I have been trying to locate the thread where Laurie got into telling Fire,
and the rest of us, the story of Ebeneezer Emmons famous faux pas
so I could add some pictures of this specimen I found sitting on Laurie's porch.
It's pretty easy to see why ol' Ebeneezer mistook this for a fossil bearing rock.
Here are some quick pics of first Side A, and a close-up
and then Side B and several close-ups.
It is interesting to me how the whole rock seems to have a top and bottom.
I think I'm going to have to halve that rock.

Thanks, kayla.

Yep, It doesn't get any more interesting than that!
It will be interesting to look at this rock closer and to try
and find a similar rock for comparison.
The lines running parallel to each other thru the rock looks like
old signs of "flow" weathering out to me. I'm guessing volcanic igneous.

First pic is the "bottom" of the rock.
Second pic is cut-end dry, third pic is cut-end wet.
Followed by a couple close-ups of the cut-end wet.

All these porphyritic, spherulitic, orbicular jaspers, rhyolites
and whatever, are hard to keep up with.
Just one more comparison;
Look at Raleigh's Amygdule Basalt compared to Austrailia's
Spherulitic Rhyolite, Leopard Skin Jasper.

Just want to post too many pics of another piece of the amygdulitic rhyo-basalt.
First the weathered exterior,

This slab reminds me of a morel.

To anyone who feels up to it, I was told by a well known local collector in the Troy area many years ago about an occurence of "geodes" off Hwy. 24/27 west of Troy. I went there many years ago and found a few small rocks similar to what Joe's showing that had that "ollitic" habit of rounded rock inside a mass of country rock. Anyway, a few did have hollow interiors with micro xlline druzy quartz in them. I went west from Troy on 24/27 and there was a train trussle. I remember parking at this trussle (overpass) and walking north along a path on the west side of the tracks. We only went about 200 yards and the "geodes" were as float along the path and in the wood line. I thought these as odd since I know of very few true geode occurences in NC. These weren't pretty or colorful but a few did have hollow interiors which I guess might qualify them as geodes? As I say, it was at least 25 years ago but I specifically remember going west on 24/27 and parking at a train trussle that crossed the main road. Now if you go that way, the road forks at 109 south and 24/27 and if you go south on 109 towards West Montgomery High School, there was also a road that turned right (west) off 109. That may be the one that has the train trussle and not 24/27? Either way, I'm sure that it is one or them and the train trussle crossed right over the road and it was there one could park, walk back north and find these "possible" geodes. I have no earthly idea what the area looks like today but that area hasn't changed much in many years.
