U.S. Geological Survey Gas Hydrates Project. Gas hydrate is an ice-like crystalline form of water and low molecular weight gas (e.g., methane, ethane, carbon dioxide).On Earth, gas hydrates occur naturally in some marine sediments and within and beneath permafrost. Gas hydrates have also been inferred on other planets or their moons.ethane molecules can fit within both the small and large sites in the Structure I lattice, and Structure I methane hydrate is indeed the most common type found in nature. Thus, âgas hydrateâ and âmethane hydrateâ are often used interchangeably by researchers.
As earlier said, helium occurs naturally in the universe in vast quantities, though on Earth it is relatively scarce. It is usually found in natural gas pockets in concentrations as high as 7 percent. When the planet formed, some 4.6 billion years ago, virtually no helium was present. Currently however, some 3,000 tones of this element are generated by Earth's crust every year.
