#Mineral Deposits of the Midcontinent Rift System | @USGS Geonarrative | #geology #StoryMaps

A Geonarrative by the US Geologic Survey using ESRI's StoryMaps platform. About 1.1 billion years ago tectonic forces were ripping the Noeth American continent in half--for a modern analog think East African rift zone. The rift process failed but not before a wealth of metallic mineral deposits--nickel, native copper, copper sulfide, silver, uraniun, iron oxide, cobalt, ...--were empced along the northern section of the rift zone.

This Geonarrative intoduces the MidContinent Rift System (MRS), describes both magmatic and hydrothernal deposits associated with it, introduces a new MRS geologic database, and offers additional resources.
