17-Ice: Stolen moon ice
When you think of ice, you might imagine glaciers, the North Pole, a clink in your water glass. But it turns out that our closest neighbor in space isn’t just a dusty ball—the moon has ice tucked away in deep craters at each of its poles. On top of that, scientists think the moon stole its ice: from comets, asteroids, maybe even from the Earth.

Quarrying soapstone
Earlier this summer, I was lucky enough to visit a soapstone quarrying operation in Schuyler, Virginia, right on the Albemarle/Nelson County line. These soapstone bodies are metamorphosed ultramafic intrusions into the Neoproterozoic sedimentary deposits of the Lynchburg Group. The protolith peridotite sill crystallized at ~580 Ma, meaning the host sediments are older than that (but younger than the Grenvillian basement complex that underlies both). Then both plutonic rock and sedimentary …

Flow from the mining landslide at Pau Branco
Flow from the mining landslide at Pau Branco The mining landslide at Pau Branco caused a significant release of mine waste, which appears to have flowed into the water retention structure below. This image, from the Observatório da Mineração, shows the flow path:- . As the image shows, the landslide overtopped the retaining structure, which remained essentially intact (note the superficial erosion on either side of the dam abutments). The …
