligan has replied to the first post, June 14th, and raised some interesting points about silica, and to the apparent violent history of Mars. The link provided, at ... actually implies that on earth tridymite forms at extremely high temperatures in an explosive paroxysm known as silicic volcanism (and Mount St Helens is cited as an example).

Another Seismic Query

At ... seismic activity is problematic as it doesn't choose to conform to theory. For example, sensors have been installed at fault lines in California in order to monitor EQ activity - especially in the vicinity of the San Andreas fault (widely tipped to shake itself sometime in the near future but apparently stubbornly refusing to co-operate with the sensors). Most of the time fault lines are very quiet and do not pick up any kind of bleep out of the sensors. It is all quiet on the San Andreas fault.

Super Computer Geology

At ... super computer modelling of Plate Tectonics and how it effects the crust and upper Mantle regions, has come up with some answers it is claimed. Old geological events may have actually come to life over and over again and are involved in earthquakes, any kind of seismic phenomena including mountain building, and various other earth processes not fully understood. You can do anything with a super computer it would seem, even iron out the anomalies in Plate Tectonics theory.

Big Holey

At .... we have a piece on that crater that mysteriously appeared in Siberia - triggered, it would seem, by an explosion of some kind. The sky is also said to have glowed. This story goes back to 2013, some months after the Chelyabinsk meteor (and another meteor was ruled out for various reasons.

More on K/T in Antarctic

At ... we learn that during the Cretaceous period Antarctica was covered in rainforest and probably looked something like a virgin New Zealand environment, or some parts of modern South America. It goes on to say that Antarctica was still at the South Pole and there were not ice sheets at the poles as the Cretaceous was a very warm period - due to runaway global warming (according to mainstream geology). Obviously, this was not human induced global warming but the claim is that the climate of the earth was so warm the ice sheets had melted.

Antarctic and the whack

The K/T boundary event (asteroid or comet whack) had a definite impact on the Antarctic according to Research published in Nature Communications (May 2016) analysed 6000 marine fossils that lived between 69 and 65 million years ago (the end of the Cretaceous). These were examined by scientists from the University of Leeds and the British Antarctic Survey on Seymour Island in the West Antarctic peninsular. The collection included snails and clams as well as marine reptiles.


Sediments in the Bay of Naples have been explored and have revealed how the eruption of Vesuvius affected water supply and sewage/drainage systems - see

Interestingly, a similar setback was seen to have occurred in the 5th century AD as a result of natural disasters and invasions of Italy. This led to a decline in maintenance.
