Rock inquiry

Forums:

so we find these on our logging roads.  

Anyone know what type of rock it is?  

The grey is basalt, and white is quartzite?

It's quarried from basalt bedrock, I'm guessing.IMG_7514.JPG

Paging Noodler to the white courtesy telephone, please.

Second from left looks like columnar crinoid 

Germany, and "The Bay of Fundy in Nova Scotia, New Jersey, Oregon, and British Columbia have also produced excellent specimens."

We're in good company.

All that undersea pillow basalt in the coastal volcanics (and Cascades to a lesser extent), excellent sources for many types of zeolites...

Use to find world class examples in the quarries off Price Ck Rd in Kings Valley, Benton Co Oregon, before it got gated off...  here's a few examples;

That middle pan is zeolites;

Awesome.  Wiki gives some great scrabble words... ~ epitaxial ~  and, of course, zeolite.

What is interesting about these buggards is that they seem to erupt overnite.  I walk the same route sometimes daily, and find news ones, more erumpent, & think I'd would have seen them the day before...

I think they jump.  is that possible?

You should find the quarry they're coming from, could be some excellent collecting possibilities 

We have 'em in our driveway rock. They often create a weak spot in the rock where it's likely to break, and show a new zeolite surface. Thus, the appearance of "new ones" from time to time.

Surf, that makes sense.

And...so does this....rocks moving in Death valley ~

Yup, those are definitely rocks!

Maybe me and disco stu can harvest some joisey ones now that I'm back in the midatlantics again
