Schist is a medium-grade metamorphic rock with medium to large, flat, sheet-like grains in a preferred orientation (nearby grains are roughly parallel). It is defined by having more than 50% platy and elongated minerals, often finely interleaved with quartz and feldspar. These lamellar (flat, planar) minerals include micas, chlorite, talc, hornblende, graphite, and others. Quartz often occurs in drawn-out grains to such an extent that a particular form called quartz schist is produced. Schist is often garnetiferous. Schist forms at a higher temperature and has larger grains than phyllite.Geological foliation (metamorphic arrangement in layers) with medium to large grained flakes in a preferred sheetlike orientation is called schistosity.
The names of various schists are derived from their mineral constituents. For example, schists rich in mica are called mica schists and include biotite or muscovite. Most schists are mica schists, but graphite and chlorite schists are also common. Schists are also named for their prominent or perhaps unusual mineral constituents, as in the case of garnet schist, tourmaline schist, and glaucophane schist.

Schist is a metamorphic rock with visible minerals.
Every rock has a story to tell. No matter what kind of rock, or where you find it, it preserves evidence of its history. And we can learn to decipher that history. Watch this video to learn about a piece rock dubbed the mica schist. This piece of mica schist, now serving as a wall decoration, started its life long before the dinosaurs. It has undergone many changes as it has traveled many miles, both horizontally and vertically, over hundreds of millions of years. The geologic history of the Mica Schist in the Brown Science Center.

Here we show how to split a schist with simple tools. Enjoy.
ABSOLUTELY STUNNING SPECIMEN WITH LOTS OF GARNET ON SCHIST -- AND ONE BIGGUN!
The mysterious schist disk on display in the Egyptian museum of antiquities, in Cairo. It's true purpose remains unknown, but just how was this enigmatic piece even created in the first place? https://www.egyptunlocked.com Author: James Byram Video: Claudio Curciotti https://www.claudiocurciotti.com Music: IQbit https://soundcloud.com/iqbit
http://www.epictv.com The boys' cross-country climbing trip is just getting underway - the camper is cleaned, painted and prepped. First stop in the video series, a local climber's favorite: Rumney, New Hampshire. Rumney is a perfect, small New England town with instant access to a huge outcropping of world-class schist. The campground is comfortable and homey, but the rock climbing is powerful and bouldery sport route climbing - a perfect warm-up for the next area: The Gunks!!

The #Schist_disk is an utterly amazing artefact from the tomb of #Sabu, #Saqqara of the 1st dynasty. We propose that this disk is in fact METAL but COATED in stone! That's right, the Egyptians had high technology abilities of their own, they were able to coat in enamel, glaze, Egyptian Blue, this too is similar. We also suggest the video could be WAY older than it seems to be it simply does not match the artefacts found in the rest of the tomb. All about the Schist Disk. This disc appears to be 1st dynasty, found in the tomb of Sabu, but being a component from a machine it does not appear to have been made by the 1st dynasty (could be wrong) and certainly does not match the rest of the artefacts found in the tomb, which seem to be neolithic. The first 'dynasty' appears to have been mer...

Talasnal the schist village When seen from far away, having Trevim as the background, Talasnal is like an illustrated postcard. In this village, the largest of the Serra da Lousã Schist Villages, Nature lives side by side with many entertainment and active sport options. Surrounded by green landscape, the dark houses supporting each other, two traditional olive oil presses moved by water power, and the fountain, all of them surrounded by trees, create the ideal set to feel the spirit of Central Portugal.

This is schist.
The Schist- TMBP
Boy sit down, stand up girls
Ladies we can run this world
Come on take a stand,
we got the whole wide world in our hands
Now imagine if this whole globe was run by jus women
Jeeze cor blimme what a world we would live in
Getting men all hung upon our love until they be sprung
Imagine men on page three posing nude in the sun
AND--- Imagine ladies pimping these guys
Getting them to sell there bodies on the streets at night
Think, we can choose a man then we treat them bad
Get what we want and need then we ditch them Lads---
Call them to attend to our needs
Get a web cam set up so my friends can see
Then make him pole dance on my bed post then expose him
And put his pictures on the net so everybody knows him
Imagine them with stush attitudes
or the had a shy mood so we make the first move
But we use them for ah one night flex
Sayin don't get attached baby boy its just sex
Imagine the first prints on the moon was ah five
And all the world leaders had a trimmed bikini lines
Open your eyes visualise
Picture ah world run by ah female like shy
A female like WHO, a female like You and a female like I
A female like WHO, a female like You and a female like shy
Boys sit down, stand up girls, ladies we can run this world
Come on take a stand, we got the whole wide world in our hands
Now what if let these men live in kennels like dogs
And we only let them out to do the difficult jobs
Its deep, walk them on the streets and leads are on their necks
And I show him to my friends saying he's my new pet
AND--- think if we went Amsterdam
And the red light district was only full of man
Posing nude looking rude in the shop windows
This world feels like heaven Amen the lord know
Jesus come on guys please us
You're the birds and were the geezers
Imagine if guys took pride all the time
Before they had sex waxed there scrotum line
And girls walk around with moustache's and shit
Unshaven legs, unshaved pits
ERGHHH-- Yeah we crossed the line
but men do this shit all the time
Now I'm a males worst nightmare say your prayers
Cos ah bitch with powers gives mans fears
So I'm here to make it known
Ladies we can run this globe
Say were the mayors and government
F-B-I- and the presidents
Hey we could run the whole of the C-I-A
Take over the streets like were G-I Jane
Imagine us on street patrol,
Woman having full control
No more labours, males give birth
And time of the month don't affect us---
So ladies stand up firm, (Firm)
Come on its our turn. (Turn)
To flip reverse this universe
