Protecting the mineral treasures of Antarctica's Larsemann Hills

In 2003, scientists visited the Stornes Peninsula in Antarctica's Larsemann Hills to study the rocks — especially boron and phosphorus minerals. What they found set them on a decade-long path to protect the geology, culminating in 2014 with the naming of the site as an Antarctic Specially Protected Area.

Dangerous dust: Erionite - an asbestos-like mineral causing a cancer epidemic in Turkey - is found in at least 13 states

As North Dakota’s state geologist, Ed Murphy has spent a fair amount of time mapping the geology of the Killdeer Mountains in the western part of the state, hiking up and down buttes of the White River Group and the Arikaree Formation. In the 1980s, he and colleagues mapped large deposits of rocks bearing erionite — a zeolite mineral formed when volcanic ash is altered by water — that may have had some commercial use.

Afghanistan's mineral resources laid bare

A mineral assessment milestone confirms world-class resources

Each donning about 10 kilograms of protective gear, including helmets and Kevlar, scientists trudged up the rugged, rocky volcanic terrain of southern Afghanistan, slowing now and then to catch an extra breath of thin air. Some carried guns. Others carried rock hammers.
