How does slate form naturally?
Naturally slate is formed by the alteration of a shale-type sedimentary rock that consists of clay or volcanic ash through regional metamorphism – mainly under low-temperature and pressure. It is the finest grained foliated metamorphic rock and its foliation is referred to as slate cleavage.

What is slate rock?
Slate is a fine-grained metamorphic rock that shows no obvious compositional layering, but can easily be split into thin slabs and plates. It is usually formed by low-grade regional metamorphism of mudrock. This mild degree of metamorphism produces a rock in which the individual mineral crystals remain microscopic in size, producing a characteristic slaty cleavage in which fresh cleavage surfaces appear dull. This is in contrast to the silky cleaved surfaces of phyllite, which is the next higher grade of metamorphic rock derived from mudstone. The direction of cleavage is independent of any sedimentary structures in the original mudrock, reflecting instead the direction of regional compression.
What is foliation in slate?
The foliation in slate is called " slaty cleavage ". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression.
Why is slate considered a metamorphic rock?
Because slate was formed in low heat and pressure, compared to a number of other metamorphic rocks, some fossils can be found in slate; sometimes even microscopic remains of delicate organisms can be found in slate.
What is slate cleavage?
Slaty cleavage is continuous, meaning that the individual cleavage planes are too closely spaced to be discernible in hand samples. The texture of the slate is totally dominated by these pervasive cleavage planes. Under the microscope, the slate is found to consist of very thin lenses of quartz and feldspar (QF-domains) separated by layers of mica (M-domains). These are typically less than 100 microns thick.
Why is slate used in a lab?
Because it is a good electrical insulator and fireproof, it was used to construct early-20th-century electric switchboards and relay controls for large electric motors. Due to its thermal stability and chemical inertness, slate has been used for laboratory bench tops and for billiard table tops.
What are the minerals in slate?
Slate is mainly composed of the minerals quartz, illite, and chlorite, which account for up to 95% of the composition of the slate. The most important accessory minerals are iron oxides (such as hematite and magnetite ), iron sulfides (such as pyrite ), and carbonate minerals.
What is Slate Used For?
Slate can contain trace metals within the stone, and uneven heating in a microwave or oven may cause the slate to break
HOW DOES SLATE FORM?
Slate is formed through the regional metamorphosis of mudstone or shale under low-pressure conditions. When shale or mudstone is exposed to heavy pressure and heat from a tectonic plate activity, its clay mineral components metamorphose into mica minerals. Mica minerals such as biotite, chlorite, and muscovite, are the main components of slate. One unique characteristic of slate is that it is formed through the process of foliation, which refers to the repetitive lamination of metamorphic rocks caused by shearing forces or differential pressure. Layers of rocks are then formed perpendicular to the direction of the pressure of metamorphic compression. This gives slate its ability to cleave along flat planes. It is considered as the finest grained foliated metamorphic rock, having 0.01 mm or less of space occurring between each layer or lamina.
WHAT IS THE COMPOSITION OF SLATE?
It is mainly composed of quartz and muscovite or illite. Some minerals like biotite, chlorite, hematite, and pyrite are also usually present in slate. Apatite, graphite, kaolinite, magnetite, tourmaline, and feldspar are sometimes present as well, although less frequently. Some compound mineral can also be found in slate. This includes aluminum oxide, iron oxide, potassium oxide, magnesium oxide, sodium oxide, silicone dioxide, and titanium dioxide.
What is the best foliated metamorphic rock?
Slate is considered as the finest grained foliated metamorphic rock. Metamorphic rocks are formed from the change in form of existing rocks, a process called metamorphism. Slate arises from the repetitive layering or foliation of metamorphic rocks, particularly through the low-grade metamorphism of shale or mudstone. It is widely used in building roofs and floors, for it being fireproof and a good electrical insulator. It has also been popular in the use for billiard table tops, blackboards, tombstones, and commemorative tablets. It is widely used as a roofing material because of its low water absorption index of less than 0.4%, making it resistant to frost damage and breakage secondary to freezing.
How long does slate roofing last?
Roofs made of slate can last for hundreds of years. However, slate is quite more expensive than other available roofing materials, and its installation cost more as well. Hence, the use of slate in the more recent times has been mainly restricted to high-end projects and prestige architecture.
Why is slate a thin sheet?
Because of the parallel alignment of the minerals composing slate , it is able to undergo the process of repeated layering or foliation. The parallel alignment of minerals gives the rock the ability to break evenly along the planes of foliation. This is called the slaty cleavage, which gives the rock the ability to split into very thin layers. There is approximately 0.1 mm or less of space between the foliations. Slate, therefore, can be produced in thin sheets that are mostly used in construction and manufacturing industries.
Where is slate made in Spain?
