Mining

Gabbro cools slowly because it forms beneath Earth's surface through the slow cooling and solidification of magma. This allows large mineral crystals to form, giving gabbro its characteristic coarse-grained texture.

Some resources extracted from the earth include metals (such as copper, gold, and iron), fossil fuels (like coal, oil, and natural gas), minerals (such as salt and limestone), and precious stones (like diamonds and emeralds). These resources are used in various industries for manufacturing, energy production, construction, and technology.

A Geoist seeks to tax shift from taxing production - wages, sales, capital - to taxing the use and abuse of natural resources and the locational rent of land. The Land (classically defined as ALL natural resources of the world) is created by nature, not Man, and rightfully belongs to all of us, Geoists argue, and location and demand of rising populations give it its value, not anything private holders of Land do with it, so its value should be returned to the community that gave it its value. Productive activities should be simultaneously untaxed.

Granodiorite is formed from the slow cooling of molten magma beneath the Earth's surface. It is a coarse-grained igneous rock that typically contains quartz, feldspar, and biotite or hornblende. The slow cooling allows for the growth of large crystals within the rock.

Red Earth minerals are found in various regions around the world, including Australia, South Africa, parts of the United States, and Brazil. These minerals are typically formed from iron-rich rock weathering, which gives them their distinctive red color.

A person who searches for surface gold could be called a "prospector."

Common rocks that are quarried include granite, marble, limestone, sandstone, and basalt. These rocks are used for various construction purposes, such as building materials, countertops, monuments, and decorative elements.

Deep lead mining refers to the extraction of lead ore from deep underground mines. This process involves digging shafts and tunnels to access the lead deposits found deep within the earth. Deep lead mining can be a dangerous and challenging endeavor due to the depth and complexity of the mines.

ore deep beneath earth's surface is mined by drilling holes in the earth's crust so that mines can be built for excavation in which the ore is generally mined near but not to close to the base of a dormant volcano as not to activate the volcano.

Jade is formed most commonly through metamorphism associated with subduction faulting along tectonic plate boundaries. A high pressure and low temperature metamorphic environment necessary to form jade.

A coal company might impose a 250 ft depth limit to ensure the safety of miners, prevent risks associated with deep mining such as rockfalls and gas build-up, and comply with environmental regulations relating to groundwater contamination or subsidence. This depth limit could also be set to minimize costs and optimize operational efficiency by focusing on more accessible and profitable coal seams.

Shale forms from the compaction of mud or clay sediments, often in quiet water environments such as lakes or deep ocean basins. These sediments are typically rich in fine particles such as clay minerals and organic matter, which bond together to create the layered structure of shale.

Perfect cleavage results in a thin sheet of a mineral. This occurs when the mineral breaks along flat, parallel planes.

the most desirable form of iron ore because they contribute the most to the productivity of the blast furnace.

A method of forming lump ores is provided which includes the steps of admixing a finely divided metal containing ore with an oxide or hydroxide of an alkaline earth metal, and a small amount of sulfur together with sufficient moisture to permit formation of aggregates such as lumps, pellets or blocks, forming the mix into aggregates, reducing the moisture to below 10 percent, subjecting the aggregates to carbon dioxide atmosphere to convert a substantial part of the alkaline earth metal oxide or hydroxide to carbonate in situ, and recovering the aggregate ore product so formed.

A nugget is a chunk of native gold metal- while fairly pure, may contain traces of other metals. In mining, Reef refers to a vein of high grade ore. Alluvial gold is gold that has been moved and ground down by water- such as the placer gold (gold dust) found in river and stream beds.

Sandstone is typically quarried, not mined. Its natural deposits are found close to the surface and are extracted by cutting blocks or slabs from the quarry walls. The process is less intensive than traditional mining methods used for minerals like coal or iron ore.

Surface mining involves extracting minerals or other materials from the Earth's surface rather than digging underground tunnels. It can cause environmental damage through habitat destruction, soil erosion, and water contamination. However, it is often more cost-effective and efficient than underground mining for extracting resources like coal, gravel, and sand.

Copper ore is mined in various countries worldwide, with significant producers including Chile, Australia, Peru, China, and the United States. These countries have large deposits of copper ore and well-established mining operations.

Yes, there is both nephrite and jadeite in Washington State. Washington is one of approximately half a dozen states where jade is found--in fact Washington has commercial jade mines and much of it is exported to Asia (esp. China) to be carved. The jade found commercially in Washington can fetch prices well over $1000 a pound or as little as being worthless, except as land fill or to throw at mean dogs. Washington jade is perhaps the most varied in color and types. Colors vary from orange to yellow to green to black to white, grays, olives, etc. Some varieties, such as botroidal (sp?) has a knobby, toadskinlike appearance, black, white, apple green, and clear (no color) varieties are very rare and are very much sought after. Much of the jade found reacts to magnets (has high iron content). Much of the jade, especially that found in river banks and glacial tills, has developed an oxidized rind from exposure to the elements. This rind, sometimes thick, sometimes thin, makes finding jade very elusive to the untrained eye. In other cases, especially jade found in and around fast moving cascade mountain streams, have no rind, and are very easily identified by its green color when wetted. This is the method I use most of the time. Over the last 40 years I have probably found over a ton of Washington jade and find that gem quality material can be found in the most gungy looking pieces.

(P.S. NEVER FIELD TEST A GEM STONE WITH YOUR ROCK HAMMER!!! ...wait till you get home and can cut them properly with a rock saw, otherwise you may ruin a stone worth literally $1000's of dollars and turn it into worthless landfill material.)

There is no gem grade jadeite that has ever been verified by testing in Washington State nor is there any commercial jade mines listed in official documents from state government mining departments.Any claims that gem grade jadeite exists in Washington state or that their are commercial jade mines are bogus.

John Milne, a British mining engineer, invented the seismograph in 1880. His device was crucial in the early detection and measurement of earthquakes, greatly advancing the field of seismology.

The large diversity of silicates can be attributed to the variations in the chemical composition, structure, and bonding of silicon and oxygen atoms, as well as the presence of other elements in the mineral structure. Different combinations of these factors lead to a wide range of silicate minerals with unique properties and characteristics. Additionally, external factors such as pressure, temperature, and geological processes contribute to the formation of diverse silicate minerals.

It is important to distinguish between a mineral and a mineraloid. A mineral is an inorganic, naturally occurring substance that has a characteristic chemical composition, distinctive physical properties, and solid crystalline structure (an order 3 dimensional arrangement of atoms or molecules). If it does not have this solid crystalline structure, it is not a true mineral and is therefore a "mineraloid."
