Quartz var: Chalcedony
Formula: SiO2
Reference: Richard De Nul collection
Quartz var: Jasper
Colour: brown-red
Description: Most of the quartz cavities with goethite sprays are found in "jasper" boulders. Peter Haas wrote on this subject : The mere fact that the locals call it "jasper" doesn't make it real jasper. It's the material that is referred to by Dines (more correctly) as "siliceous ironstone". At a microscopic scale, it consists of separate iron oxide and silica (quartz or chalcedony) particles, while true jasper is a mass of chalcedony, in which iron oxides are finely dispersed (hence the lighter and redder colour). At a scale where you can easily see the inhomogeneity of the ironstone, jasper is still apparently homogeneous. As you correctly say in the caption, this is a rock, while jasper is still a mineral. While there also is true jasper occurring at Botallack, it only sparingly occurs in the mines, whereas the ironstone is utterly abundant.
