U/Pb whole-rock and mineral dating of the Falkenberg granite in. An age of 316 ± 9 Ma was calculated from a Pb—Pb isochron for these samples. U/Pb and Pb/Pb isotope ratios of 10 whole-rock samples, 3 K-feldspars, 3 muscovites, 3 biotites, and 7 apatites from the Falkenberg granite northeast Bavaria.
Isochron Dating - Talk Orins U/Pb and Pb/Pb isotope ratios of 10 whole-rock samples, 3 K-feldspars, 3 muscovites, 3 biotites, and 7 apatites from the Falkenberg granite (northeast Bavaria) define a three-dimensional discordia plane yielding intersection ages of. A brief introduction to isochron dating methodology. snificant scatter into the isochron plot if any measure other than whole-rock is made.
K-Ar dating, whole-rock and Sr-Nd isotope geochemistry of calc. However, dates derived from zircons scatter between 320 and 360 Ma. The K-Ar whole-rock dating of these rocks range from 37.62 ± 3.33 Ma Middle Eocene to 30.02 ± 2.84 Ma Early Olocene for the andesitic.
Metamorphic rocks - On a Faraway Day For the least deformed, folded but not schistose, fossiliferous Lower Ordovician sediments (zone A), a scatter of the data points resulted, at least partly due to the varying amount of detrital muscovites, which did not equilibrate their Sr isotopes with those of the clay minerals. Dating metamorphic rocks. 3.3.1 Open mineral systems. Mineral and whole-rock RbSr systems may respond differently to metamorphic events.
Generation and distortion of Rb/Sr whole-rock isochrons - effects of. Fossiliferous Middle Cambrian sediments (zone B), however, are colinear in an isochron plot. For precise dating the boundary conditions of the Rb/Sr whole-rock dating. Rb/Sr dating, whole-rock isochrons, metamorphism, hydrothermal alteration.
LA-ICP MS zircon dating, whole-rock and Sr–Nd–Pb–O isotope. The rocks are also folded, and show a beginning schistosity in the pelitic layers. therefore does not correspond to the time of sedimentation, as one would expect from most of the interpretations given in the literature. LA-ICP MS zircon dating, whole-rock and Sr–Nd–Pb–O isotope geochemistry of the Camiboğazı pluton, Eastern Pontides, NE Turkey Implications for.
