Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2Si2O5(OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its … See moreOil Shale is a rock that contains significant amounts of organic material in the form of kerogen. Up to 1/3 of the rock can be solid organic material. Liquid and gaseous hydrocarbons can be extracted from the oil shale, but the rock must be heated and/or treated with solvents. Arkose is a feldspar-rich sandstone. It is commonly coarse-grained and usually either pink or gray (depending on the color of feldspar). Arkose is a type of sandstone that contains lots of feldspar grains. A sample from the precambrian of Finland found on the northwestern coast of Estonia where it was left by the receding Scandinavian ...As shale is compressed, it becomes slate. Thiradech / Getty Images. The word "slate" has held different meanings over the years and in various industries. In the past, the terms "slate" and "shale" have been used interchangeably. In the modern usage, geologists say shale is converted into slate. However, if you're looking at a partially ...Permian Basin (North America) / 32.500°N 103.000°W / 32.500; -103.000.

It is the largest and one of the deepest natural gas play in the United States, located directly under the Mahantongo and Tully Limestone formations. It also overlaps its neighboring shale to the north, the Utica. Arkose is a feldspar-rich sandstone.

The Marcellus formation is a part of the ancient sedimentary system known as the Appalachian basin. The organic-rich black shale of the Marcellus formation was deposited in a foreland basin roughly paralleling the structural front of the present-day Appalachian Mountains during the Middle Devonian time about 390 million years ago (Harper, 1999). The Burgess Shale is a fossil -bearing deposit exposed in the Canadian Rockies of British Columbia, Canada. [2] [3] It is famous for the exceptional preservation of the soft parts of its fossils. At 508 million years old ( middle Cambrian ), [4] it is one of the earliest fossil beds containing soft-part imprints. Nov 2, 2021 · Formation of Shale. Shale, like all sedimentary rocks, forms as a result of the compaction and cementation of materials that have weathered and eroded off of other, pre-existing rocks. Quartz. •••. Gold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides. The white color of quartz makes it easy to spot in many environments.
