First in situ Lu–Hf garnet date for a …
In this paper we present the first successful in situ Lu–Hf garnet date of 1801 ± 53 Ma for an LCT pegmatite from the Kietyönmäki deposit in the Somero–Tammela pegmatite region, SW Finland. This age is consistent with previous zircon dates obtained for the region, ranging from 1815 to 1740 Ma with a weighted mean 207Pb / 206Pb age of ...

Hydrogen in spessartine-almandine garnets as a tracer …
2 Introduction Concentrations of Mn and Fe2+ in garnets correlate with the geochemical evolution of zoned pegmatite bodies (Baldwin and Knorring 1983; Whitworth 1992). Specifically, Mn contents increase from the wall zone to the core zone, as Fe2+ decreases. Hydrogen in the form of OH-is also a component of pegmatitic garnets (Aines and Rossman 1984), but no known …

Chemical data indicate that the pegmatite- and aplite-hosted garnets are rich in spessartine and are similar to garnets in many African Li-rich pegmatites. Partial melting as a source of the garnets is unlikely due to the large spessartine component, the abundance of inclusions within the garnets and the general P-T-X evolution of the pegmatite ...

Rough estimates of the bulk composition of the pegmatites could not reveal such a difference. Second, garnet of the Evje–Iveland pegmatites shows a wider range of chemical variability and patterns of Y–HREE zoning compared to the Froland samples. Thus, the gradients of pegmatite fractionation are much stronger within the Evje–Iveland field.
