Did a burning oil spill wipe out the dinosaurs?

New research suggests the Chicxulub asteroid impact threw up billions of tons of oil soot that blocked out the sun for a decade.
The research paper is reviewed and put in context by Nick Longrich, University of Bath. I don't think he was responsible for choosing the imaginative illustration shown above - neither was I! You can find his article HERE.

You will be aware that Elizabeth Devon has moved on - she deserves our thanks for starting and maintaining this blog. It provides a platform for the amateur and professional geological communities to talk among themselves and to each other. I hope to continue her good work.

I am Graeme Churchard, a member of WEGA and now administrator of this blog. My email address is graeme@churchard.com and I would be very pleased for any and all feedback from you. And if you have news of current geological events in the West Country, let me know and it will appear here. And items of general geological interest are always welcome.

I have just finished transferring Elizabeth's list of email addresses to my system. I hope I did it without mistakes, but let me know if I got your name wrong. My system doesn't like an email address with two names attached, so if you get an email with a strange mixture of names, let me know what is your preferred name for emails from this blog.

October - Field Geology in mid Wales

Lifelong Learning 4 day course:-
Field Geology in Mid Wales: volcanoes, tropical reefs and copper ores 
Two weekends in October: 15th, 16th, 22nd, 23rd
10.00 am – 5.00 pm each day. 
The hill country near Builth Wells and Kington contains some of Britain’s oldest rocks, from late Precambrian to Silurian ages. We visit nationally-renowned locations, including active quarries where the geology is clearly visible, and where the collecting of rock types, minerals and fossils is unrestricted.
No prior knowledge of the area or geology is assumed.

Please note you will need to make your own travel and accommodation arrangements, with meeting times and places to be confirmed.  
The course is organised through Cardiff University. It carries assessment, which is very difficult to fail! Attendees usually find assessment on these courses useful for consolidating what they have learned.
Tuition fee is £160.00  (concessionary fee available £128.00).
Enrolments can be made by ‘phoning 029  2087  0000  or see website.

July 7th - Environmental Impact of a degassing volcano, Masaya, Nicaragua

Environmental Impact of a degassing volcano, Masaya, Nicaragua
Professor Hazel Rymer, The Open University

Thursday July 7th, 7.30 p.m.
Our primary goal is a better understanding of the environmental and ecological hazards posed by gas emissions at persistently active volcanoes. Armed with this understanding, our second goal is to develop strategies to mitigate the environmental and ecological risk at these sites.
