Slate is a fine-grained, metamorphic rock formed by compression of sedimentary shale, mudstone, or basalt. Gray slate is common, but the rock occurs in a variety of colors, including brown, purple, green, and blue.

Slate was formed under low-grade metamorphic conditions— i.e., under relatively low temperature and pressure. The original material was a fine clay, sometimes with sand or volcanic dust, usually in the form of a sedimentary rock ( e.g., a mudstone or shale). The parent rock may be only partially altered so that some of the original mineralogy ... Burgess Shale.

Description Fragments below exposure of fissile Marcellus black shale at Marcellus, N.Y. The Marcellus consists predominantly of black shale and a few limestone beds and concentrations of iron pyrite (Fe S 2) and siderite (FeCO 3). Like most shales, it tends to split easily along the bedding plane, a property known as fissility.

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.

The only difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms. Both are made of ancient mud. From the point of view of understanding the ancient conditions of sediment deposition, it is more useful to subdivide mud rocks into siltstone and ...

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. Shale is a sedimentary rock.

Hornfels. Hornfels is a fine grained metamorphic rock and It is the group for a series of contact metamorphic rocks that have been baked under high temperatures by the heat of igneous intrusions and as a result, have become massive, splintery, extremely hard, and in some cases exceedingly tough and durable. The generally of hornfels are fine …Shale has a particular connotation in people's minds. Back in the day when I was in school, our professors used the Ingram (1953) classification and told us that shales were fissile and mudstones were massive.

As the fledgling country of Canada developed, it was united by a grand project: the railroad linking east to west. Geological explorations and the development of a tourism industry led to the discovery of the first fossils during the 1880s. The discovery of the Burgess Shale by Charles Walcott in 1909 depended heavily on ...The gas in the Marcellus Shale is a result of its contained organic content.
