Rock (geology) - Wikipedia

Rocks are composed primarily of grains of minerals, which are crystalline solids formed from a chemical compound arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. Some rocks also contain mineraloids, which are rigid, mineral-like substances, such as volcanic glass, that lacks crystalline structure. The types and abundance of minerals in a rock are determined by the manner in which it was formed.

As the Triassic and Jurassic sediments in these basins were buried, compacted and heated over time, some of the water in the rock was forced out, along with any dissolved metals and migrated into the neighbouring Carboniferous Limestone. Here the change in chemistry, temperature and pressure led to the deposition of various minerals including lead, zinc, and locally copper.
