WHERE: Old Mine Park and vicinity in northern Trumbull.
WHEN: POSTPONED
LEADERS: Harold Moritz, Bill Devlin, and Robert Wintsch
This year's trip will focus exclusively on the geology, mineralogy and mining history of Old Mine Park and vicinity in northern Trumbull.
Your trip leaders will spend the day presenting the varied aspects of this unique area, including information on new, detailed geologic mapping, petrologic and stratigraphic studies, radiometric dating, and tectonic structure. The mineralogy includes amphibolite-hosted scheelite (and localized ferberite pseudomorphing and tungstite alteration); metasomatic alteration of the amphibolite; enigmatic cross-cutting hydrothermal (or pegmatitic?) muscovite-quartz, albite or calcite-rich veins hosting fluorite, topaz (with local margarite pseudomorphing), chlorite and rarely beryl (emerald?); and brittle-fault-hosted quartz-calcite-fluorite-sulfide veins. The known or potential relationships between the geology and the mineralogy will be explored at mining locations old and new. A guide book will be included.
The trip will be limited to 60 GSC members.
COST: Student member ($25), Regular Member ($50), Non-Member ($70)
