Re: [Geology2] Diatomaceous Earth In That Volcanic Province?

Lin,

What I was asking is what the heck is diatomaceous earth doing in a volcanic province as in how could it have formed there?

As a former pet store hand, we used diatomaceous earth to polish the water in fish tanks. Sometimes what we used was the actual dead diatoms (single celled algae aka phytoplankton) which form organically. But other times, we used Bentonite clay, which is a residue leftover from ancient volcanoes and  is pumice-like on a microscopic level and neutrally sound in water.

Hope that helps...

Would somebody be able and willing to explain to me how this material formed in such an otherwise volcanic region?

From the pages of the Redding Record-Searchlight 50 years ago:

1963: Diatomaceous earth would be mined near Lake Briton by a Covina company.
The D and F Mining Co. bought rights to 1,200 acres of diatomaceous earth.
The company was the only bidders when the U.S. Forest Service offered the deposit for sale.
