Nature

Dong Van Karst Plateau Geopark is located in

Quản Bạ. The area of the geopark is 2356,8 km2. The average elevation within the geopark is 1400 to 1600 meters above sea level.[1]

About 80% of the area of the geopark is covered by limestone. There are many huge mountains here, the highest one is Mount Mieu Vac (1971 m), meanwhile, there are also many deep canyons, the deepest one is Tu San (about 800 m).

The climate of the geopark varies depending on elevation, but the majority of the park has a temperate climate with two seasons: rainy season and dry season. The annual mean temperature is 24 to 28°C, but it may drop down to 5°C in the winter.

Geology

The geopark is located at an extension foot mount East of the Himalayas.

Frasnian-Famennian (360 million years ago) and Permian-Triassic (250 million years ago). This includes 3 groups of sedimentary, igneous and metamorphic rocks, as well as stratigraphic, lithostratigraphic and biostratigraphic specificities. Its paleontological diversity shows 19 groups of valuable ancient organisms like ancient fish, ancient flora, brachiopods (eurispirifer tonkinesis), bivalves, trilobites, foraminifera, corals, conodonta, crinoidea and fossilized paths of molluscs
.

The Geopark has two natural conservation areas rich in fauna and flora species such as

Southern serow (a solitary mountain goat) and many species of bird. Moreover, the unusual and mysterious Tonkin snub-nosed monkey is one of the 25 most endangered
species of primate in the world. It is only found in Hà Giang province and was believed extinct until its rediscovery in the early 1990s.

The oldest fossil found in the park was found at Lũng Cú peak, and has been dated to 540 million years old.
