Rockfest: Rock Walk

November 16, 2018 @ 3:00 pm - 5:00 pm

Announcement of an open-air Rockfest (‘Rock Walk’), November 16, 2018

Near the Earth Sciences Centre, city and university roads are decorated with rows of angular blocks and well-rounded glacial boulders, exhibiting mineralogical, petrological and structural features worth examining by geoscience students.

Weather permitting, the participants in the upcoming Rockfest will go on a guided tour, featuring several blocks and boulders along the west side of Huron Street, in front of the Department of Earth Sciences, and along Willcocks Street, between Huron and St. George Streets. Professors Gregory, Chu, Robin and Schwerdtner will act as scientific guides.

All participants in the Rock Walk should meet at 3:00 p.m. in Room ES2093, so that the Rock Walk can start at 3:10 p.m. It will end around 3:50 p.m. and be followed by a brief discussion period in Room ES2093, in which the guides will try answering questions about the geology of decorative blocks examined or related general problems of geoscience. In case of very poor weather conditions on November 16, the Rock Walk will be postponed to a suitable date in 2019. As substitute for the postponed Rock Walk, Professor Xu Chu will then give an illustrated oral presentation about his recent work on the geology of northwest China.

To avoid undesirable crowding at individual small- to mid-size blocks and glacial boulders, especially those at the north side of Willcocks Street, the Rockfest crowd will be divided into a ‘Grenville group’ and a ‘general earth-sciences group’ led, respectively, by Fried Schwerdtner and Pierre Robin. Professors Xu Chu (petrology) and Daniel Gregory (economic geology) served as associate guides during the 2018 Graduate Field Trip and will, therefore, act as co-leaders during the Rock Walk. The ‘Grenville group’ will include graduate students who participated in the 2018 Graduate Field Trip or whose current thesis projects address mineralogical or petrological problems involving igneous or metamorphic rocks. Additionally, the Grenville group will include professional geologists and faculty members interested in the geology and rock assemblages of the Grenville Province (Ontario).

Main objectives of the Walk (Grenville part): As during the 2018 Graduate Field Trip to the Bracebridge-Burk’s Falls-Huntsville region, special emphasis will be placed on field criteria whereby one may distinguish between plutonic and metaplutonic rocks. As on the field trip, early- to late-orogenic granite pegmatite will be highlighted during the Rock Walk (Grenville part). Its participants will be encouraged to (1) inspect coarse-grained mineral assemblages with the naked eye or a hand lens and (2) observe textural and structural features widely used in the field to distinguish plutonic rocks from their metamorphic counterparts.
