What is one reason why radiometric dating of metamorphic rocks is rarely accurate -

For example, a method based on a parent isotope with a very long half-life, such as Sm, is not very useful for measuring the age of a rock only a few million years old because insufficient amounts of the daughter isotope accumulate in this short time. On Earth, less than 5 percent of the lithosphere consists of sedimentary rocks, and yet they cover 75 percent of the exposed land masses. Lesser Laramide uplifts dot Wyoming. What is metamorphic rock use in a sentence? Suspiciously, the Laramide Orogeny took off just as arc magmatism related to the Farallon plate snuffed out. It is based on the radioactivity of 40 K, which undergoes dual decay by electron capture to 40 Ar and by beta emission to 40 Ca. Evaporites may be important types of rocks or intergranular cements on Mars, as they are in terrestrial deserts. Because they are hard and waterproof. The K-Ar ages on rocks and minerals from this area in southwestern Minnesota also record this 1.

One magma batch had rubidium and strontium compositions near the upper end of a line such as in Fig. Modern mammal and bird families become recognizable. Near Earth's surface, the atmosphere contains about atoms in the same volume.
