lunar time and solar time

Another letter is by Giovanni Gregori in support of his earthquake prediction methodology that he is developing. He used the Kolvankar analysis of 5000 earthquakes (2011). However, critics appear to have misunderstood what Kolvankar was saying. He said earthquakes tend to happen at two time internals, one close to 6am and the other, 6pm (local lunar time). Lunar local time, Gregori insists, differs from local (solar) time and the differences vary from site location to site location. Lunar local time is the crucial point in forecasting earthquakes he says.

dinosaur demise

The letters pages of NCGT journal are always interesting. In the September issue (2015) ... Peter James, geologist, has a pop at the current mainstream idea that the dinosaurs were wiped out by an asteroid strike, written a touch tongue in cheek but offering up some criticism of a Catastrophist theory that is now embedded in consensus science. He offers up an alternative catastrophist scenario.

NCTG journal September

The NCGT journal, September 2015, has some interesting articles - go to ... on earthquakes and a connection with solar storms. We have solar polar field magnetism prior to earthquakes, geomagnetic variations prior to earthquakes, outgoing longwave radiation prior to earthquakes, space weather prior to earthquakes, as well as anomalies in jet stream behaviour prior to earthquakes.

English Channel

At ... what made the 22 mile gap between Dover and Calais?

  There are geological faults along the line of the Channel and they are thought to be several million years of age. They mark where part of the crust has slipped - see above.

Deccan Traps

The Deccan Traps, a vast lava outflow, are located east of Mumbai (formerly Bombay), and here we have a bit of putting one and one together and making two - go to

Weaubleau Eggs

Weaubleau eggs are rocky balls, read concretions of rock found in western Missouri. See for example (8th July 2013) (scroll down to that date)

  At the link these rock eggs are compared to more recent impact sites in Spain. The process, they say, is similar to the formation of monomictic impact breccias with rounded clasts. However, the Missouri rock balls are extremely old, it is thought - 330 million years ago.

a core issue

At ... we learn that Earth's core contains more oxygen than previously allowed. Geologist Rick Ryerson and colleagues modeled geophysical and geochemical signatures they thought were involved in the formation of the Earth, accreting material that was more oxydised than the present day mantle material (on the basis that the material accreted would be similar to that of asteroids and planetesimals. The new model differs from the old model - but it is still a model. The research is published in September's PNAS (2015).

big holes in Yamal


At ... we have giant holes created when pingos erupted after filling with gas. The craters are found on the Yamal peninsular in northern Russia and indications are that not all of them were formed in the same way. They were first noticed last year and a variety of explanations have been offered. One if over 60m deep

Arctic sea bed

At ... Durham University has updated a map of the Arctic sea bed which depicts the marine resources that have been discovered in recent years, all part of active collaboration between Russia, Canada, Denmark, Norway and the US. See image below

mantle plume blues

At ... German scientists are questioning another consensus theory, and another important piece of geological thinking. It seems the break up of the continents began around 130 million years ago. Africa and South America began to divide from each other and the mechanism is thought to have involved enormous masses of magma ascending from the deep mantle, rising to a high level of the mantle before the hot mantle plumereached the continental lithosphere, eventually leading to the split.
