How did Kunming Stone Forest come into being?

Kunming Shilin Scenic Area (also known as Yunnan Shilin) is formed under favorable geological, climatic and hydrological conditions, where soluble rock-carbonate rock is cut by more than two groups of vertical cracks, and then dissolved by water and organisms along the cracks, and the stone pillars are separated with the deepening and widening of karst ditches.

Shilin is a masterpiece of the earth's evolution, and its formation has gone through a long and complicated geological evolution process. At first, limestone was formed in the sea. Later, due to crustal changes, the sea became land, the flat land became mountains, and limestone was strangely shaped into a stone forest landform. Shilin landform is also in the evolution of inheritance, replacement and superposition. The old stone forest gradually disappears, and new stone forests are constantly formed. ?

Topography of Stone Forest in Yunnan Province

The main type of geological relics in Yunnan Shilin is karst geology and geomorphology.

1. Shilin can be distributed in karst hills, depressions, lakes, rivers, waterfalls, caves and other karst landforms, which enriches the types and scientific significance of Shilin. The combination of stone forest and distributed landform is called stone forest combination landform. The main distribution types are: Shilin depression, Shilin valley, Shilin ridge, Shilin slope, Shilin basin, Shilin karst hills, and Jianfeng karst castle.

2. There are more than 30 kinds of surface corrosion patterns, mainly including various corrosion grooves, corrosion disks, corrosion lines, corrosion cavities, corrosion surfaces under the soil, corrosion lateral grooves, well-shaped corrosion grooves, corrosion scallops, peak corrosion marks, underground river pipeline residues, red algae marks, gravity collapse groove marks and so on. , decorated with stone pillars. It not only enriches the ornamental value of Shilin, but also provides a scientific basis for studying its formation and evolution.
