Fossils in Amber

We all know about insects in amber, preserved as fossils and highly prized by our ancestors. The trade in Baltic amber during the past is well catalogued in archaeological studies. The entombed insects of Baltic amber go back to the Eocene. Amber comes from the resin of trees - but the species of tree has not been identified. What you might not know is that fossilised tree resin has been found all over the world and from different epochs in time - see the Deposits Magazine (Southwold in Suffolk) issue 26 (2011).

Smooth faced rocks and electric fields that turn liquids into solids

Two very interesting stories, one is geological and the other, physics. At - it seems that rocks and boulders rubbing against each other can produce smoothing - something normally attributed only to water action. Bumping and grinding in response to the earth shaking in its bowels creates a smooth surface over time - just as rocks and boulders being jostled by water, in rivers, on coasts (by the tides) and during flash floods etc. In this instance the process was visibly taking place - in a dry desert at high altitude.

A lushly Green Land

Greenland was once a tropical country - near the equator - or was it? Scientists from the Smithsonian have the evidence from rocks they have collected (see ). During the Cretaceous era Greenland was covered in a tropical rainforest and the same situation has been noted in NE America and Spitzbergen.

Feathers in amber

At ... University of Alberta scientists have found feathers preserved in amber, from the Late Cretaceous era (towards the end of the dinosaur age). No mention of sudden apocalyps. It is thought the feathers, blown in the wind perhaps, landed in tree resin which preserved them - but how long did it take for the resin to harden? Fossilised feathers have also been found preserved in sedimentary rocks.

Up for Grabs ... flint. What is it and how did it get here

In response to Gary Gilligan's ideas about flint (see his web site, and the significance of the study at ... a rather interesting paper on the role of flint as an attribute of the Gods, I thought I might look up the orthodox view of how it was made. This perforce has to be from a UK perspective - not from Egypt.

Huge lava plume

A paper in Earth and Planetary Science Letters ( see has found evidence of a lava plume on now widely distributed pieces of the earth's crust that at the time are thought to date from when all of them were joined together in what is geologically known as Gondwanaland (a combination of South America, Africa, India, Antarctica and Australia). The lava plume, it is suggested, broke apart Gondwanaland - but what event might have caused an outwelling of lava on such a scale? 

Geochronology, smokers, and dinosaurs that lived in darkness (?)

See - scientists at the University of York have developed a new dating technology for geological deposits of the Quaternary Period (the last 3 million years). Its basically a refinement of an older process, the use of amino acids in geochronology that measure the breakdown of proteins in fossil snails. Snails are commonly found at archaeological sites in Britain and in geological contexts.

Velikovsky, Hibben, and the Alaska 'muck' deposits

Velikovsky in Earth in Upheaval, at the very beginning of the book and therefore in order to draw the reader's attention, chose to quote Hibben on the Alaska muck deposits (he also quotes Rainey). Hibben was specific that the muck had a catastrophic origin - by tsunami or whatever. Hibben's article in American Antiquity, 1943 (volume 8:3) has over the last 60 years or so come under a lot of fire by detractors - but has enjoyed a consistent vogue amongst catastrophists of various persuasions, and is quoted endlessly by creationists resistant to uniformitarianism.

Iron meteorite, 25 tons

At there is news of a huge iron meteorite in the remote Altai mountains, on July 16th (2011). It has an estimated mass of 25 tones and is partly buried beneath a large slab of granite. This means both rocks have probably moved - and as it lies in a glacial valley the culprit is obvious. The question is how old is it, is it part of a larger cosmic object, and where might the other bits lie?

Volcanoes on the Moon

At (and many other blogs around the world) there is a report on the discovery of a volcano hotspot on the far side of the Moon (source being the journal Nature Geoscience) which came about as a result of images taken by NASAs Lunar Reconnaissance Orbiter. The volcanic activity took place millions of years ago - 800 million years ago according to ABC. This is of course an estimate basied on consensus thinking of the Moon's geology and origin.
