Comparison Chart: Slate Tile vs. Travertine Tile vs. Porcelain Tile: Slate Tile Travertine Tile Porcelain Tile; What is it made of: Slate is a metamorphic rock formed at coastal regions, as the result of silt from ancient oceans subjected to tremendous heat and pressure, for over millions of years after their recession.
The fake Coach purse you bought online to save a few bucks will most likely fall apart in a month, but putting Synthetic slate on your roof will actually be more durable then authentic slate!
Shale has quite a dull look whereas slate shines and looks silky in the sun. The process of formation of rocks is different for various rocks. Siltstone, shale and mudstone are varieties of sedimentary rocks. Slate is composed mainly of clay minerals or micas, depending upon the degree of metamorphism to which it has been subjected. Shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles. In slate, the heated and compacted minerals slowly flow and align themselves perpendicular to the axis of compression, to create "cleavage," which is the tendency of the rock to break along straight lines.
An ecological blogger, technical writer and trainer, Alex Silbajoris also leads a nonprofit watershed group. I want to use some rock in the scaping, and I know it's either slate or shale. 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. The streak of Slate is light to dark brown while that of Shale is white.

As verbs the difference between slate and shale Organic content of just a few percent produces a black shale; calcareous minerals turn shale gray or light gray; and iron oxide or iron hydroxide can cause reddish, yellow or brown colors. In the early stages of slate's composition, mica sediments were compacted and water was forced out of the clay, forming shale.
The specific heat capacity of Slate is 0. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc. Slate is heat resistant, impact resistant, pressure resistant, wear resistant whereas Shale is heat resistant, impact resistant. Moving on, when treated with water, shale will give you an odour like clay but slate will usually not have any noticeable odour. When shale is buried deeper, for a longer time, and heated by the Earth's crust, it forms slate.
Up to the midth century, the term "slate" often referred to shale, slate, and schist. Unlike shale, slate is hard enough to be useful as a structural material in its intact form. Shale is bedded in thin layers as the sediment particles are flattened into parallel sheets, which is called "foliation. Slate and Shale are both metamorphic rocks but both contain different materials.
From German Schalstein laminated limestone, and Schalgebirge layer of stone in stratified rock. Here you can know more about Slate and Shale. Many of the items sold today for landscaping flagstones, retaining walls and construction chalkboards, roofing tiles, pool tables, etc. Shale is too soft for such applications, but as National Geographic explains, some kinds of shale have enough organic hydrocarbons, called kerogen, to make "oil shale," a potential energy source.
Mudstones and shales are made of silt- and clay-sized particles that are too small to see. Shale is a fine-grained, clastic sedimentary rock, composed of mud that is a mix of flakes of clay minerals and tiny fragments silt-sized particles of other minerals, especially quartz and calcite.
Shale, Slate, and Schist. Shale is sedimentary rock, lightly compacted into thin, crumbly layers. Slate is much more durable than shale due to the metamorphic process it undergoes. Slate and shale are similar in appearance. Visually, it can be hard to tell the two apart. Both types of rock break apart in layers and both types of rock also come in the same set of colors, with shades ranging from gray to black.
The biggest difference, noticeable when handling the rocks, is in both the hardness and the different uses for each of the two unique types of rock. Shale is the softer of the two rocks.
Later they may also be overlain by sandstone or limestone. The weight of the overlying material, over millions of years, compacts the sediments into shale. Shale is bedded in thin layers as the sediment particles are flattened into parallel sheets, which is called "foliation. Organic content of just a few percent produces a black shale; calcareous minerals turn shale gray or light gray; and iron oxide or iron hydroxide can cause reddish, yellow or brown colors.
Slate is one stage in the metamorphosis of shale, a sedimentary rock, to gneiss, a metamorphic rock. Slate can also form from volcanic rock. In slate, the heated and compacted minerals slowly flow and align themselves perpendicular to the axis of compression, to create "cleavage," which is the tendency of the rock to break along straight lines.
Like shale, slate has various colors; sometimes it is streaked by the flowing of the minerals. Unlike shale, slate is hard enough to be useful as a structural material in its intact form. Billiards tables use it as a flat, inflexible base for a playing surface. It's cut into pieces for paving walkways, and for flooring. Because slate can be split along its cleavage planes, it has traditionally been used to make durable shingles for roofs.
