Reasons For The Formation Of Granite

Granite and basalt belong to magmatic rocks, but the difference is that during magma eruption, granite is an underground part formed under high pressure, and its texture is much denser than basalt formed after eruption, making it very hard. Mount Huangshan was formed after the underground granite exposed to the surface in the process of crustal deformation. When the granite is exposed to the ground and rising strongly, the flowing water cuts down along the vertical joint fissures to form stone pillars or isolated peaks, which cluster into a peak forest, such as the wonderful brush flowers in Mount Huangshan Mountain. The granite peak forest appears extremely majestic and spectacular. For example, Mount Huangshan has a cutting depth of 500-1000 meters, and there are more than 70 peaks with a height of more than 1000 meters.
When the flowing water rushes down along the nearly vertical shear cracks in the granite body, it forms nearly vertical gullies. The gullies become deeper and deeper, forming two walls sandwiching each other. Looking up, the blue sky looks like a straight line, which is called a straight line of sky. Granite is a insoluble rock, therefore it cannot form the common karst caves in limestone areas. But rainwater washes away along the fractures within the granite body, causing the collapse of the overlying rock blocks and forming irregular pile holes. In addition, in areas where stone egg landforms are developed, the gaps between stone eggs can also form caves. Such as Water Curtain Cave, Lotus Cave and Aoyu Cave in Mount Huangshan Mountain. Since ancient times, many famous mountains have gathered springs, which are important tourist attractions in granite mountainous areas. Such as the hot springs in Mount Huangshan Mountain and Lishan Mountain. Granite generally contains very small amounts of radioactive elements. Therefore, the spring water flowing out of granite generally contains a small amount of radioactive radon gas that is harmful to human health. These springs are drinkable and bathing, and are not only important tourism resources, but also valuable water resources. The granite landforms in China mostly appear in the eastern regions with abundant rainfall, where mountains are high and water is high. Therefore, in mountainous areas with developed or relatively developed granite peak forest landforms, waterfalls generally appear. Such as the herringbone waterfall and Baizhang Spring in Mount Huangshan Mountain.
