A funny looking crater on Mars

At www.sciencedaily.com/releases/2010/08/100827082326.htm .... Orcus Patera is a mysterious elliptical depression near the equator of Mars, some 380km by 140km in a NNE - SSW direction. It has a rim that rises up 1800m above the surrounding plain while the floor of the depression is some 400 to 600m below the surrounding landscape. It doesn't fit into any currently accepted pattern - impact or volcanic

... yes, there are nano diamonds at the YD boundary event, preserved in ice on Greenland.

This is a paper by Kurbatov, Mayewski, Steffensen, West, the Kennetts, Bunch, and others which can be downloaded free in full text from http://cosmictusk.com August 31st. Recommended reading. Basically, a small layer of free nanodiamonds in very high abundances implies an unprecedented influx of extraterrestrial material  that occurred over the last glacial episode. From that layer nanodiamonds and hexagonal diamonds (lonsdaleite) of the order of many times grreater than background levels in adjacent younger and older ice.

No nano diamonds at YD boundary ....

Embedded resistance to the YD boundary event is evident in the post at www.sciencedaily.com/releases/2010/08/100830152530.htm (see also www.physorg.com ), a report on a paper published in the August 30th issue of the Proceedings of the National Academy of Science by Tyrone Daulton, Pinter and Scott et al. They say they could find no evidence of nanodiamonds in YD boundary material - and this means the impact hypothesis has lost it's sparkle.

Other Worlds

The Journal of the British Interplanetary Society published a letter in 1986 that has obviously intrigued Paul Gilster for a long while - see his blog at www.centauri-dreams.org and the posting for August 26th 2010). It is all about contact iwth other civilisations - and other worlds. What if advanced civilisations did tend to explore their immediate solar systems, but for various reasons confined themselves only to their neighbours and not to space at large - might this explain why nobody has been in contact with the earth.

Nasca Lines ... and water

At www.andina.com.pe/Ingles/NoticialImprimir.aspx?id=313896 August 27th ... we have a Peruvian account of American research that has previously appeared in book form. The theory was advanced that the Nasca Lines may have a connection with water. Basically, he is saying the geoglyphs may be a sort of map of underground water sources in a harsh and very dry environment - a desert. The pattern of straight lines is located in a small area 37 miles long and just one mile wide.

YD event update

Bill Napier reports that a Canadian radar meteor team has confirmed and modelled the predominance of Comet Enck/progenitor in the Zodiacal Cloud (a catastrophist model). At this moment in time the thesis goes unchallenged in astronomical circles. Nobody has produced a viable objection to date as yet. A meteoroid storm, he asserts, is a plausible scenario. He continues by saying he would like the progenitor to be some 100,000 years of age (in the solar system) which is in line with Fred Whipple. However, David Asher and Duncan Steel see it as somewhat younger.

San Andreas Fault ... tremblors going back 700 years

At http://geology.com/press-release/san-andreas-earthquakes-frequency/ earthquakes have been a regular feature along the San Andreas fault system for a long time and a series of tremblors have been charted over the last 700 years. The September issue of Geology says that large ruptures have occurred on a stretch of the fault 100 miles NW of Los Angeles (where the research took place), at a rate of between 45 and 144 years apart. The last really big quake was in 1857, over 150 years ago.

K/T boundary event - a compromise?

BBC News August 30th ... the K/T boundary event, it seems, involved more than one meteorite, or asteroid strike, according to a new study in the journal Geology by Professor David Jolley at Aberdeen University. The Boltysh Crater in the Ukraine was first reported (in the west) in 2002 and scientists have now examined pollen and spores of fossil plants in the layers of mud that have infilled the crater. They found that immediately after the impact ferns quickly colonised the davastated landscape.

The henge in Herts again

See www.culture24.org/ August 30th ... (subsection, history and heritage - some pictures of the dig). The bank surrounding the ploughed out henge has managed to preserve some deposits in the ditch, by infill, and in the bank itself. These display evidence of burning before deposition suggesting a burnt offering, an apparently universal activity, or a cremation (another phenomenon not unrelated). The henge lies at the head of a shallow valley facing NE.
