Bernd kindly mulled over Jeff's clarification for the Wlotzka weathering  
scale:

Hola, would terrestrial carbonate formation be a good metric?  depth  and 
magnitude of the gradient of terrestrial carbonates from exposed  surface to the 
interior?  One problem I could see in standardizing this  would be that 
different environments on earth will yield different types of  weathering, so the 
scale might not generalize too easily. Even the Wlotzska  scale only measures 
the parameters Jeff mentioned, so possibly a chondrite would  be comparatively 
fresher if one changed the parameters to other ones of interest  to 
researchers. 
 
Saludos, Doug

By  using these numbers you are saying that metal and troilite are not  
weathered."


Hello Jeff, Mike, and List,

If meteoriticists ever  decided to define a weathering scale specifically
for lunar (or Martian)  meteorites, what or which parameters would such a
scale probably have to be  based on?


Cheers,

Bernd
