Also, substances with a higher melting point will tend to crystallize out at the top of a magma chamber and fall, since it will be cooler at the top. The solubility of various substances in the magma also could be a function of temperature, and have an influence on the composition of the magma at the top and bottom of the magma chamber. An extraterrestrial impact. So all of the scenarios given before can also yield spurious isochrons. The mineral makeup of an igneous rock is ultimately determined by the chemical composition of the magma from which it crystallized. Many more, plus a discussion of the different types of meteorites and their origins, can be found in Dalrymple Progressive geochemical differentiation of the upper mantle of the Earth has resulted in the concentration of U and Th into the rocks of the continental crust compared to those of the upper mantle.

But it could be measuring the apparent age of the ocean floor or crustal material rather than the time of the lava flow.

Which of the following is not a mineral? Mantle material is very low in uranium and thorium, having only 0. The idea of isochrons is that one has a parent element, P, a daughter element, D, and another isotope, N, of the daughter that is not generated by decay.
