Wuyishan is mainly distributed in metamorphic rock series, volcanic rocks, granite and Mesozoic clastic rocks in pre-Sinian and Sinian.

In the late Mesozoic, a strong volcanic eruption occurred in Wuyishan, followed by a large-scale granite intrusion. It has been found that there are abundant volcanic institutions in this area, which is a typical structural feature of the Pacific Rim region in East Asia. The late Cretaceous red glutenite is the main body of Danxia landform.

1, God bless the peak

Tianyou Peak is 408m above sea level, with a relative height of 2 15m. It is a rock ridge extending from north to south. It is connected with Xianyou Rock in the east and Zhangxianfeng in the west. The cliff is steep and the mountain peaks are towering above Wan Ren. On the peak, there is a stream flowing down the cliff to the bottom of the peak, forming a spring water with a height difference of about 120m. There are many famous and ancient trees on the peak, and the evergreen broad-leaved forest is lush. Xu Xiake, a famous geographer in the Ming Dynasty, praised: "If you can win the Jiuxi River without backing it, this peak should be the first."

There are nearly 100 cliff carvings in the past dynasties on the stone wall next to Humajian at the peak. The largest is the "First Mountain", which was inscribed by Xu Qingchao, general of Dongwu County, Daoguang Renchen. It means that Tianyou Peak is "the first resort in Wuyi" and should be called "the first mountain". It has also been explained that Wuyishan is a famous Taoist mountain and the 16th climbing cave among the 36 caves.

2. Jiuquxi

Jiuquxi originated in Wuyishan Nature Reserve, with dense forests and a total length of 62.8 kilometers. A section of the river entering the scenic spot is not only influenced by the natural bending of the river, but also controlled by the fracture direction of several groups of strata, forming a deep meander, which makes the straight-line distance of the 9.5-kilometer-long river only 5 kilometers and the curvature is 1.9. Jiuquxi has clear water flow and abundant water resources, and the water quality reaches the national surface water standard.

3. Dahongpao Scenic Area

Dahongpao Scenic Area is located in the center of Wuyishan Scenic Area, in the famous Grand Canyon "Jiulong Pavilion". This is a deep and long valley controlled by the east-west fault structure. The valley is deep, and the long single-sided mountains on both sides of the nine dangerous peaks are towering, with rugged bones, parallel north and south, unique joint development and undulating peaks.

The world-famous Dahongpao grows on the cliff near the foot of Jiulong Mountain. There are a large and a small bonsai-style ancient tea garden, and six ancient and lush tea trees are flourishing. It has a history of more than 340 years.

In July 2007, 20 grams of Dahongpao tea was collected by China National Museum, which was the first time that modern tea was hidden in Guo Bo. Wuyishan will no longer be the mother tree Dahongpao tea.

4. water curtain cave

Water curtain cave in Wuyishan is one of the 72 famous caves in Wuyishan. Located in the north of Zhangtang River. Entering the scenic spot, there is a row of small waterfalls flowing down from the top of Xiabin Rock, which is called Little water curtain cave. After climbing the stairs, we arrived in water curtain cave. The dangerous rock at the top of the cave is obliquely covered, and the cave is deeply hidden in the convergent rock waist. The mouth of the cave is inclined, and the top of the cave is cool. Two flying springs pour down from the top of the inclined overlying rock 100 meters, just like two Youlong spouting dragon saliva, floating in the mountains, and like two bead curtains, hanging from the sky to the earth, so it is also called the bead curtain hole.

Water curtain cave is full of carved vertical and horizontal Dan cliffs. Among them, there is a seal script, which extracts Zhu's famous sentence, "Ask the canal so clearly, because there is flowing water at the source." There are inscriptions of "water curtain cave" on scenic spots in the Ming Dynasty, and stone-carved couplets of "It rains all day long on the eaves of ancient and modern times, and pearls are hung on the flowers in spring and autumn".
