Entering Shitang Forest, like entering the natural and complete volcanic rock geological museum, here are the geological relics formed by multiple volcanic eruptions in history, the magma of the volcanic eruption covers the ground to form a broad lava mat, lava quilt, etc., lava above the ground often form platforms. The vast lava platform in Aershan, which covers an area of 1,000 square kilometers, of which the most spectacular is the formation of the Daheigou area of 20 kilometers long, Shitang Forest Shitang Forest 10 kilometers wide Shitang landform, known as "Daheigou basalt", lithological alkaline basalt and olive basalt. The rock pond is like a rough lava ocean, forming a variety of lava forms, including flip floral stones, lava fins, lava ropes, lava dishes, lava caves, lava hills, jet cones, lava valleys, underground dark rivers and other magical landscapes. Melt is also found in large areas of volcanic lava landforms The rock turtle back structure, according to geologists, is the only large-scale, well-developed and well-preserved lava back structure in China. In addition, there are hundreds of lava hills, which is the only basalt geomorphology that can be seen here in the country at present. This lava hill is mostly in the shape of a hoe, with a diameter of 5-7 meters and a height of 2-4 meters. There is a venting hole in the middle, which makes the top and side of the lava hill often crack, forming a cracked hole. Deep-source inclusions - Erhui olive and olive, garnet, etc. are also found in basalt. These are of great scientific value to the tectonic environment in the deep crust. In the stone pond where there is no accumulation of soil, there are tall and upright larchs, large swaths of cypress, pine, Venus plum, Yinxing plum and other plants. In the stone pond forest, the strange stones of the earth are dependent on the trees and the flowers and plants are blended. Clear stone stream, quiet water pools are now and then, jumping stone rabbits sometimes make a crisp sound, forming a wonderful spectacular, lively and clever stone forest painting.
