Mechanized pebble stone is divided into two types: machine polished or artificially bonded. Machine polishing: the corners of the crushed stone are polished into a rounded and smooth form, which is far less smooth than natural cobblestone, and the SiO2 content of natural pebble stone is also higher. Artificial bonding: using micro powder bonding molding, the shape can be controlled at will, the smoothness can be achieved orthodontic spheres, but the compressive strength of the finished product is not as good as natural pebbles.
However, the formation of natural pebbles is a long process. That is, they can be washed by river water, but also by rubbing against each other. The pebbles in your place may be caused by historical floods and mudslides (because it is in a mountainous area) but the exact cause depends on the geological structure there, geography and also needs to refer to other mountains around. As for the mountain that does not grow trees, it may be caused by soil reasons or the connection between surrounding tree species and organisms.
About 100 million years ago, during the Mesozoic Era, magma emerged from the earth's surface under the action of crustal movement, and the rapidly cooled magma formed granite. Since then, thousands of years ago, the intrusion of magma caused granite staggering extrusion, thus producing a large number of smaller stones, those at the water's edge, after a long period of water slowly wash and their own mutual rolling, and finally formed today's pebble stones.
Natural pebble stones are taken from riverbeds, are widely used in public buildings, villas, courtyard buildings, paving, park rockeries, bonsai filling materials, garden art and other high-class superstructures after cleaning, screening and sorting processes. It not only promotes the ancient culture of the East, but also embodies the classical, elegant, and simple art style of the West.
