AT the estimated 2 × 1020 gm. uranium and 5 × 1020 gm. thorium in the lithosphere, helium should be generated radiogenically at a rate of about 3 × 109 gm./year. Moreover, the (secondary) cosmic-ray source of helium has been estimated to be of comparable magnitude. Apparently nearly all the helium from sedimentary rocks and, according to Keevil1 and Hurley2, about 0.8 of the radiogenic helium from igneous rocks, have been released into the atmosphere during geological times (currently taken to…
Helium Diffusion Rates Support Accelerated Nuclear Decay
• Geology

Two decades ago, Robert Gentry and his colleagues at Oak Ridge National Laboratory reported surprisingly high amounts of nuclear-decay-generated helium in tiny radioactive zircons recovered from
The Age of the Earth's Atmosphere Estimated by its Helium Content
If the earth is billions of years old, the radioactive production of helium in the earth’s crust should have added a large quantity of helium to its atmosphere. Current diffusion models all indicate
Catastrophic Plate Tectonics: The Physics Behind the Genesis Flood

The wealth of new data, mostly from the ocean bottom, that precipitated the acceptance of plate tectonics during the 1960’s simultaneously also opened the door for the first time in more than 200

Granulated samples of acidic igneous rocks have been found to give a much higher rate of emission of alpha particles than corresponds to the known total contents of uranium and thorium. Abnormally
Helium retentivities of minerals
The retentive properties for helium of various minerals are of both mineralogical and geological importance. Since the degree of retention of helium is generally appreciable and helium is present in

The isotopic abundance of ${\mathrm{He}}^{3}$ in one sample each of "well" helium and "atmospheric" helium has been measured by detecting the ${\mathrm{He}}^{3}(n,p){\mathrm{H}}^{3}$ disintegrations
