Calling all rockhounds…Here’s Nightjar with the exciting next chapter in her series.
Chapter 8 – West Hill: Phyllite rocks!
It’s not only the vegetation that is different here, the rocks are very different too. We left sedimentary rocks behind and we are now in the domain of metamorphic rocks. Mostly phyllites. Phyllite is a metamorphic rock originating from shale sediments, it’s soft and highly foliated, easy to split into sheets, and it smells of clay. The most wonderful characteristics? The colours and the sheen! You can’t mistake that sheen for anything else. Phyllites here are really pretty.
These rocks are much older than the Jurassic limestones of the East Hill, dating from the Proterozoic. We won’t find fossils here, but there’s more than just phyllites. Next we will be searching for quartz!
