Black pebbles

Black cobblestone, as a pure natural stone, is taken from the sand and stone mountains produced by the ancient river bed after the crustal movement of thousands of years ago. It has experienced the impact of mountain torrents and continuous extrusion and friction during the process of running water. In the course of the evolution of the vicissitudes of thousands of years, the movement of their waves and punching water has lost the irregularities of the rubbing and rubbing of gravel, and silenced in the underground for millions of years. The main chemical composition of pebble is silica, followed by a small amount of iron oxide and trace elements such as manganese, copper, aluminum, magnesium and other compounds. They have different pigments, such as red red for iron, blue for copper, purple for manganese, yellow semitransparent as silica gel pulp, jadeite color containing green minerals and so on. So that pebbles appear black, white, yellow, red, dark green, gray and so on.

On the distribution of pebbles:
The main black cobblestone origin in China is from the Lingshou area of Hebei. The front area of the Taihang Mountains is rich in resources and most of them are deposited. In addition, the pebble resources in the rest of the region are also rich, and the pebble resources in the North including Shijiazhuang and Lingshou have their own characteristics, and the species are rich and rich in variety. Among them, Shijiazhuang and Lingshou's Pebble resources are relatively well preserved because of historical reasons. There are many large pebbles in the southwest, which are large and odd in shape. They are especially suitable for geomantic stones or cultural stones of landmark buildings.
