Participants in Geology 2 were enjoying a varied programme during 2019-2020 prior to the curtailment of plans due to the Coronavirus outbreak. The session began in September, at the new venue in Glasgow Road, with a review of summer 2019 visits. Preferences were sought and a syllabus for the winter was drawn up.
Minerals and Health was the subject chosen for the October meeting. Ian gave an informative talk on health hazards caused by respirable and carcinogenic minerals and encouraged interactive discussion thereafter. ‘Edible Geology’ was rocky cakes!
In November, members prepared a short presentation. Topics included: salt deposits, Isle of Wight cliff exposures, cobalt-rich seabed nodules and Jordanian sandstone. Edible geology was Toffee Crisp conglomerate!
Simple mineral identification was explained clearly and professionally by Ray in December. Location, radioactivity, colour, lustre, hardness, cleavage/fracture and specific gravity were covered; samples were examined and discussion abounded. Explanation of the White Island, New Zealand volcanic eruption was an impromptu extra with pictures and accounts from members who had previously visited the site.
Chile was the location for the main presentation in January. Peter described the mountain structure in the Torres Del Paine National Park and explained the accretion of limestone by thrombolites in a freshwater environment. A quick explanation of Lewisian Gneiss was given by Ann and chocolate flakes showed metamorphic folding.
The complexities of Mineral Classification were introduced by Ray in February. Classification Guides and chemical structures were explained. Some time was given to discussing a planned field visit. Crème Eggs illustrated the structure of the earth!
A session on maps, a field visit to Arthur’s Seat with Angus Miller and a weekend trip to the North West Geopark at Ullapool were all postponed.
Sixteen members were enrolled and the average attendance over the session was 75%.
