Smithsonian National Museum of Natural History
DEPARTMENT OF
Mineral Sciences
Scientists in the Department of Mineral Sciences seek to understand the evolution of the Earth and Solar System by studying samples from environments ranging from the mantle to mine drainages, from volcanic arcs to the asteroid belt. The department is home to world-class collections of rocks, minerals, meteorites, and gems, as well as the instruments our scientists use to study these specimens in detail.
**While the Smithsonian National Museum of Natural History exhibition spaces are now open to the public, our collections remain closed to most staff and all researchers, and the museum’s COVID-19 loan moratorium remains in effect. Currently, there is no capacity to accommodate collections activities including visits, image requests, loans, and shipments. Do not send packages to Mineral Sciences staff at this time. While there is no current date set for when on-site collections activities will resume, we will update as soon as this changes.**
FEATURED CONTENT
Global Volcanism Program
The Global Volcanism Program seeks to document, understand, and disseminate information about global volcanic activity. Its weekly and monthly reports provide scientists with a record of ongoing eruptions they can use to guide research and hazard management related to volcanoes.
