The Sudbury Anthraxolite Report, by Robert A. Szep

The origin of carbonaceous matter in the form of finely disseminated particles and in the form of anthraxolite dikes in the Sudbury impact structure has been debated for some time past. Endogenetic processes as well as the formation in the impact cratering process or the impactor to be the source have been suggested, and carbonaceous material in meteorites and fullerenes in Sudbury rocks have stimulated the discussion.

We also mention the occurrence of peculiar carbonaceous material in the mid-Tertiary Azuara - Rubielos de la Cérida multiple impact event (see the article by Ernstson et al.:  Unusual melt rocks from meteorite impact [http://www.impact-structures.com/article/article_4.html]), in the strewn field of the Holocene Chiemgau impact event (Rösler, W., Hoffmann, V., Raeymaekers, B., Schryvers, D., Popp, J. (2005): Diamonds in carbon spherules - evidence for a cosmic impact?. Meteoritics and Planetary Science, 40, p. A129; also see: The Holocene Tüttensee meteorite impact crater in southeast Germany http://www.chiemgau-impact.com/artikel2.pdf), and in the heavily controversial 13,000 years BP comet impact, see http://www.nsf.gov/discoveries/disc_summ.jsp?cntn_id=109768.

Robert A. Szep is well known among meteorite and impact researchers and collectors as an impact-experienced field collector of impactites. He created, produced and authored The Third Millennium Meteorite Calendars, published in 2000 and 2003 and has written articles such as "The Sudbury Star Wound" and "When Big Things Strike Earth - on the topics of meteorites and impact structures".

Additionally, “Zep” has been interviewed on local and nation-wide TV and featured & quoted in local & national newspaper articles, also on the subjects of meteorites and craters, on a number of occasions over the past decade, all in order to increase interest & awareness of these things among the general public. His first-hand report, based primarily on field observations and subsequent study and testing of sampled material, is written in a manner that makes what the average person might consider a mundane topic, interesting. 

As a regular visitor to this website, Robert asked us if we would be interested in placing his Anthraxolite Report on our website, and, of course, we are fond to do so, and we also mention his disposition to provide researchers and collectors with this peculiar material.

Readers being interested in the Sudbury carbonaceous material are referred also to an abstract article: RAMAN STUDY OF CARBONACEOUS MATTER AND ANTHRAXOLITE IN ROCKS FROM THE SUDBURY, ONTARIO, IMPACT STRUCTURE by Dieter Heymann and Burkhard Dressler, see http://www.lpi.usra.edu/meetings/lpsc97/pdf/1268.PDF.

Ancient Crashes - Holocene impacts

Most astronomers are convinced that the Earth has experienced not any large comet or asteroid impact in Holocene times (the last 10,000 years). One of their key arguments is that statistics (!) speaks against such recent events. They may be wrong because the evidence of such impacts is fairly strong, as has especially been stated by the two-year-old Holocene Impact Working Group.

A recent article in The New York Times sheds some light on this controversy, and an article and a book to appear (see below) will with certainty fuel the discussion. On this background we suggest to adapt statistics to given evidence.

Ancient Crash, Epic wave - Did an Asteroid Impact cause an Ancient Tsunami?

Does the myth of Phaethon reflect an impact? – Revising the fall of Phaethon and considering a possible relation to the Chiemgau Impact  (by M. & B. Rappenglück)

Abstract. - In Greek mythology there exists one story that has repeatedly been interpreted to describe the fall of a celestial body: the story of Phaethon, who undertakes a disastrous drive with the sun-chariot of his father Helios. First, the article presents the arguments given by ancient authors for interpreting this story as the reflection of a natural phenomenon. Then details given in the old descriptions of Phaethon’s fall are compared with nowadays knowledge of impact phenomena. Furthermore the texts are examined for clues to the time and the location of the hypothesised impact. These considerations substantiate the suggestion that the myth of Phaethon reflects a concrete strike of a meteorite, the so-called Chiemgau Impact. That impact struck the south-east of Bavaria/Germany at some time during the Celtic period and left an extended crater-strewnfield of about 100 craters. A conspicuous intersection between the tradition of the Phaethon-story and the up to now known time-frame for the Chiemgau Impact gives new clues for dating the Chiemgau Impact to the time between 600 and 428 BC.
