Origin of Water

Further to the post www.sis-group.org.uk/news/hydrogen-and-water.htm ... on November 11th we have an article in an Australian source on the subject - see https://cosmosmagazine.com/geoscience/geophysicists-propose-new-theory-t... ... which actually is the same story but in a more coherent form. They refer to a paper in the Journal of Geophysical Research:Planets by Steven Desch from Arizone State University (which is where this subject started out but was sidetracked by other theories, water from asteroids).

Hydrogen and Water

At https://www.eurekalert.org/pub_releases/2018-11/asu-agd110618.php ... geoscientists have found that Earth contains within itself six or seven global oceans worth of hydrogen - in addition to all the water in the oceans. Where did that water come from? New research, which may or may not be controversial, from Arizona State University, claims they have found the answer. They say our planet contains much more hydrogen, a proxy for water, than scientists previously imagined. Now it is being asked - where did all that hydrogen come from?

Raising the Land

At https://phys.org/print460738798.html ... the 2016 Chile earthquake caused the land to rise on two islands off the coast. A bleached fringe of dead marine algae, strung along the beach, represents the old coastline - as can be seen in the image below. This is what is known as a fault slip.

 

British Plate Movements

At https://eurekalert.org/pub_releases/2018-09/uop-gra091218.php ... the British mainland, we are told, was formed by the collisions of three land masses. It has long been thought that most of Scotland was not always part of the British Isles - but now geologists have been investigating the SW of England and have come to the conclusion there was a third piece of the puzzle. This concerns all of Cornwall and a large dollop of Devon.  They say this piece of real estate was once part of France (pointing at similar geology in Brittany) and separate from the rest of England and Wales.

Origins of Salt

Robert Maximus has a thread on the thunderbolts forum on catastrophist geology and at one point the discussion moves to the origin of rock salt - and Robert quotes from https://creation.com/magmatic-origin-salt-deposits .. large formations of rock salt are found on all the continents. Oil and gas often coincide with salt deposits - in the North Sea basin for example. Salt deposits are often described as 'evaporites' (left behind by a former sea).

Horses and Dragonflies

At https://phys.org/print454252017.html ... a fossil horse foal has been uncovered in Yukatia in Russia - perfectly preserved in the permafrost. It still has its skin, hair and tail/ It is estimated to have died between 30 and 40,000 years ago.

   

Yosemite Granites

This comes from www.sciencedaily.com/releases/2018/06/180627160430.htm ... Yosemite granite tells a different story about Earth's geological history, is the blurb. What do they mean? Granites in Yosemite National Park contain minerals that crystalised at a much lower temperature than previously thought possible. Apparently, this upends our understanding of how granites form - which seems very important (but is it?). Granites are igneous rocks - mainly quartz and feldspar. They are the link between igneous processes within the Earth and volcanic rocks that solidified at the surface.

Super Highway

In Science Reports (August 2018) we have dinosaur tracks found in Alaska - see https://phys.org/print452768549.html ... and now it is proposed Alaska was the gateway to the New World for the dinosaurs (and now where have we heard something like that). This is an interesting idea because if it is true it may indicate the Earth's topography was quite different in the dinosaur era. If Alaska was joined at the hip to Siberia and the Atlantic was much narrower than it is now (as Plate Tectonics might dictate)  what might that imply? A smaller Earth.

Krakatau Big Bang

At https://tallbloke.wordpress.com/2018/08/04/earthquakes-can-systematicall... ... a big earth quake can generate after shocks (or a succession of earthquakes in the same general location) - but it can also generate earthquakes on the opposite of the planet.
