Minerals and Art: a centuries-old connection

Minerals and Art: a centuries-old connection

Since ancient times, colours have been fundamental for artistic expression: pigments have always been created from fruits, leaves-flowers, and minerals. During the centuries, new material discoveries and techniques increased the shades we can still see and use nowadays. Once upon a Prehistoric time… El Castillo Cave, in Spain, is one of the earliest known cave …[Read More]

Camp Century re-visited: sediment from the bottom of a Cold War ice core reveals Greenland’s warm past

Camp Century re-visited: sediment from the bottom of a Cold War ice core reveals Greenland’s warm past

A Cold War nuclear-powered military base inside the Greenland Ice Sheet sounds like science fiction, but the science that came out of this U.S. army installation was anything but fiction. In last week’s EGU CR blog post, Paul Bierman and Amanda Schmidt discussed the advances made by the U.S. military in operating across the Greenland …[Read More]

TS Must-read – Buck (1991): Modes of continental lithospheric extension

TS Must-read – Buck (1991): Modes of continental lithospheric extension

Buck (1991) aims at solving the  intense ‘70s and ‘80s tectonic debate concerning the way extension is accommodated in continental regions (see our previous blog posts here and here). His article explores the physical conditions that can lead to the three end-member modes of lithospheric extension in continents: core complex mode, wide rift mode and …[Read More]

Living IN the Greenland ice sheet: the story of Sites I and II, Camp Century’s older, smaller siblings

Living IN the Greenland ice sheet: the story of Sites I and II, Camp Century’s older, smaller siblings

Greenland, cold as it is, was appropriately front and center in the Cold War. Strategically placed between Europe and North America, the United States sought to maintain and enhance its position on the island so that American missiles and bombers were in striking range of many Soviet targets. Soviet bombers and missiles coming toward North …[Read More]
