Joaquin Ruiz, Lois M. Jones, William C. Kelly; Rubidium-strontium dating of ore deposits hosted by Rb-rich rocks, using calcite and other common Sr-bearing minerals. Geology ; 12 5 : — We have tested a Rb-Sr technique that permits ore deposits to be dated using common gangue minerals such as calcite and fluorite. The technique was tested using fluorite and calcite from three deposits ranging in age from Tertiary to Precambrian. In all cases the age determined here closely resembles that obtained by conventional K-Ar and Rb-Sr dating methods. Shibboleth Sign In. OpenAthens Sign In. Institutional Sign In.
Ruiz , L. Jones, W. Describes a Rb-Sr technique that permits ore deposits to be dated using common gangue minerals such as calcite and fluorite. The technique was tested using fluorite and calcite from three deposits ranging in age from Tertiary to Precambrian.
The rubidium-strontium dating method is a radiometric dating technique used by scientists to determine the age of rocks and minerals from the quantities they contain of specific isotopes of rubidium and strontium.
Read the full text on a web page. The Rb-Sr beta-decay dating system is one of the most attractive tools in geochronology, as Rb is sufficiently abundant in common K-bearing minerals like biotite, muscovite and K-feldspar. This allows dating of a wide variety of rocks e. However, this advantage was to date negatively counteracted by the lack of a suitable in-situ technique, as beta decay systems by nature have isobaric interferences of the daughter isotope by their respective parent isotope.
advantages and disadvantages in bold are) o Rubidium – Strontium dating 87 Rb decays to 87 Sr with t 1/2 = x 10 10 years Normalize to.
The secret things belong unto the Lord our God: but those things which are revealed belong unto us and to our children forever, that we may do the words of this law. Deuteronomy Most readers appreciate the hard science, but many have struggled with the equations. The purpose of this series is to demonstrate in no uncertain terms that these dating methods do not prove that Earth is millions or billions of years old, as is often reported.
To provide context for Part 4, below is a summary of the first three articles—all are available online. Part 1: Clocks in Rocks?

The Rubidum-Strontium dating method, is one of the ways that geologists determine the age of rocks[? For example, consider the case of a simple igneous rock such as a granite that contains several major Sr-bearing minerals including plagioclase feldspar , K-feldspar, hornblende , biotite , and muscovite. If these minerals crystallized[?
A rubidium/strontium three-isotope plot (see following figure) is constructed involving If they are not used for dating the rock, the points represented by these.
Rubidium-strontium dating , method of estimating the age of rocks, minerals, and meteorites from measurements of the amount of the stable isotope strontium formed by the decay of the unstable isotope rubidium that was present in the rock at the time of its formation. Rubidium comprises The method is applicable to very old rocks because the transformation is extremely slow: the half-life, or time required for half the initial quantity of rubidium to disappear, is approximately 50 billion years.
Most minerals that contain rubidium also have some strontium incorporated when the mineral was formed, so a correction must be made for this initial amount of strontium to obtain the radiogenic increment i.

Is Earth young or old? If old, did that mean the Bible is wrong? Or could science be wrong? And what is she going to tell her son? Scientists agree that radiometric-dating techniques offer the most concrete evidence of any dating system for answering questions about the age of Earth.
