The Astrogeology Terrestrial Analog Sample Collections include three individual sample collections: the Meteor Crater Sample Collection, the Flynn Creek Crater Sample Collection, and the Shoemaker Sample Collection (embed links to individual pages; add buttons to click to go to individual pages).
Click Related Science tab above to navigate to the individual collections pages.
Geologic samples from these collections are available to scientists in the planetary science community. The geologic materials in the collections include impact crater drill cores and cuttings; unique and irreplaceable geologic hand samples, rock powders, thin sections and billets, and associated data and documentation, from impact craters, and other terrestrial analog sites, from around the world. These sample collections and data are an essential part of the legacies of Eugene Shoemaker and David Roddy.
Samples from the collections can be used for geochemical and geophysical studies of planetary impact cratering dynamics, such as complex impact crater formation and morphology, impact-induced hydrothermal systems, impact melting of sedimentary targets, and mineral shock metamorphism. Given the modern financial and logistical difficulties inherent in conducting thorough field sampling campaigns, preservation of and access to these sample collections is a fundamental part of Astrogeology’s Terrestrial Analog Program.

Shoemaker Sample Collection
The USGS Shoemaker Collection consists of unique and irreplaceable geologic hand samples, rock powders, petrographic thin sections and billets, and associated documentation, from impact craters and terrestrial analog sites around the world. Current curation efforts are focused on data rescue, preservation, and inventory. All geologic materials are being relocated into appropriate long-term storage...Meteor Crater Drill Cores
While inventorying the drill cuttings from Meteor Crater, we identified 31 boxes of drill core from the crater. Unfortunately, there was little or no documentation for these cores and we initially did not know the drill hole locations or any of the ancillary details. With the assistance of Dr. David Kring, we eventually determined the origin of all of the drill cores. We found that they were...Meteor Crater Sample Collection
Meteor Crater is a 180 m deep, 1.2 km diameter bowl-shaped impact crater in Northern Arizona, and has long been a terrestrial analog site for planetary exploration. During the 1960’s, Eugene Shoemaker trained NASA astronauts at the crater to prepare for the Apollo missions to the Moon. The Meteor Crater Sample Collection consists of geologic samples from the Meteor Crater ejecta blanket. USGS...Flynn Creek Crater Sample Collection
Flynn Creek crater is a 3.8 km diameter, 360-million-year-old impact structure located in north central Tennessee, and is an invaluable terrestrial analog for the study of impact cratering dynamics. The Flynn Creek Crater Sample Collection consists of over two thousand boxes of drill core from 18 drill holes in the crater’s central uplift, floor, and rim. USGS Astrogeology curates and provides...
