Geology news

a crack in N America, some Australian volcanoes, and an ancient mountain formation that has disappeared into dust, apart from the roots (a bit like a broken tooth).

At http://phys.org/print332685617.html ... there is apparently a mid continent Rift across the Mid West, some 2000 miles in length, running from Lake Superior south as far as Oklahoma and Alabama. However, it is unseen - as it is now underground. Geologists say it began as a narrow crack in the crust which was subsequently enlarged by the welling up of volcanic rock, and somewhat later, further intrusions of igneous rocks buried the feature.

Bermuda Triangle

We haven't heard a lot from this bit of alarmism for awhile but www.livescience.com/48290-siberian-holes-bermuda-triangle-mystery.html ... where it seems several mysterious craters that have mysteriously appeared in Siberia are being used to explain the hype surrounding the Bermuda Triangle. Explosions of trapped methane gas are thought to account for the Siberian craters - but this should not be thought as a given, but a hypothesis.

Volcanoes on the Moon in the time of the dinosaurs

At www.dailygalaxy.com/my_weblog/2014/10/ ... scroll down to October 14th - where to start we have black holes - do they eject matter or does matter fall into them? This is followed by 'NASA: Moon's volcanoes were active during the Earth's Cretaceous Period (the age of the dinosaurs). This is potentially significant because 'things' were happening on Earth as well as on the Moon, not least the asteroid strike.

Sam Carey

Australian geologist Sam Carey, in the 1930s, explored the continental drift theory of Alfred Wegener, which in those days was regarded as junk science. Carey took the trouble to build a model of a globe on which he could move around the continents as part of Wegener's theory was the single land mass known as Pangaea. He realised the continents would fit together if the Earth was smaller. If it was shrunk enough it all slotted together like a jigsaw puzzle - but it would mean doing away with the ocean basins.

Cracks in the Earth's Surface

At http://terracycles.com/joomla/sections/5-earth/36-expandingearthjune2012 ... in Ethiopian a large crack opened up in the crust of the Earth in just a few days in 2005. At the time geologists became very excited as it was thought this was an embryo rift valley that would end up splitting Africa asunder and give birth to a new sea. That was of course as a result of consensus Plate Tectonics - the mainstream theory on how oceans form from rifts and faults, expanding into mid ocean ridges etc.

Subhasis Sen

Subhasis Sen is the author of 'Decoding the Solar System' (2011), a retired Indian geologist. He has taken an especial interest in the geology of Gondwanaland (the southern half of Pangea) from which he developed an expanding earth theory based on global tectonics. He has used this research into earth geology to take a different approach to solar system geology, a novel approach, or projection.

Mount St Helens and Catastrophism

There is an illuminating article at www.icr.org/article/mount-st-helens-catastrophism/ ... which shows quite clearly that sedimentary geology can be laid down very quickly and this contradicts the consensus gradualist view of geological chronology. However, the difference between ICR and neo-catastrophism is not in how long it takes events to unfold but the overall time scale of earth history. Whereas ICR might like to reduce the latter along the lines of Biblical numbers and therefore over egg the role of the Biblical 'flood' event neo-catastrophism is markedly different.

Expanding Earth versus Plate Tectonics

At http://expansion.geologist-1011.net/ ... the expanding earth theory is discussed from the perspective of a mainstream geologist. He begins by noting the expanding earth theory relies heavily on the assumption that subduction does not occur. What he should also have acknowledged is that Plate Tectonics relies heavily on the assumption that subduction occurs - and is not a figment of modelling. This is a different way of making the same point.

Volcanic Sea Mounts

At http://wattsupwiththat.com/2014/10/02/one-wonders-how-many-of-these-newl... ... scientists have created a map of the world's sea floor using satellite data. Thousands of previously uncharted mountains can be seen rising from the sea bed (known collectively as sea mounts). The info comes from a paper in the journal Science (October 2014) and the idea is to provide clues to investigate the consensus theory of ocean spreading - or Plate Tectonics.

Utah, sand dunes and marbles

  At www.livescience.com/39117-navajo-sandstone-dunes-jurassic-earthquake.html ... Utah has some spectacular geology - not least the remarkable sandstone formation above, found in the Zion National Park. These are cliffs of sand and are thought to have originated as sand dunes a very long time ago - in the era of the dinosaurs (the Jurassic).
