What is the function of pebbles?

1. Architecture

Pebbles are widely used in public buildings, villas, courtyard buildings, paving roads (cobblestone roads paved in parks have the effect of prolonging life), park rockeries, bonsai filling materials, garden art and other advanced superstructure. It not only carries forward the ancient culture of the East, but also embodies the classical, elegant and original artistic style of the West.

2. Garden function

Pebbles also provide high-quality materials for water purification, sewage treatment, electric power, gardens and other projects. It also provides raw and auxiliary materials for ceramics, precision casting, paper making, jet milling, chemical industry, monocrystalline silicon and national defense.

3. Health Benefits

According to the Associated Press, cobblestone paths are more beneficial to your health and can lower your blood pressure. According to the latest research results of Oregon Research Institute in the United States, people over the age of 6 walk on the smooth cobblestone path for half an hour every day, and after four months of continuous walking, their hypertension will be significantly reduced, and their physical balance and coordination will also be significantly improved.

Extended information:

1. The formation process

can be river scouring or mutual friction. Pebbles may be caused by floods and mudslides in history (because they are generally in mountainous areas), but the specific reasons depend on the geological structure and geographical environment there, and also need to refer to the situation of other surrounding mountains.

about 1 million years ago, in the Mesozoic era, under the action of crustal movement, magma emerged from the surface, and the rapidly cooled magma formed granite.

Since then, thousands of years ago, due to the dislocation and extrusion of granite caused by magma intrusion, a large number of small stones have been produced. Those stones near the water, after a long period of slow water erosion and mutual rolling, finally formed today's pebbles. Some of them are rounded and become pebbles after weathering.

II. Distribution

The main producing areas of rain flower stones in China come from Nanjing and Jiangsu, and the middle and lower reaches of the Yangtze River are rich in resources, which are mostly sedimentary.

in addition, other areas are also rich in pebble resources, including Shandong and Liaoning in the north and Guizhou, Chongqing and Guangxi in the south, all of which have their own characteristics and are rich in variety.

Among them, due to historical reasons, pebble resources in Guizhou and Guangxi are well preserved and rich in species.

there are many large pebbles in southwest China, which are large in size and strange in shape, and are especially suitable for being used as geomantic stones or cultural stones of landmark buildings.
