DESCRIPTION: Rubidium-strontium datingmethod 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.Brad Hinburg: Wtf is this?
Brooke Owens: She just needs some cock to choke on
Amy Delgado: This is SO true. We are like that, specially the walking on the side of the road thing. The superstition many of us just make it as a joke, though. But yeah. This is us.
Geenagr: So cute the guy. He's like my Friend Pedro. His voice lol
Brit Ives: That Brazilian Portuguese was very very confusing! I'm Portuguese and I couldn't understand what she was saying. I really don't know how someone can recognize that as Portuguese but.
Oscar Jaimes: The good thing is that while they are judging the girls in the pictures , we are judging them.
Tiago Costa: Maybe I can find someone traditional like that here in the West Hollywood areas but I seriously doubt it with the bullshit Hollywood superficiality going around.
Sudarshan: In Cambodia most women want spend thousands of dollars to bleach their skin white, like pale. Beauty trends in Asian are terrible, and really unnatural. In Asia, pale skin equals beauty and wealth. It's really sad.
Bustavegas: I like the liverpool accent, im midlands cuz im from west midlands XD
Eazy Jay: i don't care how many people you slept with rofl
Cleane Lima: Ouais, on sonne crissment pas sexy.
Katja What: idk it was funny when i saw it
Zaid Ott: If I open my Gryffindor would you Slyther-in
Californyaeh: I love when she said a bunch of youtubers came forward and she showed their faces and I didnt know any of them

The method is applicable to very old rocks because the transformation is extremely slow: Most minerals that contain Aprisa sr radiometric dating 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.

Rubidium-strontium dating Written By: The Editors of Encyclopaedia Britannica. Learn More in these related Britannica articles: The radioactive decay of rubidium 87 Rb to strontium 87 Sr was the first widely used dating system that utilized the isochron method.
Rubidium—strontium Rb—Sr dating was the first technique in which the whole rock isochron method was extensively employed. Certain rocks that cooled quickly at the surface were found to give precisely defined linear isochrons, but many others did not.
Some studies have shown that rubidium is…. For example, the concentrations of rubidium and the strontium into which it decays, or those of samarium and its decay product neodymium, indicate that the oldest meteorites formed some 4. Other isotope studies demonstrate that Earth formed within, at most, a few tens of millions of years…. Strontium Srchemical element, one of the alkaline-earth metals of Group 2 IIa of the periodic table.
It is used as an ingredient in red signal flares and phosphors and is the principal health hazard in radioactive fallout. Rubidium Rbchemical element of Group 1 Ia in the periodic table, the alkali metal group.
Rubidium is the second most reactive metal and is very Aprisa sr radiometric dating, with a silvery-white lustre. Rubidium was discovered spectroscopically Aprisa sr radiometric dating German scientists Robert Bunsen and Gustav Kirchhoff and named after the two….

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 87 Rb and strontium 87 Sr, 86 Sr. Development of this process was aided by German chemists Otto Hahn and Fritz Strassmann , who later went on to discover nuclear fission in December The utility of the rubidium — strontium isotope system results from the fact that 87 Rb one of two naturally occurring isotopes of rubidium decays to 87 Sr with a half-life of In addition, Rb is a highly incompatible element that, during partial melting of the mantle, prefers to join the magmatic melt rather than remain in mantle minerals.
As a result, Rb is enriched in crustal rocks. The radiogenic daughter, 87 Sr, is produced in this decay process and was produced in rounds of stellar nucleosynthesis predating the creation of the Solar System. During fractional crystallization , Sr tends to become concentrated in plagioclase , leaving Rb in the liquid phase.
Highest ratios 10 or higher occur in pegmatites. For example, consider the case of an igneous rock such as a granite that contains several major Sr-bearing minerals including plagioclase feldspar , K-feldspar , hornblende , biotite , and muscovite. Rubidium substitutes for potassium within the lattice of minerals at a rate proportional to its concentration within the melt. The ideal scenario according to Bowen's reaction series would see a granite melt begin crystallizing a cumulate assemblage of plagioclase and hornblende i.
This then causes orthoclase and biotite, both K rich minerals into which Rb can substitute, to precipitate.
