The geo-smells are included in the Google Aromabase of over 15M scentibytes and were collected by field geologists using portable odorometers to crush and analyze samples from formations, members, and facies of every major geologic unit. Collection of aromas from igneous and volcanic rocks is currently underway and is expected to revolutionize prediction of volcanic eruptions. Fresh lava has a much different smell than old, cold, flows.
Geologists are only starting to understand how we can use Google Nose for mineral and petroleum exploration and detection of fossils.
