Black Country Bricks

Black Country geology is often celebrated for those three things that were so crucial to the industrial revolution: Coal, limestone and iron ore, but there is another rock which is often forgotten: Clay.

It reveals that even minerals can have a sense of humour at this festive time of year. Petrology deals with the origin, composition, structure, and alteration of rocks. To do this geologists slice up perfectly good [...]

Minerals are often single crystals with a particular [...]

Minerals

A mineral is a solid naturally occurring substance with a crystalline structure and a composition specific to that mineral.  It has an atomic arrangement specific to its mineral variety.  On a whole, they are inorganic elements or compounds which form through a process known as crystallisation. An example of minerals crystallising are those within a [...]
