the rust-colored stain that tints some desert rocks and soil
Most moon rocks primarily consist of silicate minerals, with plagioclase feldspar, pyroxene, and olivine being the most common. Additionally, lunar basalt, which forms from volcanic activity, is rich in iron and magnesium. The presence of minerals like ilmenite and anorthite also contributes to the unique composition of lunar rocks. Overall, moon rocks are characterized by their low abundance of water-bearing minerals compared to terrestrial rocks.
Carbonaceous chondrites are a type of meteorite that contain a high percentage of carbon and other volatile compounds, along with silicate minerals and metal. They are among the oldest and most primitive materials in the solar system, believed to have formed around the same time as the planets. These meteorites are significant for understanding the early solar system's chemistry and the building blocks of life, as they often contain organic molecules and water-bearing minerals. Their diverse mineralogy and isotopic compositions provide insights into the processes that occurred during the formation of the solar system.
Gabbro is not typically rich in iron. It is a dark, coarse-grained rock made up mostly of calcium-rich plagioclase feldspar and pyroxene minerals. While it may contain some iron-bearing minerals, it is not considered an iron-rich rock.
Skarnification refers to the geological process whereby an existing rock, commonly rich in calcium minerals such as calcite and dolomite, is replaced by calcium-bearing silicate minerals (such as varieties of garnet, pyroxene and epidote) to form a 'skarn'. This process usually occurs due to the infiltration of magmatic or hydrothermal fluids into the existing rock through faults and fractures, and may be associated with the formation of significant economic metal concentrations as oxide or sulfide minerals.
Earth's magnetic reversals are recorded in rocks that contain magnetized minerals, such as iron-bearing minerals like magnetite. When these minerals solidify and align with Earth's magnetic field, they preserve a record of the magnetic field at that time. Scientists can study these rocks to determine the timing and duration of past magnetic reversals.
Iron-bearing silicate minerals in the desert landscape oxidize when exposed to air and moisture, producing iron oxide minerals such as hematite and limonite. These minerals give the soil a red or orange color commonly seen in desert regions.

the equator is a theoretical (man-made) line, so has no bearing on the physical landscape
From their ore's, ie from their individual mineral bearing rocks.

No, uranophane is not an igneous rock. It is a mineral, specifically a hydrated calcium uranyl silicate that is typically found in uranium-bearing deposits.
Iron bearing minerals which oxidise to red/brown Iron Oxides (rusts).
Oxidation is a type of chemical weathering where minerals in rocks react with oxygen to form new minerals. It typically leads to the rusting of iron-bearing minerals in rocks.
Fleece-bearing animals are the natural resources from which wool is produced.
The suffix "-iferous" means "bearing or producing." It is commonly used in scientific terminology to denote something that produces a particular substance, such as resiniferous (producing resin) or nectariferous (bearing nectar).
