The Dariganga ( Mongolian Дарьганга , Darjganga ) is a volcanic field in southeastern Mongolia on the border with China, which is an extension of the inner Mongolian field. It is believed to have originated in the Pleistocene or Holocene and consists of around 200 smaller cones . Their height varies between 25 m and 300 m and their state of erosion is very different. The field is traversed by northeast-oriented crevices that run parallel. The field may form a unit with the Dolon Nor field located in China . The field also borders the Abaga-Dalinuo field , which is located in central Mongolia. The two fields are believed to be the oldest volcanic fields of the Cenozoic era in East Asia. It is about 10,000 square kilometers.

rock

The rocks present in the field are less rich in potassium than the rocks in the north and center of Mongolia , but are nevertheless rich in alkali metals . It consists mainly of basalt , trachy basalt and foidite . Ultramafic xenolite is found in the southern part of the field bordering China . It is believed that the history that led to this rock is extremely complex.

cone

The most prominent cones in the field are the following:

Akhat (reverse magnetized )
Baruun-Nerte-Uul (reverse magnetized)
Bayan-Tsagaan Uul (reverse magnetized)
Dusy
Dzuun-Nerette (reverse magnetized)
Lun Uul (normally magnetized)
Shiliin Bogd Uul (normally magnetized)
