WebAn atom of an element with a different number of neutrons is an isotope of that element. For example, the isotope carbon-12 contains 6 neutrons in its nucleus, while the isotope carbon-13 has 7 neutrons. Some isotopes are radioactive, which means they are unstable and likely to decay. Web87 Sr 86 Sr ratios, trace element and REE compositions, and textural characteristics were determined for three hydrogenetic Fe-Mn crusts, one hydrothermal deposit, and two mixed hydrothermalhydrogenetic crusts from the Pacific. The Sr isotope data are compared to the Sr seawater curve for the Cenozoic to determine the ages and growth rates of the crusts.
