Bennachie Wildlife Group - Geology Day: Saturday 20th July

10:00 20 July 2019

A day to make people become more familiar with the processes that have generated the many granite intrusions of the North-East, there will be an introductory talk and field visits. Booking essential.

Details

To take part in the Geology walk please book by emailing: wildlife.bennachie@btinternet.com. The day will start at 10:00 at Monymusk Village Hall for an introductory talk. Car shares can be arranged at Monymusk for field visits. Please wear appropriate clothing and bring your own refreshments (tea and coffee will be made at the hall). The field visits will include short walks but nothing too strenuous. Peter Craig, the tutor, has very kindly organised some excellent field visits for us. He has provided the following information. The main aim of the day will be to become more familiar with the processes that have generated the many granite intrusions of the North-East, including those that have acted to reveal them as we see them in today's landscape. Bennachie has many magnificent (and presumably very familiar) granite outcrops - but what might we see if we were able to see into the heart of the hill? After an introductory presentation at Monymusk outlining the geological background, the group will visit Corrennie Quarry where we will get that chance to see right inside a hill of granite, and wonder at some of the complex internal relationships that are not usually apparent in weathered surface outcrops. Breedon Aggregates have generously offered an escort to ensure safe and easy access to the features in this quarry. We will then drive another ten miles to a very different granite quarry at Mill Maud, near the Crossroads of Lumphanan. There are answers here, some quite surprising, to some of the questions that are often asked about the age of our local landscape features and about the processes that created them. The excursion will be concluded at this quarry.
