Limonite is a recognized mineral by the IMA, although its chemical structure will vary. As a mineral, it is not classified as igneous, sedimentary, or metamorphic in the manner of rock identification
Moqui marbles are neat little concretions formed in sedimentary rock. Hematite cements the granules together into a hardened spherical mass, then erosion removes the surrounding sandstone.
Yes, hematite can be formed by inorganic processes.
Magnetite belongs to the spinel group of minerals
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.
Brick is baked mud, and as such, can be considered to be sedimentary.

Yes, hematite is a mineral.
Hematite is an ore of iron.
Hematite intermixed with Goethite is also known as Rainbow Hematite and is wonderfully iridescent.
Hematite is a mineral composed largely of iron. Hematite rosary beads would be beads made of hematite used for a rosary.
Hematite is a mineral of iron: Fe2O3.
Hematite has a dramatic red streak.
Moqui marbles are neat little concretions formed in sedimentary rock. Hematite cements the granules together into a hardened spherical mass, then erosion removes the surrounding sandstone.
Hematite is an oxide of iron.
hematite is a mineral that is used for jewelry
