[meteorite-list] Possible Middle Cambrian Impact Megabreccia, Queensland, Australia?

[Paul H.]

Dear friends,

There is a PhD dissertation, which is accessible online
as PDF files that describes a Middle Cambrian megabreccia
in the Lawn Hill region, Australia. It is

Feltrin, L., 2006, Probabilistic and deterministic models of 
Pb-Zn mineralisation and post-mineralisation megabreccia, 
in the Lawn Hill region, Australia. unpublished PhD. 
dissertation, James Cook University, Australia.

It can be downloaded from http://eprints.jcu.edu.au/1614/.

Chapter 7, “Catastrophic mass failure of a Middle Cambrian 
platform margin, the Lawn Hill Megabreccia, Queensland, 
Australia,” of this dissertation can be downloaded from
http://eprints.jcu.edu.au/1614/7/07chapter6.pdf .

Although the author does not favor an impact origin for
this megabreccia, he cannot fully ruled such an origin 
for the Lawn Hill Megabreccia of Queensland, Australia.

Best wishes,

Paul H.
