101019: The Local Quarry

On Tuesday I visited my local quarry. I usually stay away during the Summer months since hornets often make their homes on the undersides of loose rock. So, with Autumn now in residence, it was time. And, thanks to recent digging by the owner, new areas of exploration have opened up.

What I found was that a transitional layer of rock became available, leaving loose rocks that exhibit an interesting mix of the different layers.

The image above is a fine example. The shaley, brittle rocks of the lower level, often laced with colorful staining, seldom have much in the way of fossils.The surrounding rocks are from the upper layer, where the fossil “motherlode” usually resides.

The opening image, with a well delineated brachiopod sitting next to a yellow streak of chemical oxidization, exemplifies that mixing.

So, I was struck by colors and fossils, sometimes separately and sometimes together. I even found a couple of images (at the end of today’s grouping) that display the unintended handiwork of nature!
