Wonderful stone

There are many wonderful stones in the world. Below, I will introduce you to several stones!

In the beautiful places and small streams, there are neat polygon patterns on the boulder, which is the turtle stone. The tortoise stone is formed by hundreds of years of mountain changes, and the stone contains a lot of minerals. On many levees, you can see a neat and smooth turtle stone.

In the cave where you can't see your fingers, there are colorful, odd-shaped stalactites. The stalactites are formed by water droplets. The stones were originally rough and later discovered as tourist attractions. As each visitor curiously touched it, the stone gradually became smooth. There is also an alias for stalactites called "stalactites."

In the beautiful Dali, there is a kind of strange stone, its name is "marble". Marble is a metamorphic rock composed of granular calcite and dolomite, usually white or with black, gray, brown patterns, very shiny. It is mostly used for making ornaments and carvings, building materials, and is an indispensable stone in life.
