Carbon dioxide and oxygen, not methane, were prevalent in the Earth's atmosphere more than 1.8 billion years ago as shown by the absence of siderite in ancient soils but the abundance of the mineral ...
NASA's Curiosity rover has unearthed compelling evidence of a past carbon cycle on Mars, discovering siderite within Gale Crater's ancient rocks. This finding suggests Mars once possessed a thick, ...
WASHINGTON — A mineral called siderite found abundantly in rock drilled by a NASA rover on the surface of Mars is providing fresh evidence of the planet's warmer and wetter ancient past when it ...
