Shale description
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Under the conditions of metamorphism, the calcite in the limestone ...Description. Ashfield Shale comprises black mudstones and grey shales with frequent sideritic clay ironstone bands. The thickness ranges between 45 and 64 metres. [1] It is 20 metres thick at the Sydney Olympic Site. [2] The chemistry of the rock is typical of shales, with high iron levels, and some iron sulphide and low calcium levels.

Phyllite is a very common metamorphic rock, found in many parts of the world. It forms when sedimentary rocks are buried and mildly altered by the heat and directed pressure of regional metamorphism. These are almost always convergent plate boundary environments involving continental lithosphere. Phyllite: A specimen of phyllite exhibiting a ...Apr 25, 2017 · 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.
