Can other minerals scratch the hematite?
Yes, other minerals can scratch hematite. Hematite has a hardness of 5.5-6.5 on the Mohs scale, so minerals with a higher hardness (like quartz or corundum) can scratch hematite.
What is the word equation for the reaction that happens when iron forms a hematite in the Earth?
The word equation for the reaction when iron forms hematite in the Earth is: Iron + Oxygen → Hematite.
What group does hematite belong to?
Magnetite belongs to the spinel group of minerals
How are clastic sedimentary rocks divided?
Clastic (or detrital): Sedimentary rock formed from particles of other sedimentary, metamorphic, or igneous rock which has been weathered, eroded, deposited, compacted and cemented. Examples of clastic sedimentary rock include shale, sandstone, mudstone, and conglomerate.Chemical: Chemical sedimentary rocks have intergrown mineral crystals that are precipitated from saturated aqueous solutions and chemical residues. The precipitated minerals that are commonly included are halite, quartz, limonite, calcite, chert, dolomite, hematite, and gypsum; consequently, common chemical rocks are limestone, chert, and rock gypsum.Organic:Organic sedimentary rock is rock that is derived or generated from sediments that are produced by organisms. Coal and chalk are examples of organic sedimentary rock.
Where does hematite rock come from?
Hematite is a mineral that forms in a variety of environments, including sedimentary, igneous, and metamorphic rocks. It typically occurs in iron-rich sedimentary deposits and hydrothermal veins. Hematite can also form directly from the weathering of iron-bearing minerals.
What is an example of an oxide mineral?
Hematite is an example of an oxide mineral. It is composed of iron oxide and is commonly found in sedimentary rocks, soils, and ore deposits. Hematite is characterized by its reddish-brown color and metallic luster.

Is chert metamorphic sedimentary or igneous?
Brick is baked mud, and as such, can be considered to be sedimentary.
Is hematite extrusive or intrusive?
Hematite is commonly found as a sedimentary mineral in deposits like banded iron formations. It is not typically associated with igneous rocks, so it is neither extrusive nor intrusive in the conventional sense.
Is hematite a mineral element?
Hematite is a mineral. This is from wikipedia: A mineral is a naturally occurring solid with a definite chemical composition and a specific crystalline structure. A rock is an aggregate of one or more minerals. Have a look at this page in wiki about hematite: http://en.wikipedia.org/wiki/Haematite
What is the chemical which gives red color to red sandstone?
The red color in red sandstone is primarily due to the presence of hematite, which is a form of iron oxide mineral. Hematite is known for its red coloration and is commonly found in sedimentary rocks like sandstone.
Can solid be hematite or brick?
hematite
What is a hemitite?
Hematite, also spelled as hæmatite, is the mineral form of Iron(III) oxide (Fe2O3), one of several iron oxides. Hematite crystallizes in the rhombohedral system, and it has the same crystal structure as ilmenite and as corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950°C. Hematite is a mineral, colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While the forms of hematite vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle. Maghemite is a hematite- and magnetite-related oxide mineral.
What is the metal in hematite?
Hematite is an ore of iron.
Is Hematite a mineral?
Yes, hematite is a mineral.
What is Rainbow Hematite?
Hematite intermixed with Goethite is also known as Rainbow Hematite and is wonderfully iridescent.
