Shales changed form?
Slate is metamorphosed shale.
How does schist form from shale?
Shale rocks are formed in the deep waters of swaps, oceans and lakes where the water is still and the fine clay and silt particles are able to settle to the floor. Shale rocks can easily erode due to weathering.
Is slate a mineral or rock?
Slate is made up of mostly of quartz and muscovite, often with some biotite, chlorite, and/or hematite. Small quantities of apatite, graphite, kaolin, magnetite, tourmaline, and zircon may also be present in measureable amounts.
What turns sediment into shale?
Silt and clay size sediments form shale.
How are Slate caves are formed?
Caves do not form naturally in slate with the possible exception of sea-caves (and then would be inherently unstable) and shallow rock-shelters. Slate mines (entirely artificial) can be very extensive but these are man-made.
Shales changed form?
Slate is metamorphosed shale.
From which rock type does slate form?
The most usual protolith of slate is the sedimentary rock shale.
What does shale form into once it is a metamorphic rock does it form into anything?
It tuns into slate when matamorphosed.
What kind of rock is formed from the metamorphic of shale?
The first metamorphic rock to form from shale is slate. With further metamorphosis you get phyllite, then schist, then gneiss.
Does shale form from gneiss?
It can, indirectly. Shale is a sedimentary rock. Like many rocks, gneiss can be weathered down to very fine particles to the point that it becomes clay or silt. Those particles can then settle on the bottom of a body of water as mud. Under the pressure of burial, that mud can become shale. However, gneiss can also form from shale. Under long exposure to enormous heat and pressure shale will becomes slate, further heating and pressure will turn slate into phyllite, phyllite into schist, and schist into gneiss.
What rock do schist rocks form from?
If you apply shale with intense heat and pressure. you'll get slate. Now just apply intense heat and pressure to the slate an over time you'll get your schist
Can shale change into slate?
From depth of burial by continual sediment deposition from above, or from compressional stress from tectonic plate collisions, shale is metamorphosed into slate over periods of millions of years. During this compression, the clay minerals making up the shale decompose as they become unstable in the high pressure environment, and their chemical components are gradually transformed into minerals that are more stable in the newly forming higher pressure environment. A more stable high pressure mineral is mica, consisting of flat individual crystals. The mica minerals form in the shale and align themselves at right angles to the direction of the pressure producing a metamorphic rock layering known as foliation. The foliation in slate creates cleavage planes that will bear no relationship to the original bedding planes found in the parent rock, shale.
Where do shale rocks form?
Shale is sedimentary, and is normally formed at the bottom of bodies of water. It is today found on mountaintops sometimes, but that is because of the "pushing up" action of plate tectonics. It is most commonly found at ground level, though.
How do flat form?
Mos flat rocks are sedimentary, with shale being a prime example. Shale forms from fine sediment being laid down in layers and then later hardened into rock, with the layers preserved. Slate is a metamorphic rock derived from shale that still preserves the layering.

What sedimentary rock does does slate come from?
Slate is a metamorphic rock formed form a sedimentary rocks called shale (which is made up of fine grained clay particles) when it is subject to a regional metamorphic event. A regional metamorphic event would see the shale burred to a great depth (about 20 Km and heated to about 400 degrees Celsius) and then compressed by mountain building forces (the collision of continental plates). Under these conditions new malicious minerals form with their flat sides at right angles to the main compression force and the rock develops a new slatey fabric (along which it can be split) turning it into slate.
How does slate form?
Slate is formed by the effects of heat and pressure on the rocks shale or mudstone. The source of the heat and pressure is usually from depth of burial or tectonic plate collisions, where shale is put under tremendous directional pressure. The pressure causes an alignment of the constituent minerals in the shale, creating a foliated or platy texture, characteristic of certain metamorphic rocks.
