To answer this question, first figure out what you know. (i.e. you know 87Sr The paper reports Rb-Sr isotopic data obtained by the authors on ore-hosting rocks from the Kairagach epithermal Au-Ag deposit in the Kurama ore district in the Central Tien Shan, Uzbekistan. The influence of mineralizing hydrothermal solutions on 2001-12-01 Aug. 2014 DUAN Ruichun, YANG Hongmei, LIU Chongpeng, ZHANG Liguo, LING Wenli, CHEN Wen and TONG Xirun, 2014.

The Decay Equation Rocks that contain 87 Rb also contain initial amounts of 87 Sr, so when comparing the relative amounts of 87 Rb and 87 Sr, the amount of 87 Sr present initially must be accounted for. Also, a certain amount of 86 Sr is present that is not a product of Rb decay, this is stable. Age of granite rocks can be determined using Rb - Sr whole rock radioactive dating method and the following age equation, (87Sr/86Sr) = (87Sr/86Sr), + (87Rb/86Sr) (ell - 1) For a suite of representative co-magmatic granitic rocks, the Rb - Sr whole rock isochron plot and relevant data are shown in the diagram. Rb^87 - Sr^87 decay equation used to calculate the dating is: Sr^87/Sr^86 = (Sr^87/Sr^86)_i + Rb^87/Sr^86(e^lambda t - 1) equation where view the full answer Dating Rocks with the Rb-Sr "Isochron" Method There are numerous radioactive isotopes that can be used for numeric dating.
An associated optimal sampling technique would involve using single grain etching. 2020-01-17 Age of granite rocks can be determined using Rb - Sr whole rock radioactive dating method and the following age equation, (87Sr/86Sr) = (87Sr/86Sr), + (87Rb/86Sr) (ell - 1) For a suite of representative co-magmatic granitic rocks, the Rb - Sr whole rock isochron plot and relevant data are shown in the diagram. For the Rb-Sr system, λ = 1.42 x10-5.

Generalmente, la relación Rb/Sr aumenta en el orden plagioclasa, hornblenda, feldespatos de potasio, biotita, moscovita. Por lo tanto, dado el tiempo suficiente para la producción significativa (crecimiento interno) de 87 Sr radiogénico , medidos los valores 87 Sr / 86 Sr serán diferentes en los minerales, aumentando en el mismo orden.
