Khun Tan Range
The Khun Tan Range ( th, ทิวเขาขุนตาน or, erroneously, ทิวเขาขุนตาล) is a mountain range that occupies a central position in Northern Thailand. Most of the range is located in Chiang Mai, western Chiang Rai, Lampang and Lamphun Provinces. The geological composition of the Khun Tan mountains is different from the neighboring Thanon Thong Chai Range in the west and the Daen Lao Range in the north. Precambrian rocks are absent in this mountain chain which is thus not part of the Shan Hills system. The geology of the Khun Tan Range is homogeneous with the Phi Pan Nam Range further east and some scholarly works designate the Khun Tan as the "Western Phi Pan Nam Range", including it as part of the Phi Pan Nam Range, Phi Pan Nam Mountain System. Geography The Khun Tan Range begins south of the Kok River valley, at the southern end of the Daen Lao Range in Fang District. It stretches southwards in a north/south direction turning midw ...

Doi Tao District
Doi Tao ( th, ดอยเต่า, ) is a district (''amphoe'') in the southern part of Chiang Mai province in northern Thailand. Geography Neighboring districts are (from the west clockwise) Om Koi, Hot of Chiang Mai Province, Li of Lamphun province and Sam Ngao of Tak province. The south end of the Khun Tan Range reaches the east side of this district. History The minor district (''king amphoe'') was established on 16 October 1972 by splitting off the four ''tambons'' Tha Duea, Doi Tao, Muet Ka, and Ban Aen from Hot district. It was upgraded to a full district on 25 March 1979. Administration The district is divided into six sub-districts (''tambons''), which are further subdivided into 42 villages ('' muban''). Tha Duea is a township (''thesaban tambon Thesaban ( th, เทศบาล, , ) are the municipalities of Thailand. There are three levels of municipalities: city, town, and sub-district.

Wang River
The Wang River ( th, แม่น้ำวัง, , ) is a river in northern Thailand. Geography The Wang River is long. Its waters flow from north to south. The Wang River has its source in the Phi Pan Nam Range in Wiang Pa Pao District, Chiang Rai Province. One of the principal settlements along the river is Lampang, which is on the north bank of a curve in the river. From Lampang, the river flows southwards passing by Thoen into Tak Province. It joins the Ping River near Mae Salit, Ban Tak District, north of the town of Tak. The Ping River is a tributary of the Chao Phraya River. Tributaries Tributaries of the Wang include the Mo, Tui, Chang, and Soi Rivers Wang basin The Wang basin is part of the Greater Ping Basin and the Chao Phraya Watershed. The total land area drained by the Wang River and its tributaries is . Kiu Lom Dam (เขื่อนกิ่วลม) is on the Wang River about from Lampang town. References Wang Wang may refer to: Names ...

Ping River
The Ping River ( th, แม่น้ำปิง, , ), along with the Nan River, is one of the two main tributaries of the Chao Phraya River. It originates at Doi Thuai in the Daen Lao Range, in Chiang Dao district, Chiang Mai province. After passing Chiang Mai, it flows through the provinces of Lamphun, Tak, and Kamphaeng Phet. At the confluence with the Nan River at Nakhon Sawan (also named ''Paknam Pho'' in Thai), it forms the Chao Phraya River.

Kok River
The Kok River ( th, น้ำแม่กก, , ) is a tributary river of the Mekong that flows in Chiang Rai and Chiang Mai provinces in northern Thailand. Source The river originates in the Daen Lao Range, Shan State, Myanmar. It flows eastwards across the Myanmar–Thailand border, crossing at the Thai border town of Tha Ton ( th, ท่าตอน, also spelled "Thaton" ). It flows to Mae Ai District, Chiang Mai Province. Most of its length in Thailand is in Chiang Rai Province where it passes Mueang Chiang Rai District after which it bends northeastwards and flows through Mae Chan, Wiang Chai and Chiang Saen districts. It is a wide, shallow, and slow-moving river. There is about of small-scale whitewater halfway between the towns of Tha Ton and Chiang Rai. For several kilometres downriver from Chiang Rai, the river becomes a lake, until it reaches the irrigation dam near Wiang Chai. The Kok River is a tributary of the Mekong River, with its mouth at Sop Kok in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Shan Hills
The Shan Hills ( my, ရှမ်းရိုးမ; ''Shan Yoma''), also known as Shan Highland, is a vast mountainous zone that extends through Yunnan to Myanmar and Thailand. The whole region is made up of numerous mountain ranges separated mostly by narrow valleys as well as a few broader intermontane basins. The ranges in the area are aligned in such a way that they link to the foothills of the Himalayas further to the northwest. The highest point is Loi Leng, at 2,673 m elevation. Other peaks are 2,565 m Mong Ling Shan, 2,565 m Doi Inthanon and 2,563 m Loi Pangnao. All are ultra prominent peaks of Southeast Asia. Etymology The name of the massif or system of ranges, is derived from the Shan State and its peoples, said in its turn to be derived from the word "Siam", that occupies most of the Shan Highland area. Since it was relatively unexplored until recent times, the Shan mountainous region was referred to as the "Shan Plateau" in geographic works of the British coloni ...

Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards.
