白云石,即白云质大理岩,常杂有方解石或石英脉、长石脉,由沉积的白云质灰岩经区域变质作用后,矿物成分重结晶形成。色呈纯白,由菱面晶体集合成粒状或块状岩体;表面也有形成钙华的,十分俏丽精致。白云岩因其表面成分不同,易风化部分就逐渐变成了沟纹,而难风化部分别凸出石表,最后就形成了最宜制作水旱盆景和树石盆景的优质石材——白云质龟纹石。它与石灰岩风化形成的龟纹石极为相似,但质地更为硬实、纹理更为漂亮。白云岩在安徽肥东、宿县、滁州及大别山区均有大量分布。
Dolomite, the dolomitic marble, is often mixed with calcite or quartz veins and feldspar veins. After the deposited dolomitic limestone undergoes regional metamorphism, the mineral components recrystallize. The color is pure white, and the rhombohedral crystals are aggregated into granular or massive rock masses; the surface also forms travertine, which is very pretty and delicate. Due to the different surface composition of dolomite, the easily weathered part gradually becomes a groove pattern, and the hard weathered part protrudes the stone table respectively. Finally, a high-quality stone that is suitable for making bonsai and bonsai bonsai is formed. Stone. It is very similar to the weathered limestone formed by limestone, but its texture is harder and its texture is more beautiful. Dolomite is widely distributed in Feidong, Suxian, Zhangzhou, and Dabie Mountains in Anhui.
