The gorse is well and truly out this week.
Two granite blocks (undoubtedly from old mine works, not from prehistoric stone circles!) and the right hand boulder is interesting but I'm not sure what it is, Does anyone know? (Marije, perhaps).
Sight and Sound. Maybe I've linked this before. If so, apologies but I like it.

As you know I'm rather fond of granite in its many manifestations.

I think (after looking at a blown-up image that still is a bit low-res) the boulder on the right is probably a high-grade metamorphic rock.. it looks to have glassy texture, from the style of fracturing and the sheen. Maybe it's silica-rich. The light-colored band across it may be a cross-cutting granitic intrusion, a so-called dike. Why is it dark? Probably iron content. From the minuscule amount I know about Cornwall geology, high-grade metamorphics don't seem unreasonable, and they're often associated with granites.
I''m shooting from the hip, mind you--I'd have to see it up close and personal not to be just waving my arms!
