What Does Slate Rock Look Like

Slate is a foliated metamorphic rock with fine grains.

What does slate rock look like. True slates do not as a rule split along the bedding plane but along planes of cleavage which may intersect the bedding plane. Slate is a fine grained foliated homogeneous metamorphic rock derived from an original shale type sedimentary rock composed of clay or volcanic ash through low grade regional metamorphism it is the finest grained foliated metamorphic rock. Slate is a fine grained foliated metamorphic rock that is created by the alteration of shale or mudstone by low grade regional metamorphism. He s using a classic middle.

These rocks are typically dark grey but could also be orange red black and light grey. Some other rocks that occur in thin beds are improperly called slate because they can be used for roofing and similar purposes. Where does slate come from. Foliation may not correspond to the original sedimentary layering but instead is in planes perpendicular to the direction of metamorphic compression.

What does slate rock look like. Shale is the most common sedimentary rock accounting for about 70 percent of the rock in the earth s crust. Before we talk about the color it is important to know what exactly slate is in terms of geology. Shale is a fine grained rock made from compacted mud and clay.

What does chalk look and feel like. Slate rock is very smooth. The defining characteristic of shale is its ability to break into layers or fissility. Slate fine grained clayey metamorphic rock that cleaves or splits readily into thin slabs having great tensile strength and durability.

As a metamorphic rock it is easy to understand that it has been modified in one way or another through different means such as heat chemical processes and pressure.
