organic sedimentary rock
What’s the deal with coal? It’s classified as an organic sedimentary rock, but rocks are combinations of minerals, and minerals are inorganic. Coal is made of decomposed plants, which are organic.
Which one is considered as mineral?
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.
Is coal a mineral why *?
Minerals – Mineral is a naturally occurring inorganic solid with definite chemical composition and a crystalline structure. Coal is not a mineral because it does not qualify to be one. Coal is non-living and made up of atoms of elements. Minerals are not formed from living things such as plants or animals.
What are 3 types of minerals?
Types of minerals
- Native elements. eg. Gold, Silver, Mercury, graphite, diamond.
- Oxides. eg corundum (incl. sapphire), hematite, spinel.
- Hydroxides. eg. Goethite, brucite.
- Sulfides. eg. Pyrite, galena, sphalerite.
- Sulfates. eg. Baryte, gypsum.
- Carbonates. eg. Calcite, magnesite, dolomite.
- Phosphates. eg.
- Halides. eg.
Is Fossil a mineral?
The extraction companies challenged the ruling, and the case made its way to the Ninth Circuit Court of Appeals, which ruled 2-1 this year that, legally and scientifically speaking, fossils are minerals.
Is coal a mineral or a natural resource?
Coal is an abundant natural resource that can be used as a source of energy, as a chemical source from which numerous synthetic compounds (e.g., dyes, oils, waxes, pharmaceuticals, and pesticides) can be derived, and in the production of coke for metallurgical processes.
What minerals are found in coal?
Relatively common minerals found are quartz, pyrite, calcite, dolomite, siderite, and ankerite, etc. Other minerals are seldom found in coal. The occurrence of minerals and mineral aggregates in coal seam appears in the modes of dispersed grains, nodules, lenticles, and bands.
What elements are found in coal?
Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. What elements are in coal – The Q&A wiki it is a fossil fuel -the elements in coal are mainly hydrogen and carbon, with lower levels of hydrogen, oxygen, sulfur and nitrogen, yet some trace elements within
Is coal a rock, mineral or fossil?
Coal is an energy mineral (legally a mineral, scientifically a rock). Coal is fossil fuel (because it is derived from fossil plant remains). Coal is a solid hydrocarbon (because it consists mostly of carbon, hydrogen, and oxygen; in contrast, oil is a liquid hydrocarbon, and natural gas is a gaseous hydrocarbon).
