Year-End PEOTS Puns: "Bak Lava," Silt Happens, and the Search for 145+ Minerals Containing Carbon

        Look at that "Ba(c)k Lava!"

So many layers! 

     So much time. . .to deposit silt-sized particles {Silt particles range between 0.0039 and 0.0625 mm, larger than clay but smaller than sand grains.} Because, yes, SILT HAPPENS (It's the motto of Silt, Colorado, on the western slope).

      And, of course, septarian nodules 

     that resemble leopard milk bread. . .

And, back to "ba(c)k lava ;-) :

      Now, to the serious segment of this week's post. Deep Carbon Researchers are challenging all rockhounds to search for the predicted, additional 145+ Carbon Minerals. (Click on the various parts of the diagram in the link to see lists of known carbon minerals, recently discovered ones, and predicted additional carbon minerals.)

      Anyone up for a carbon mineral search, sometime before 2019?

       Merry Christmas, Happy extra-long Chanukkah, good Kwanza, and Happy Everything in the New Year.

Thanks for all the PEOTS Puns along the way,
Steph
