Accessory Mineral - an overview ScienceDirect Topics

Accessory minerals provide powerful, and sometimes unique, insights into continental evolution that far outweigh their size and abundance in crustal rocks. These insights stem from the wealth of chemical and isotopic information harbored by these tiny repositories, including U–Th–Pb isotopes that provide robust chronological frameworks and isotope tracers that fingerprint petrogenetic processes, and the
