Volcanic Fingerprints

Each volcanic eruption gives birth to a unique signature in the composition of the ash and in the glass shards that lodge within soil. Even eruptions from the same volcano have different chemical elements, even down to the shape of the shards. A volcano in Alaska that blew in the 9th century AD has a distinctly high chlorine content and this has helped identify its fingerprint across Europe and northern N America - see http://news.yahoo.com/alaska-volcano-blanketed-europe-ash-1-200-years-21.... The research was done at Queens University Belfash.

Calendars and Sea Levels

Yes, back to another post at http://malagabay.wordpress.com/2014/09/04/catastrophic-chronology/ ... which on this occasion takes a look at Illig, Niemitz, and Hunnivari, who have each produced a different version of an AD revision to that of Gunnar Heinsohn. I'm not sure to what extent the arguments are valid but here we go - starting with Zoltan Hunnivari, who was unable to find a suitable eclipse to fit the prodigy seen on the death of Augustus Caesar in AD14. This supposes that such a prodigy did occur and even if it did that it was an eclipse (or rather an annular eclipse).

Ice cores, tree rings, radiocarbon ... in the News

Doug Keenan refers Bob Porter to an article in the Journal of Geophysics Research 117 (2012), 'Holocene tephras highlight complexity of volcanic signals in Greenland ice cores' at NewChronology [at] yahoogroups [dot] com

Outliers

At http://malagabay.wordpress.com/2014/09/02/catastrophic-dendrochronology/ ... Tim Cullen introduces the concept of catastrophic outliers in dendro constructs that are artefacts of the smoothing process within calibration of tree rings and C14. It is a remarkable insight into what may or may not be what happened during the construction of the modern dating system so faithfully relied upon by archaeologists, historians, and various others - including anthropologists (in the previous post).

Bristlecone pines and Time

At http://malagabay.wordpress.com/2014/08/29/dendrochronology-the-mad-carbo... .. Tim Cullen gives an opinion on the process involved where the C14 model was wedded to the bristlecone pine dendrochronology, an odd sort of marraige of convenience in that C14 was rocking after revelations that dates produced by the methodology not as reliable as claimed - and did not meet the requirements of the orthodox Egyptology. It is now well known that there have been a series of plateaus in C14 that mess up the reliability of the methodology at those points in time.

Mankind in Amnesia

The headline to this was decided because at the end of the piece he has a picture of Velikovsky's book jacket, Mankind in Amnesia. Andrew Fitts, a recently joined member of the society, is particularly interested in this aspect of Velikovsky's work - which we will all find out about in the course of time. The link is again to a posting by Tim Cullen at http://malagabay.wordpress.com/2014/08/18/lacunar-amnesia-in-academia/ ... and is a lovely post that will resonate with Velikovskians, whatever their favoured subject.

Gaps in tree rings sequences

Tim Cullen appears to continue to be impressed by Gunnar Heinsohn's articles at www.q-mag.org (and another one has been posted over the last couple of days). Hence, in this look at the dendrochronology process he is looking for the possibility of an error in the region of 700 years of time being taken out of the first millennium AD. Therefore, he has an agenda. I'm not knocking it - just saying. What he has discovered is that there are two gaps in the sequences - one in the first millennium BC (at the point of the C14 curve) and the other in the first millennium AD.

carbon 14 methodology and its weaknesses

Over at http://malagabay.wordpress.com/2014/05/31/carbon-14-seeing-the-light/ ... Tim Cullen continues his quest to disect carbon 14 methodology - and where its weaknesses might lie. It has continued through a succession of posts and all are entertaining as well as informative. How on earth did this methodology usurp the older dating methods - and it can only be that they were even more unreliable. Cullen claims Willard Libby skewed the data and fudged the core analysis that two atoms of C14 are formed every second for each square centimetre of the surface of the Earth.

Radio Carbon Dating and Dendrochronology

Tim Cullen continues with part two of his critique of C14 dating - go to http://malagabay.wordpress.com/2014/05/16/carbon-14-libbys-ring/ ... which is something of an eye opener in some respects and is mainly a history of the method and how it became embedded in the mainstream as a means of upholding consensus dates and the like.

Dating a cave system in the Yucatan

At www.eurekalert.org/pub_releases/2014-05/ps-dad_1051214.php ... this short piece discloses how a skeleton found in a cave, now 130 feet below sea level, was dated to the Late Pleistocene period. The sea level rise curve was used in order to get back to the desired period, a curve that is based on an assumption sea level rise was a constant process over many thousands of years (following the end of the Ice Age and the melting of a huge ice sheet).
