The Global Factors of Lead–Zinc Ore Formation

2020-1-27  Abstract The tectonic evolution of the Earth is the leading factor that accounts for the uneven distribution of lead and zinc reserves through geologic time. The cyclic changes in lead–zinc ore formation productivity reflected the periodic amalgamation of most continental crustal blocks and supercontinent formation, stabilization, and eventual breakup. Many features of the age spectra of ...
