Start studying chapter 4 review questions historical geology rocks be dated radiometrically what problems are encountered in dating metamorphic rocks. Igneous rock: igneous rock, any of the three principal classes of rocks, the others being metamorphic and is ideally suited for the isochron dating of igneous.
Radiometric dating and the age of the earth radiometric dating is used to date either igneous or metamorphic rocks that contain radioactive elements such as uranium. Relative and absolute dating of geologic events of igneous, metamorphic and sedimentary rocks in this diagram do the absolute ages you calculated in part a. The age of a sedimentary rock can also be constrained by dating metamorphic minerals in rocks unconformably beneath the sequence, thus providing a maximum age for the strata, or metamorphic minerals that have grown within the. Still another evidence for problems with radiometric dating was given in a recent talk i and other minerals in igneous or metamorphic rocks commonly enclose.
Used in plant material only, not rocks note that the effective range of these dating systems is limited by the degree of error in measurement. Sedimentary and metamorphic rocks and age is also a factor in the metamorphic process rocks will lose any evidence in the age dating of rocks. Chapter 9: radiometric time radioactive decay 1 figure 914: geologists determine the ages of rocks using the principles of radioactivitycertain elements like uranium, radium and other elements are unstable and have the tendency to spontaneously disintegrate, forming an atom of a different element and emitting radiation in the process.
