Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.Oil shale - Pollution, Mining, Energy: The production of oil from shales has a potentially serious impact on the environment. Four specific areas of concern dominate discussion regarding development of the resource: greenhouse gas output, water consumption and pollution, surface disturbance, and socioeconomic effects. Because oil and gas are produced by heating oil shale and because heating ... 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.

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.

Examples of intrusions include sills (horizontal layers of rock) (e.g. the Palisade sill), dikes (vertical intrusions) and plutons (large masses). Extrusives include lava, pumice, and ash from volcanoes. (Note: lava refers only to a particular form of extrusive igneous rocks.) Station 3 Breccia forms where broken, angular fragments of rock or mineral debris accumulate.

In order for a rock to be named a siltstone, it must contain over 50% silt-sized material. Silt is any particle smaller than sand, 1/16 of a millimeter, and larger than clay, 1/256 of millimeter. Silt is believed to be the product of physical weathering, which can involve freezing and ...How Does Phyllite Form? Phyllite was originally a fine-grained sedimentary rock such as shale or mudstone, composed mainly of clay minerals in a semi-random orientation.

Shale forms via compaction from particles in slow or quiet water, such as river deltas, lakes, swamps, or the ocean floor. Heavier particles sink and form sandstone and limestone, while clay and fine silt remain suspended in water. Over time, compressed sandstone and limestone become shale.Shale forms in an environment that consists of calm water: for example, water near the shores of large lakes or continental shelves at sea edges. The calmness of the water allows suspended particles like clay to eventually sink and settle in the bottom of the lake or sea. ... and form shale.

When carbon-rich organic materials, such as leaves, are deposited in stagnant water such as a bog or swamp with a low oxygen content it may not fully decay. If this happens and sediment is deposited on top, a coal bed can eventually form. Many of the largest coal beds in the world ...Dec 4, 2017 · Shale is made of fine clay particles, and therefore indicates deposition in relatively still water. In contrast, sandstone is made of slightly larger grains and therefore deposition of sand can happen in water that is moving slowly.
