[Paul]

Dear Ted,

What is the citation for this study? (Where was it published?)

“Matt - In a study we did several years ago, we 
found one shocked quartz grain per 7000-12000 
grains in various sedimentary rocks and glacial
tillites.”

On 3/24/08 9:51 AM, "mmorgan at mhmeteorites.com" asked:

“really makes me wonder how much shocked 
quartz could be found as "background".”

Yours,

Paul H.
