rutilerich
Rutilerich is a descriptive term used in geology to denote rocks or mineral assemblages that contain an unusually high concentration of rutile, TiO2. The name blends rutile with the adjective-rich, signaling a rutile-dominated or rutile-enriched composition. It is not an official mineral species, but a shorthand used by petrologists to categorize rocks where rutile is a principal titanium-bearing phase.
Geologically, rutilerich rocks typically form in high-temperature metamorphic environments or magmatic contexts where rutile crystallizes readily.
It has economic relevance because rutile is a major source of titanium for pigment production and alloy
