The Tourmaline 2017 post-conference field trip focused at tourmaline variability in diverse geological systems. The conference venue was very suitable for the purpose, as it is very close to the eastern border of the Variscan orogene and the front of the Moldanubian thrust.

The field trip program was:

Day 1 (June 26)	Theme: Tourmalines from metacarbonates and associated calc-silicate rocks from the easternmost boundary of the Variscan orogene Visited locality: Trhonice
	Theme: Tourmaline in tourmalinites from mica-schists of the Svratka Unit Visited locality:  Ujčov
	Theme: Orthogneiss with F-rich tourmalines Visited locality: Nedvědice
	Theme: Distinct compositional  evolution of tourmaline in LCT pegmatites Visited locality: Rožná-Hradisko (type locality of rossmanite)
	Night: Skalský dvůr
Day 2 (June 27)	Theme: Tourmalines and anhydrous B-silicates related to anatectic processes in granulites and migmatites Visited locality: Horní Bory
	Theme: Tourmalines from NYF pegmatites of the Třebíč Pluton Visited locality: Oslavice
	Theme: Orbicular-tourmaline in leucogranites Visited locality: Lavičky
	Night: Kutná Hora
Day 3 (June 28)	Theme: Tourmaline granite – pegmatite – orthogneiss complex Visited locality: Přibyslavice (type locality of oxy-schorl)
	Theme (skipped):  Anatectic metapegmatites with tourmaline and dumortierite Locality: Starkoč
