Rare element pegmatite fields host critical elements that are crucial for the high-tech industry (Li, Nb,
Ta, etc.). In contrast to the traditional genetic model involving large parental fertile granites, recent
studies suggest that such pegmatite fields can directly derive from anatectic melts. The offered one day
field trip to the St. Radegund area (Styria, Austria) will target one such field, where migmatites,
simple pegmatites, leucogranites and spodumene pegmatites are exposed within the Austroalpine
Unit (Eastern Alps). 8 key outcrops will be visited along a profile through the pegmatite field, providing
an exceptional insight into the genetic relationships between migmatites and spodumene pegmatites.
The field observations will be discussed together with geochemical and geochronological data acquired
on the visited outcrops and the surrounding area. (https://sites.google.com/site/alexisplunder/egu2019)

A field trip guide will be given to the participants. The bus trip from Vienna to St. Radegund will take
approximately 2 hours. Additional geological information will be provided during this time. The field
trip includes a 3 hours walk on good hiking trails.

The field trip is organized by the Geological Survey of Austria and the University of Leoben.
