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. Most shales are formed in marine environments, with groundwater highly saline. Shale acts as a semipermeable membrane, allowing water to pass through and retaining dissolved stains. Some shales are rich in unoxidized carbon. These are known as black shales, and some of them may also contain heavy metals like uranium, vanadium, zinc, and molybdenum.Several of the rock layers in the canyon are of terrestrial origin, including the Hermit Shale, Supai Group, Coconino Sandstone, and Surprise Canyon Formation. The mudstones and siltstones of the Hermit Shale and Supai Group were laid down by a meandering system of rivers and streams in a semi-arid climate about 280 million years ago.

The Green River formation, an oil-shale formation in Colorado, Utah, and Wyoming, is a potentially valuable source of synthetic crude oil. In eastern Germany and Poland the Kupferschiefer , a bituminous shale , is mined for copper, lead, and zinc.

Shale is a sedimentary rock formed from clay and silt, while slate is a metamorphic rock formed from shale or clay. Shale has a layered structure and is rich in organic matter, while slate has a fissile texture and is highly compressed and durable. Shale is softer and less durable than slate, which makes it more prone to weathering and erosion ...

Shale forms from the pressure of layers of sediment compressing bits of silt that settle into the clay on the bottom of bodies of water. The compressed clay and silt become shale over time.

Several of the rock layers in the canyon are of terrestrial origin, including the Hermit Shale, Supai Group, Coconino Sandstone, and Surprise Canyon Formation. The mudstones and siltstones of the Hermit Shale and Supai Group were laid down by a meandering system of rivers and streams in a semi-arid climate about 280 million years ago.

Shale forms in very deep ocean water, lagoons, lakes and swamps where the water is still enough to allow the extremely fine clay and silt particles to settle to the floor. Geologists estimate that shale represents almost ¾ of the sedimentary rock on the Earth’s crust. Geologists are specific about the definition of the rock called “shale.”

Shale is a fine-grained sedimentary rock composed primarily of clay minerals and other clay-sized particles of minerals like quartz and calcite. It is laminated and fissile, easily breaking along bedding planes. Shale forms from the deposition and compaction of clay-sized minerals in a low-energy environment. This Formation is commonly called Alum Shale because historical raw materials for the production of alum were extracted from this shale.

The upper part of the Early Cambrian sand Formation is composed of glauconitic sandstone which is overlain by gray-green siltstones and shale of Middle Cambrian age.The Appalachian Mountains formed during a collision of continents 500 to 300 million years ago. In their prime they probably had peaks as high as those in the modern zone of continental collision stretching from the Himalayas in Asia to the Alps in Europe. But over the past 300 million years, the Appalachians have eroded to more modest heights.Shale formations are ubiquitous in sedimentary basins and, as a result, the main organic-rich shale formations have already been identified in most regions of the world. The depths vary from near surface to several 1000 feet underground, whereas the thickness varies from tens of feet to several hundred feet.Shale gas. Shale is a fine-grained, sedimentary rock formed as a result of the compaction of clay, silt, mud and organic matter over time and is usually considered equivalent to mudstone. Shales were deposited in ancient seas, river deltas, lakes and lagoons and are one of the most abundant sedimentary rock types, found at both the Earth’s ... Shale oil is extracted by pyrolysis, hydrogenation, or thermal dissolution of oil shale. The pyrolysis of the rock is performed in a retort, situated either above ground or within the rock formation itself.As of 2008, most oil shale industries perform the shale oil extraction process after the rock is mined, crushed and transported to a retorting facility, although …Shale is a lithified mud — a sedimentary rock composed mostly of clay- and silt-sized grains. There are several ways to define shale. Some definitions are rather narrow.
