Is it accurate for Shangyou to tell fortune with an oilstone?

Geographical environment of Shangyou County

The rock types in Shangyou County are different due to different landforms. There are mainly acidic crystalline rocks, argillaceous rocks, river alluvium and Quaternary red clay. The county is located in the hilly and mountainous areas in the middle of Luo Xiao Mountains, with landforms in the county, with mountains in the northeast, northwest and southwest, hills and valley basins in the southeast.

Rock types: acid crystalline rocks are mainly granite and granite porphyry. Starting from the middle section of the Luo Xiao Mountains in the northwest, it extends to the southeast and southwest branches, mainly distributed in middle and low mountain towns such as Wu Zhifeng, Qian Ying, Shuiyan, Ziyang, Shui Mei, Shexi and Dongshan. Weathered materials have coarse particles, containing more quartz sand and gravel, forming acidic crystalline red soil, argillaceous soil and argillaceous field.

Purple sand shale includes purple glutenite, purple sandstone, purple shale and purple mudstone. Mainly distributed in low hilly areas, there are many oilstones and social streams, and there is also a small amount of plum water. The soil formed is purple sandy mud field and purple soil, which is rich in mineral nutrients such as calcium, potassium and phosphorus, and is a good soil-forming parent material in the county. River alluvium is mainly distributed in the valley terraces on both sides of the upstream river, Sixia River, Ziyang River and Qianying River. The soil formed is tidal sand mud and tidal sand mud field. Quaternary red clay is distributed in low mountains and hills. It is ice water deposit, which was formed after a long-term hot and humid climate. Generally, it is covered with purple glutenite, purple sand shale and purple sandstone. The lower part of the typical profile structure is gravel layer, followed by reticular layer and homogeneous red soil layer. The soils formed are Quaternary red clay, red soil, yellow soil and yellow soil. The altitude of Zhongshan is above 1000 meters, and the relative height is above 500 meters. It is mainly distributed in Wu Zhifeng, Pingfu, Shuangxi, Si Xia, Ziyang and other towns in the west and north. The low mountains with an altitude of 200-500m are mainly distributed in Doushui Town in the southwest and the edge of dongshan town. There are four peaks 1000 meters above sea level along the county border in the west and north, among which the third peak of Yun Qi Mountain (Dingguozhai) bordering Hunan and Chongyi is 1920 meters above sea level, which is the highest point in the county. Most of the rocks are granite and high rocks. Vegetation is mostly pine, fir, bamboo, white grass and reed dustpan. Bamboo and wood resources are abundant. The elevation of hills and hills is 300 ~ 500m, and the relative height is100 ~ 200m; The central hills are 200-300m, with a relative height of 50-100m; The elevation of low hills is below 200 meters, and the relative height is less than 50 meters. Mainly distributed in Huangbu, Dongshan, Shui Mei, Youshi, Shexi, Anhe and other towns, with low terrain and rivers running through it. Most rocks are metamorphic rocks, and some are granite, purple sand shale and seasonal sandstone. Vegetation coverage is slightly poor, and there are different degrees of soil erosion. This is a grain, oil and cash crop area.

Intermountain basins There are intermountain basins of different sizes between hills or mountains, and most of them are long belts with low terrain in Shaanxi. Qian Ying, Shuiyan, Shexi, Youshi, Dongshan and Huangbu basins are the largest, with rivers running through them, gentle slopes and wide river valleys, which are formed by the accumulation of new Quaternary sediments. It is an area with fertile land, concentrated farmland, dense population and developed agriculture in the county. The county is rich in kaolin, granite, lead, zinc, silver and other mineral resources. According to relevant data, the kaolin reserves are 2 1.82 million tons; Granite reserves are 2.52 million cubic meters, and lead-zinc-silver reserves are 277,400 tons.

There are mainly tungsten, lead, zinc, copper, molybdenum, silver, cadmium, bismuth, tin, iron, gold, rare earth, porcelain clay, fluorite, limestone, crystal stone, potash feldspar and coal. surface water

By the end of 20 13, according to the county's average annual runoff of 3.52 billion cubic meters, the runoff in good years reached 4.32 billion cubic meters, and the total runoff in extremely dry years reached 165 billion cubic meters. The average annual runoff of arable land per mu was 8620 cubic meters, which was higher than the national average, providing favorable conditions for the development of agriculture, fisheries and pig production. Because of rich runoff, many rivers and large drop, there are abundant hydropower resources. The total drop of rivers in the county is 2255 1 m, and the reserve of hydropower resources is197,000 kw.

underground water

There are three places with large underground hot water: one is Pingfu village warm pool hot spring, which is at the foot of the mountain at an altitude of 420 meters. The hot spring is 300 meters above sea level, the water temperature is 39.5℃, and the flow rate is 2.8 1 liter/second. The other is the hot spring in Hot Water Village of Wu Zhifeng Township. Under the mountain at an altitude of 500 meters, the hot spring is at an altitude of 4 15 meters, the water temperature is 44℃, and the flow rate is 1.627 liters/second. Both places use hydrothermal method to overwinter water hyacinth and African crucian carp. There is an African crucian carp farm in Hot Water Village. There are also small hot springs in Xiao Shuang Village, Wu Zhifeng Township and sedan chair-topped mountains in the north.
