Data on size and shape characteristics of riebeckite cleavage fragments. The sample was obtained from the Long Valley Creek Quarry, California. Data were collected in ca. 1978-1979. Data values were obtained with Scanning ...

Paleontologists use multiple methods to reconstruct the anatomy and behavior of extinct animals, including direct observations from well-preserved fossils and inferences from the phylogeny of modern and extinct relatives. ...

Genetic contributions to the final stages of planetary growth, including materials associated with the giant Moon forming impact, late accretion, and late heavy bombardment are examined using siderophile elements. Isotopic ...
