▼a Though the Precambrian geologic record has to date elucidated numerous features of the ancient geobiological environment, several fundamental aspects of the Precambrian Earth remain enigmatic. This dissertation describes studies using tools from |

▼a It has long been postulated that the Neoproterozoic-Cambrian transition was correlated with an increase in environmental oxygen on the basis of minimum physiological requirements of metazoans through the Cambrian Explosion, as well as isotopic a |

▼a The long-term evolution of Earth's surface temperature through the Precambrian is similarly unconstrained. Paleotemperatures inferred from isotopic compositions of marine cherts suggest Earth's oceans cooled from 70 +/- 15 째C in the Archean. How |
