The chemical and isotopic record of rock-water interaction ...

Chemical, isotopic, radiographic, and rock-leaching data are combined to describe the effects of rock-water interactions in core samples of petrographically fresh, 1.43 b.y.-old Sherman Granite. The data serve to identify sensitive indicators of incipient alteration and to estimate the degree, pathways, and timing of element mobilization. Unfractured core samples of Sherman Granite are ...

More Bad News for Radiometric Dating

Faure shows that in granite U is 4.8 ppm while Pb is 23 ppm, while in andesite U is 2.4 ppm and Pb is 5.8. Some process is causing the differences in the ratios of these magmatic rocks. Depending on their oxidation state, according to Faure, uranium minerals can be very soluble in water while thorium compounds are, generally, very insoluble.

Granite and Radon – Radon

Thorium produces a different type of gas called Thoron. Thorium is a shorter-lived element, which is similar to radon but decays about 6,500 times faster than radon. Thoron has a half-life of about 51 seconds, whereas Radon has a half-life of just over 92 hours.

Natural Radioactivity in the Geologic Environment

 · • Granite forms from the slow cooling of magma deep beneath the Earth''s surface. If the magma erupts onto the surface, it forms either rhyolite lava flows or deposits of ash fall or flow tuffs. Erupted granitic rocks are very fine-grained, and often contain the radioactive elements distributed within very fine volcanic glass particles.

Conway granite

Conway granite is a typically pink (or mesoperthitic) biotite granite. It is amphibole-free and of coarse particle size (with portions of the rock fine-grained or porphyritic).. Conway granite has a relatively high concentration of thorium, at about 56 (±6) ppm; this amount is not enough to make the granite dangerously radioactive, but it is sufficient to make the rock a low-grade (almost ...

Locations of Deposits

Thorium is mined in conjunction with uranium, so much that estimates of reserves for these elements are made based off of uranium content. Thorium is typically found in the minerals thorite, thorianite and monazite however monazite is the only mineral from which Thorium is currently mined. These monazite deposits are found in placer deposits.

Do all granite countertops have radon?

 · Like all rocks, granite may contain naturally-occurring radioactive elements like radium, uranium and thorium. Some pieces of granite may contain more of these elements than others. These radioactive elements are solids, but, over time, they may decay into radon, says the Environmental Protection Agency (EPA).
