shale rock

2

Hey @sixpenceee @sixpenceeeblog , last semester I went on a field trip with one of my geology classes where we study the sediments and structures of rocks. One of the places we visited is in Chestnut Ridge in Orchard Park. This location is known as “Eternal Flame”, because in a crevice in the rock behind a waterfall, there is a fire that never goes out. The reason a fire is possible is because of the surrounding rock called shale, which contains a high methane content. Many researchers do not know why it only occurs in this one particular area, perhaps because there is a bubble that doesn’t allow much oxygen to enter.

Here Barbie and her friend found an outcrop showing some turbation. In particular, this is weather-related turbation. The water in the area was down the hill a ways, so it had no effect on this stone. It is no form of human or animal turbation, so the last thing it must be is weather.

Barbie’s travel partner theorizes that possibly this is due to freezing rain or snow. The trees are encircled enough that this is probably not wind, but if enough rain or freezing moisture gets into the cracks of the rocks, it can expand and break them apart. Since the shape is rough and uneven, and is more “scooped” rather than “snapped,” it is not some kind of pressure or force that broke this apart. This is time and weathering.

Going based on the shape, color, and the stone common to the area, this looks to be mostly shale, with a mix of some limestone underneath. The shale on top is darker and the stone beneath is lighter, signaling that at one point this used to be an entirely separate layer rather than the mixed rock it has been pressed into now. So the area beneath the surrounding stone is a victim of force and pressure, but the weathered break in the stone is not. The patchwork of nearly-porous indents in the top surface is more evidence of rain altering the rock rather than force.

I feel so bad for any geology fans out there with tags full of alien rock people like “fuck I just want to read about shale convergence in metamorphic rock who is this square lady god fukkin dammit”

Leaves, fissile shale layers, and a slowly flowing stream.

People who say fracking instead of freaking seem so passionate about the process of drilling and injecting fluid into the ground at high pressures in order to fracture shale rocks and release the natural gas inside.

Pyrite suns

Some pretty cool things can happen as a dark and stinky organic rich mud filled with the life forms of rot slowly turns into rock in a multiplicity of processes known under the umbrella term of diagenesis. In the first stage water gets squished out of the pore spaces in between the sediment grains as the weight of further sediment being laid down above compresses it, and it often has dissolved elements such as iron and sulphur in it.

In the boundary zone (if there is one, which is not always the case) between anoxic mud and oxygenated water, a stratigraphic hierarchy of microorganisms are at work, each squeezing energy out of the excretory products of the one above along its own chemical and enzymaytic pathways. As you go deeper into the mud the reactions get progressively more anoxic, and ions that started out oxidised such as sulphates get reduced to sulphide. At that point they join with any iron in the solution to produce pyrite, often with the direct help of archaea, in this case as discs of radial fibrous crystals that grew outwards pushing the surrounding mud/shale away as they expanded.

For future reference, just because one is named after a rock does not mean that they will have any more luck investigating a rock than anyone else.

  • (1:53:45) Grog: How could you have a staff and not give it a name?  Shale: Only men name their staffs.
  • (2:11:00) Sam: Grab Shale.  Shale’s a rock.
  • (3:40:22) Sam: Oh gosh this is a ……critical roll.

Hardraw Force Falls in Yorkshire - thought to be England’s highest unbroken waterfall. The falls hit shale at the bottom and the cliff is made of sandstone and limestone layers.
