WebAssumptions for U-Th Dating: Open vs. Closed Systems. Uranium-Thorium (U-Th) dating is a common method used to date calcium carbonate (CaCO 3) bearing samples, including speleothems, corals, shells and in some cases bones.. This method assumes that the sample in question does not exchange thorium (230 Th) or uranium (238 U) with the … WebThorium is fertile rather than fissile, whereas uranium is both fertile and fissile. What this means is that when an isotope is fertile it is likely to absorb the neutrons that it is bombarded with in order to convert into another element, which is more likely to be fizzle. A fizzle element is one whose nucleus is likely to split into two ...
