You can also tell a claystone from a siltstone by rubbing it against your teeth! If it rubs smoothly without friction then it's a claystone. If it feels abrasive then it's a siltstone.
Better don't tell your dentist
This was a lot of my degree. We licked everything. Still do.
Mouthfeel is an incredible sense. Babies learn what the world is by pushing handfuls of it into their mouths. Texture, taste, angularity, porosity, density, degree of lithificaton.... instantly.
*edit: we did not all lick things. There are two distinct schools of thought, and not a lot of fence sitters.
I would absolutely be on the lick things team. I use my mouth as a tool all the time.
This post sounds incredibly weird.
( ͡° ͜ʖ ͡°)
There's a lot of overlap between archeologists and babies.
I find a stone
But is it clay?
Or is it silt?
I cannot say.
I'll rub a bit
Just on my tooth,
If tooth falls out
I'll know the truth.
Maybe you think
My methods strange,
Maybe you think
They cause me pain.
But I'll keep rocks
All in my fist:
Not odd to me;
I'm geologist.
Oh hell yes ヾ(⌐■_■)ノ♪
When I say peat you say peat
peat
...
fuck
You can also differentiate between halite and sylvite using your tongue! Sylvite has a more tingly, "spicier" feeling and taste, whereas halite is simply salt.
