A new computational study published in the Proceedings of the National Academy of Sciences reveals how hydrocarbons may be formed from methane in deep Earth at extreme pressures and temperatures. The thermodynamic and kinetic properties of hydrocarbons at high pressures and temperatures are important for understanding carbon reservoirs and fluxes in Earth. The work provides a basis for understanding experiments that demonstrated polymerization of methane to form high hydrocarbons and earlier...

SAN DIEGO, March 23 /PRNewswire/ -- For decades, an unsuspected geological blunder has limited crucial technical understanding of how, where and why petroleum and natural gas deposits form. Exposing and correcting that vital mistake offer the promise of new insights and potentially vast new energy-resource discoveries. Since the 1930s, the idea of mantle convection has been inextricably rooted in common geological interpretations of the Earth's dynamics. In a paper just published in the...

The oil and gas that fuels our homes and cars started out as living organisms that died, were compressed, and heated under heavy layers of sediments in the Earth's crust. Scientists have debated for years whether some of these hydrocarbons could also have been created deeper in the Earth and formed without organic matter. Now for the first time, scientists have found that ethane and heavier hydrocarbons can be synthesized under the pressure-temperature conditions of the upper mantle...

Huge methane gas bursts on Mars appear to be caused by bacteria rather than volcanic activity, U.S. government scientists said Thursday. The researchers at NASA's Goddard Space Flight Center in Greenbelt, Md., did not say what bacteria created the methane, the principal component of natural gas. But their findings, published in the journal Science, suggest the possibility of present-day microbes living on the fourth planet from the sun, The New York Times reported. On Earth, bacteria known as...

Hydrocarbons "“ molecules critical to life "“ are being generated by the simple interaction of seawater with the rocks under the Lost City hydrothermal vent field in the mid-Atlantic Ocean. Being able to produce building blocks of life makes Lost City-like vents even stronger contenders as places where life might have originated on Earth, according to Giora Proskurowski and Deborah Kelley, two authors of a paper in the Feb. 1 Science. Researchers have ruled out carbon from the...

The limits to life have consistently listed carbon-based organisms as central. While methane-consuming microbes are still carbon-based, they do offer novel ways to extract energy even without light or oxygen. Their role in our solar system is a subject of fruitful speculation. Astrobiology Magazine -- A team of University of Minnesota scientists has discovered how iron- and chromium-rich rocks can generate natural gas (methane) and related hydrocarbons when reacted with superheated fluids...
