When it reaches the city of Durham the River Wear passes through a deep, wooded gorge, from which several springs emerge, historically used as sources of potable water.A few coal seams are visible in the banks. Twisting sinuously in an incised meander, the river has cut deeply into the "Cathedral Sandstone" bedrock.The high ground (bluffs) enclosed by this meander is known …

The rock salt is mined, crushed to appropriate size, and usually applied to roads and highways without further processing. When applied dry, much of the salt can bounce off of the road or be scattered by the wind of passing traffic. If the salt is applied wet, more of it sticks to the road, and the loss of salt is reduced.
Graphite (/ ˈ ɡ r æ f aɪ t /) is a crystalline form of the element carbon.It consists of stacked layers of graphene.Graphite occurs naturally and is the most stable form of carbon under standard conditions.Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes.Under high pressures and temperatures it …
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism.The original rock is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F) and, often, elevated pressure of 100 megapascals (1,000 bar) or more, causing profound physical or chemical changes.During this process, the rock remains mostly …
Iron ore production in the United States occurs in Michigan and Minnesota. Hematite Pigment: Hematite was one of the first pigment minerals used by people. At least 40,000 years ago, people obtained hematite, crushed it into a fine powder, and used it to make paints.
Hardness. Because the chemical composition of garnet varies, the atomic bonds in some species are stronger than in others. As a result, this mineral group shows a range of hardness on the Mohs scale of about 6.0 to 7.5. The harder species like almandine are often used for abrasive purposes.. Magnetics used in garnet series identification. For gem identification purposes, a …

What is Basalt? Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill.It has a composition similar to gabbro.The difference between basalt and gabbro is that basalt is a …
