[Edit this paragraph] Physical geography

1. Introduction to geography

The geographical coordinates are 107°52′-108°28′ east longitude and 27°32 north latitude ′-28°10′. It borders Yinjiang County, Shiqian County, Fenggang County and Dejiang County respectively. The county is located on the northern edge of the large slope transitioning from the Guizhou Plateau to the hills of western Hunan, between the Wuling Mountains and the Dalou Mountains. Controlled by structure, lithology and the Wujiang River system, it presents a variety of landforms such as peaks and mountains, gentle hills, valleys, river valleys, and stone forests. The highest point in the territory is Zhangziyan on the southeast edge, with an elevation of 1,434m. The lowest point is at the Wujiang River exiting the county in the north, with an elevation of 343m, and the maximum relative height difference is 1,091m.

The main stream of Wujiang River divides the county into east and west halves from southwest to northeast, from the bottom of Wujiang Valley to the intermountain basins and then to the blocking mountains on the east edge and northwest, thus forming the boundaries of the county. The eastern edge and northwest are high, the central Wujiang River Valley and other valleys are low, and the east and west edges are the basic outline of a "V" shape that slopes toward the Wujiang River. The rivers in the county belong to the Wujiang River system. The Wujiang River runs through the county from the southwest to the northeast. The river section in the county is 78.13km long. The tributaries on both sides are distributed in a dendritic shape. There are 28 rivers with a drainage area of ??more than 20km. The total length of the river is 457.25km. Including the 78km of the Sinan section of Wujiang River, the total is 533.25km. The river network density is 24.3km/100km.

Based on the internal and external forces and surface morphology that form the landforms, the landforms in the area are divided into four types: structural erosion and erosion of low mountains, dissolved hills and valleys, erosion and erosion of low mountains and valleys, and erosion and accumulation.

II. Stratigraphy lithology

The strata exposed in the county from oldest to youngest are Cambrian, Ordovician, middle and lower Silurian, Permian, and Triassic The middle and lower parts of the system. The Triassic and Permian strata are the most widely exposed, followed by the Silurian and Ordovician strata, and the Quaternary strata are scattered. The missing strata include the Devonian, Carboniferous, Jurassic, and Cretaceous.

3. Geological structure

The geological structure of Sinan County is on the western edge of the stable platform of the Xuefeng Ancient Continent, and regionally it is located to the north-east of Fenggang in the Zunyi fault arch of the Tailong in northern Guizhou. It is a tectonic deformation zone. Therefore, faults and folds develop, creating the unique geological and geomorphological environment of Sinan County.

It is mainly characterized by two groups of tectonic systems: NNE and NE, with the NNE structure as the main structure. It was formed in the Yanshan period and is composed of folds and high-angle compressive faults arranged roughly in parallel, in the shape of "multi" Arranged twisted tectonic forms. The folds and faults bend in an "S" shape to the east, and tensile and tensile-torsion faults develop in the bending parts. The syncline is open and the anticline is narrow. The main folds include the Xujiaba syncline, Tangtou syncline and the Yiaoxi anticline; the main faults include the Daheba and Shiqian compression faults. The second is the northeast-trending structure, which was formed before the Snow Peak Period and mainly manifests itself as a series of roughly parallel compression-torsion faults. The main areas in the area are the Sinan compression-torsional fault and the Tangtou compression-torsional fault, both of which are large regional faults.

IV. Geological Disasters

Sinan is located on the active fault belts of Sinan, Tangtou and Shiqian regions, and has experienced frequent tectonic activities in recent times. According to the Records of Sinan Prefecture and County, Sinan is a micro-seismic-prone area. There have been more than 10 earthquakes in Japan from 1884 to 2000. The largest recorded magnitude in history was 5.25, which is equivalent to 6.3 degrees. Recently, a magnitude 3.8 earthquake occurred on August 8, 1996. In 1995, the national seismological department determined that the basic earthquake intensity of Sinan County was less than the VI zone.

5. Natural Resources

The barite mine is a low-temperature hot night type deposit, which is distributed in Wenjiadian Town and Dabachang Town. Wenjiadian Laochangao Barite Mine Mine, no geological work has been carried out but only surface exploration, is about 1.5KM long, 12~15m wide and 8~1Om thick. A 500m long barite mine is exposed on the surface and is of high quality.

The mercury mines include Shachang mercury deposit and Liujing mercury deposit, which are hot night type deposits. Shachang mercury mine and Liujing mercury mine are produced in Tianqiao Township and Changba Township respectively. The mercury deposit is located in the Dabanchang anticline. The surrounding rock of the mercury deposit is the limestone of the Qingxudong Formation (∈1q) of the Lower Cambrian System. The mercury content is 0.009~0.561%. The cinnabar of the Liujing mercury mineralization point is found in Zhangshuiping. In the ∈2-3 of 1n crushed dolomite, calcite geodes or calcite veins in cherry and cherry places, the particle size is generally 0.1~0.2mm, and the mineralization is weak.

Iron ore resources occur at the bottom of the Wujiaping Formation of the Upper Permian System and in the Loushanguan Group strata of the Middle and Upper Cambrian System. Occurs in the west wing of the Xujiaba syncline at the bottom of the Wujiaping Formation of the Upper Permian System. The discovered iron ore resources include the Shatuo Iron Mine in Xujiaba Town, the Gaicao Iron Mine in Zhangjiazhai Town, and the Xiaowujia Iron Mine in Donghua Township. Ore point, the iron ore is an iron ore formed by the weathering of pyrite-containing clay mudstone. The iron ore is produced in a layered lens-like shape. The length of the ore body extending along the slope depends on the depth of the wind oxidation zone. Sampling analysis TFe: 30~45.26% , S: 0.051～1.2%, P: O.032～O.5%, (CaO MgO Si02 hl203): O.3～O.5%, no systematic geological work has been carried out at the above iron ore points. The only iron ore that exists in the Loushanguan Group strata of the Middle and Upper Cambrian is the Daxing Iron Mine in Dabachang Town. It is an oxidized iron ore. After sampling and analysis, TFe: 66%. It has been since the Great Leap Forward period in 1958. State-owned Daxing iron ore smelting and mining.

The lead-zinc deposit is located in the axis of the Daheba anticline and occurs in the secondary fault zone. It is a hot night type deposit.
