Textural relationships between the vein minerals suggest that arsenopyrite, K-feldspar, quartz, and muscovite formed in one paragenetic stage. Native gold, native bismuth, scorodite, and galena were introduced in a later paragenetic stage. The isochron derived from K-feldspar and muscovite occurring in the veins yielded In situ Rb-Sr dating of the same assemblage K-feldspar and muscovite in the host rock gave an isochron age of Biotite from the host rock gave an isochron age of The age of vein formation was successfully distinguished from the age of the Alpine-Himalayan orogenic event associated with main Menderes metamorphism. This study demonstrates that in situ Rb-Sr isotopic study can be applied to resolve absolute dating of orogenic deposits in metamorphic complexes.

Six orthogneisses near Mellid have an isochron age of ± 24 Ma with initial. We have combined precise in situ Pb-Pb dates with Pb-Pb isochron dating to constrain the early history of the Apollo 17 granulite The rock contains. In situ Rb-Sr dating of the same assemblage (K-feldspar and muscovite) in the host rock gave an isochron age of ± Ma, 10 Ma older than.Recent studies have shown that Zr minerals and Ca phosphates in petrographically, chemically, and microstructurally well-characterized lunar impactites can yield easily reproducible U-Pb ages that can be related to impacts. This reflects strong REE fractionation in the pegmatite garnet, which, together with the inclusion-free nature of the crystal, points to the high suitability of such garnets for Sm-Nd dating.

German Title: Uranreihen-Datierung diagenetisch veränderter fossiler Riffkorallen und die Anwendung zur Meeresspiegelrekonstruktion. To address this debate, we determined rock uplift in South Africa from the long-term incision rate of the Sundays River, near Port Elizabeth, and from an uplifted marine terrace near Durban.
