Geology

Geoscientists have traced the age and chemical signatures stored in tiny zircon minerals to examine the recycling of carbon through time.

For researchers pursuing the primordial history of oxygen in Earth's atmosphere, a new study might sour some "Eureka!" moments.

Scientists have found evidence showing that three-billion-year old volcanic rock found within the Earth's mantle had a different composition than modern ones. Their discovery may offer new information about the first one billion years of Earth's development and early origins of life.

Scientists say the early Earth was likely to be barren, flat and almost entirely under water with a few small islands, following their analysis of tiny mineral grains as old as 4.4 billion years.

Experimental findings could guide search for exoplanets that may harbor life.

The finding adds evidence to one side of a long-standing debate on how magma from the Earth's mantle cools to form the lower layers of crust.

A team of scientists has found evidence confirming a critical theory of how the planets in our solar system behave in their orbits around the sun.

Geochemist Matt Jackson finds the hottest, most buoyant mantle plumes draw from a primordial reservoir deep in the Earth.

Researchers in Japan say they may be one step closer to solving the mystery at the core of the Earth.

The oceanic crust produced by the Earth today is significantly thinner than crust made 170 million years ago during the time of the supercontinent Pangea.
