Rutland Earth Quake

For more information on the recent Rutland earthquake go to www.telegraph.co.uk/earth/10774635/Second-earthquake-strikes-Rutland.html and www.telegraph.co.uk/news/uknews/10652099/Earthquakes-in-Britain-a-histor... ... and we may note Rutland abuts the Charnwood Forest area of Leicestershire, scene of not only many earthquakes but lots of light phenomena (as a result of seismic disturbance).

La Brea tar pit fossils

At www.sciencenews.org/article/la-brea-tar-pits-yield-exquisite-ice-age-bees ... the image below (at the same link) is of the pupae of a bee (comparing a real life version with the fossilised one). The species still lives in the modern world - but the fossil pupae dates from 35,000 to 40,000 years ago. The presence of bees in the tar pit suggests nearby woodland and river

banks with pollen rich wild flowers or blossom in a fairly cool and moiste climate.

Plate Tectonics and the Oceans

Another interesting article in the March issue of the NCGT Journal (see www.ncgt.org/newsletter.php page 56-60. It is on the origin of oceans and how they don't conform to the idea of new oceans by the separation of the continents. The age of young oceanic crust is defined from Jurassic to Holocene in accordance with the magnetic stripes found on the sea bed. Young oceans are said by mainstream to originate due to the stretching of continental crust (in association with subduction and rifting).

More on the Johnson paper ...

At  www.ncgt.org/newsletter.php ... March issue page 16-37. Johnson describes various theories on the magnetosphere and it inter-action with the solar wind. However, he favours mountain building and uplift being aided by 'super' CMEs, the really big ones that nobody has yet experienced - in the modern world. This is perhaps a drawback but he goes on to claim massive electric discharge currents could activate uplift (augmenting the conventional models of the process). The key here is identifying when mountain building activity took place - the peaks.

Solar eruptions and tectonic uplift

Bob Johnson, at www.ncgt.org/newsletter.php ... comes up with a list of issues. Click on the March issue at the top and a pdf of the whole journal will come up. Scroll down to page 16 for the article - or click on print and when the box comes up alter the page numbers to be printed out to 16-37 and you will get a copy of the whole article with notes. It's a lengthy read and best sat in your armchair with a cup of tea or coffee. Bob Johnson has spoken at past EU conferences and on one occasion at an SIS meeting.

Fossils of the Cambrian

Gary Gilligan sent in a link to a BBC programme, Fossil Wonderlands: Nature's Hidden Treasures, at www.bbc.co.uk/iplayer/episode/b03xsfrq/fossil-wonderlands-natures-hidden... ... which provides confirmation organisms can be buried alive very quickly, and fossilising over the course of time. In this episode it is the Cambrian that is discussed - and Richard Fortey, author of a number of books on geology, appears to be at the helm. Well worth a viewing if you missed the television programme.

Watery innards of the Earth

Tim Cullen has an interesting post at http://malagabay.wordpress.com/2014/03/24/the-eye-of-nebraska/ ... and it's all about water welling up from deep inside the Earth - or that is what it leads up to in a gentle sort of way.

Oceans in the Earth

The key word here is 'in' the Earth - or underground. At http://archaeologynewsnetwork.blogspot.co.uk/2014/03/rare-mineral-points... ... which came about after the discovery of a water rich gem stone. The rough brown diamond has been naturally sculptured to its unusual shape by corrosive mantle fluids during transport to the surface - or that is what is envisaged. The mineral is known as ringwoodite and was found in Brazil.

Old Crusty is more crusty than crusty consensus

The Online journal Nature Geoscience reports on the discovery of the mineral zircon at Jack Hill, 800km from Perth in Australia. The grains of zircon were found in old sandstone and they are said to be more than 4 billion years of age. This indicates the earth's crust formed within 160 million years of the creation of the Earth - which might cause some problems to Plate Tectonics theory. Does new ocean bottom form and replace old crustal material?

Limestone

This is an interesting observation by Peter Mungo Jupp at www.thunderbolts.info/wp/2014/03/05/the-jurassic-coast-a-transmutation-e... ... as in the uniformitarian model limestone is formed slowly, over long periods of time. Limestone rock contains all sorts of fossils - and it is recognised some limestones are actually relic coral reefs. If so this must imply a rapid process - how would you get a fossil reef to fossilise over a long period of time?
