dinosaurs Utah

Palaeontologists have discovered a cliff side in Utah full of dinosaur fossils from the Triassic. Preliminary findings were presented at a conference in Dallas in October (2015) - see http://phys.org/print364231424.html

loess (2)

At the recent study group meeting in Willesden we discussed Ellsworth Huntington's research in central Asia and his book, 'The Pulse of Asia' - from the early 20th century. He claimed that wet and arid periods can be seen in the rise and fall of the levels of the Caspian and Aral seas, going back to the Greek era in the first millennium BC (where various authors with known dates and lives wrote contradictory accounts of the lake levels.

loess

Scientists have been looking at sediments formed by the Yellow River in China and it seems the river eroded and incised the Tibetan plateau over millions of years and in the process created the wind blown dust that is thought to form the Chinese loess formations - see http://phys.org/print363580304.html

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) www.ncgt.org/newsletter.php ... 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 www.ncgt.org/newsletter.php ... 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 www.theotherside.co.uk/tm-heritage/background/channelform.htm ... 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 http://phys.org/print362919360.html

Weaubleau Eggs

Weaubleau eggs are rocky balls, read concretions of rock found in western Missouri. See for example www.impact-structures.com (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 http://phys.org/print362144022.html ... 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).
