Temporal trends in Earth's near-surface mineralogy correlate with major events in Earth's geochemical and tectonic history. New and published analyses of 422 molybdenite (MoS2) specimens from 135 localities with known ages from 2.91 billion years (Ga) to 6.3 million years (Ma) reveal two statistically significant trends. First, systematic increases in average and maximum trace concentrations of Re in molybdenite since 3.0Ga point to enhanced oxidative weathering by subsurface fluids. In addition, episodic molybdenum mineralization correlates with five intervals of supercontinent assembly from ~2.7Ga (Kenorland) to 300Ma (Pangaea).
