  1. The contact between the metasedimentary Fauquier Formation (uppermost marble member) and the overlying metavolcanic Catoctin Formation is exposed in an abandoned quarry north of Aldie, Virginia, across Goose Creek from Lime Kiln Road. The nature of this contact (is it conformable? does it show primary or tectonic struc...

  7. This sample was collected from the Ediacaran Period (ca. 550 Ma) Blueflower Formation in the Mackenzie Mountains of arctic Canada in 1994. The elephant skin is interpreted as the remains of a microbial mat on which, or beneath which, Ediacara organisms lived. This sample was contributed by Dr. Jay Kaufman of the Un...

  8. Dr. Jay Kaufman of the University of Maryland, who provided this sample, interprets these to be microbial sulfate reduction spots on the bedding surface of the Neoproterozoic (Cryogenian) Santa Helena Formation of the Bambui Group in south-central Brazil. The microbial spots show clear cores and cortices, which notabl...

  9. This sample was contributed by Dr. Jay Kaufman of Univeristy of Maryland. Writes Dr. Kaufman: "This slab, which is about 3.5" across, comes from the ca. 3.5 billion-year-old Barberton Mountainland greenstone belt. Lapilli form during volcanic eruptions into a wet atmosphere by accretion around a central nucleus of ...

  10. Banded iron formation. The greyish color is specular hematite, the red is jasper, and the gold is tiger's eye. Sample is 26 cm across at its widest point, and was contributed by Dr. Jay Kaufman of University of Maryland.
