Canyons carved by Climate Change

This climate change malarkey has now migrated to the Pliocene period, and it is said to lie at the root of canyons formed on the Andes Plateau in Peru and Bolivia. Canyons are viewed by uniformitarian geologists as a proxy for uplift and tectonic processes. Here we have one of those interpretation problems caused, it would seem, by the geochronological framework rather than by fact, and the enormous amounts of time postulated as elapsing between one strata of rock and the one above it. An in-house anomaly you might say - like creative accountancy.

Rocks that aren't so old

At http://phys.org/print295079728.html and www.sciencedirect.com/science/article/pii/S0009254113002696 ... iron ore deposits in the Pilbara region of Australia are between 26 and 2 million years of age - much younger than most of the similar geological formations, and this is using uniformitarian methodologies based on decay rates. The iron ore was laid down in the Miocene - iron rich sediments accumulating at the bottom of ancient river channels (over tens of millions of years, they claim).

Ice Ages are not all they are cracked up to be

At http://phys.org/print295101717.html ... mainstream say that Ice Ages and warm interglacials have alternated regularly, almost like clockwork, for millions of years. Earth's climate, the theory alleges, cools roughly every 100,000 years - with vast areas of N America, Europe and Asia buried under very thick ice sheets. At the end of the Ice Age it gets warmer and ice melts - which lasts roughly 10,000 years - before descending into another cooling. In other words, for roughly one tenth of time that has elapsed in the Pleistocene the world is an agreeable place to live.

Loki's Castle

At http://phys.org/print294650860.html ... in 2008 Norwegian scientists discovered Loki's Castle, a field of five active hydrothermal vents on the Mid Atlantic Ridge between Norway and Greenland. IN association with Loki's Castle are rich metal deposits - and a unique biology. In the seas west of Norway there are volcanoes and active earthquake zones, assumed to be part of the process of Plate Tectonics. Hydrothermal vents churn out hot water - at up to 360 degrees Celsius. No wonder climate scientists, and the Met Office people, think global warming is hiding in the oceans.

Geological Oddities

At http://malagabay.wordpress.com/2013/07/21/geology-mind-the-gap/ ... is another amusing post from Tim Cullen with a sarcastic take on geology as it is presented by mainstream academia. In this instance the focus is on stratigraphy - but whether you fall for it or not it is still something to think about as many a true word is said in jest. Min the Gap is a reference to the fact the sedimentary record is incomplete - vastly so. There are gaps - even Charles Darwin told us about those gaps.

Man Made Earthquakes

One of the more recent scare stories circulated by environmentalists as an anti-fracking tactic, is the idea of humans causing earthquakes - a theme of a recent post. In this one the evidence comes from a geological source, at www.usgs.gov/blogs/features/usgs_top_story/man-made-earthquakes/

Melting ice sheets - the Antarctic

This is not climate related, as such, but a geological conumdrum - see www.sciencenews.org/view/generic/id/351788/description/News_in_Brief_Mil... ... this happened in the Pliocene, which in geochronology directly precedes the Pleistocene and as a result of uniformitarianism is duly dated millions of years ago. The evidence of ice melt in Antarctica comes from sea floor sediments 300+km from the continent. The sediment core was rich in algae, a sign the ocean was warm.

Sea Level - problems associated with calculations

At http://malagabay.wordpress.com/2013/07/13/the-inflating-earth-sea-level/ ... Tim Cullen takes a look at sea levels in the context of the Inflating Earth hypothesis. What he says is interesting to all geologists and anyone else that might have faith in the science involved. Local mean sea level is defined on the height of the sea with respect to a land benchmark, averaged over a period of time, long enough that fluctuation caused by waves and tides are smoothed out.

Silica and Sand formation - an alternative view

In a follow up post on July 3rd Tim Cullen expands further on the geological jigsaw puzzle associated with chalk formation - and includes on this occasion the flints found within the chalk - go to http://malagabay.wordpress.com/2013/07/03/the-chalky-cretaceous-2-the-ey...

The Chalky Cretaceous

It's a fact that chalk formed extensive beds in the Cretaceous but nowhere in the world is there evidence of chalk being formed today. Limestone, which is closely related to chalk, being formed also of the shells of marine life, was generally laid down earlier than the chalk. For example, the limestone rocks of the Peak District and the Yorkshire Dales is derived from former coral reef systems when Britain was situated in warmer climes.
