摘要：

He, Ar, Ne contents and He-3/He-4, He-4/Ne-20, and Ar-40/Ar-36 ratios in gas-hydrate bearing sea-floor sediments of the Hakon Mosby Mud Volcano show that Ne, Ar, and part of He are atmospheric. Nonatmospheric, deep He (He-3/He-4 = 0.9.10(-8)) is present in all samples; Helium isotopic composition suggests that its origin is uniform,crustal (radiogenic) and, probably, connected with mud volcano gases. Apparently deep helium is residual gas that remains in isolated volumes after hydrate formation. Measured helium content in hydrate gases is very low: 0.5-10 ppm. but in one particular sample it is very high: 7080 ppm.
