This field trip is primarily aimed at beginners, amateurs and others who might not have encountered granite before or the geology of South Dublin(/North Wicklow). It might serve as an introduction to Peadar McArdle’s field trip to the Blackstairs granite this coming May. My trip will visit just two locations to examine the basics of what granite is, the rocks that are associated with granite proper (aplites, pegmatites, quartz veins), and a local sample of a rock type that the Leinster granite itself intrudes (andalusite schist). By good fortune, both stops are ‘beauty spots’, so if the weather is kind, everyone should bring their cameras. Both locations require only short walks on paved paths. However, the paths are somewhat steepish in parts. Bring appropriate footwear and wet weather gear, just in case. Finally, because parking at the first stop in Killiney can be quite problematic at weekends, I am starting the field trip at the early time of 9:30 am. Other than that, the day’s timings will be relatively relaxed. Anyway, the first stop at White Rock can quickly fill up with nudists, and we want to get there first!
