Noble Gases In The Earth And Its Atmosphere, Robert Anthony Canalas

Masters Theses

"Abundance of noble gases extracted from Fig Tree Shale exhibit a marked deviation from the gas content of eclogitic rocks purported to be mantle material. The abundances of the heavy noble gases in shale were found to exceed the highest known meteoritic values. The abundances of the lighter noble gases were found to be comparable to the abundances of these gases in typical chondrites.

Temperature gradient analyses show that excess heavy gases are released at low temperatures. This is interpreted to indicate a preferential adsorption of the heavy noble gases on fine-grained sediments when these gases were being released from …
