At http://malagabay.wordpress.com/2013/11/04/liesegang-rings-5-geological-q... ... Tin Cullen gets more and more interesting as he probes down through the uniformitarian minefield of geology. Silicates, according to the consensus view of the late 19th/ early 20th centuries, were thought to have had a gelatinous stage before ripening to become agates, and this involved liesegang rings.
There is another paper out this month that may be saying more than it actually admits in the written form - go to www.sciencedaily.com/releases/2013/10/131014221537.html where the published article is commented on (from Quaternary Science Reviews). The authors have found evidence that the great rivers of East Asia control dust and sand transportation and deposition.
The September issue of NCGT Journal is now available to download and print out in pdf at www.ncgt.org/newsletter.php (or www.ncgt.org/nws/909848777ac2dc52479540e3efc31add.pdf) ... William Thompson forwarded the link where there are some interesting letters as well as articles, with geophysics the main focus. Basically, it is a forum for those geologists and geophysicists who aren't in love with Plate Tectonics, the likes of David Pratt for example.
At http://phys.org/print300352509.html ... a core sample from New Jersey geology, in a region once beneath the sea (55 million years ago) has clay bands around 2cm thick that appear to have been laid down rhythmically, or cyclic. As such, they were akin to tree rings, providing an annual pulse, a yearly amount laid down as strata. I've heard similar wave patterns in sediments described as Milankovitch periods but annual changes preserved in the geological record doesn't appear to comply with uniformitarian geochronological parameters.
This story is at several places with a different emphasis at some of them. At http://phys.org/print300385973.html ... there was an abrupt climate shift in the Florida Everglades at 800BC. Obviously, it impacted a larger region than just southern Florida - but this is where the field research took place. A prominent semi permanent high pressure weather pattern commonly known as the Bermuda High dominated the weather. As a result of the shift tropical storms that routinely struck Florida moved to the south - the Gulf of Mexico.
This story is at http://phys.org/print299837731.html ... this has been found on Ngaanyat jarra tribal territory by the Geological Survey of Western Australia and comprises 450 cubit km of formerly molten magma from a single eruption. However, they claim it was active in access of 30 million years - which isn't quite the same thing.
Thousands of dinosaur tracks, of different size and shape, have been found along the rocky shore of the Yukon River - see http://westerndigs.org/thousands-of-dinosaur-tracks-discovered-along-ala... These are not imprints, in soft mud that solidified, but casts - fossils of sand and other sediments that washed into fresh dinosaur footprints and were left behind when the outer rock eroded away. They found dinosaur footprints by the score on literally every outcrop they paused at. They were so abundant we could collect 50 specimens in as little as ten minutes.
Dynamical processes in nature take place over a large range of time scales. In addition, subatomic particles decay over a time scale of billionths of a second. Some geological processes take millions of years. Physical science is full of examples of processes that play out over long periods - and short periods of frequency, too.
This story was in 'Down to Earth' 84, August 2013, a geological magazine that organises a lot of field trips, in Europe and further afield, and has pieces by local geologists in various parts of the UK. There have been lots of erratic boulders found along the south coast between Portsmouth and Brighton. They include granites, syenites, schists, slates, vein quartz, quartzites, sandstones, and limestones, and some of them can weigh up to ten tonnes.
