TL;DR: Rutile is a main entry in the 外星矿物知识引擎 database.
Rutile is a high-grade titanium dioxide mineral found in lunar mare basalts. While less abundant than ilmenite, rutile provides a more concentrated titanium source. Titanium extracted from lunar rutile and ilmenite would be valuable for aerospace structures.
Occurrence
Found in lunar mare basalts associated with ilmenite; present in achondrite meteorites
Significance
High-grade titanium ore; source of TiO₂ for pigments and titanium metal; co-occurs with ilmenite in lunar mare
