1. Characteristics of Ang Ang Creek Volcano Group:

Angangxi Volcano Group is located in Mudanjiang City, Heilongjiang Province, China, and it is one of the newest volcanic groups in Chinese mainland. This volcanic group consists of dozens of volcanoes, which are relatively young in shape and relatively active in geological activities. The highest volcanic peak is Ang Ang Xigang Peak, which is about 1346 meters above sea level. Ang Ang Creek has well-preserved and large-scale railway buildings in the Middle East, which is one of the excellent models to appreciate the various styles of railway buildings in the Middle East.

2. Geological background of Ang Ang Creek Volcano Group:

Angangxi Volcano Group is a tectonic volcano, which was formed in late Quaternary, late Pleistocene and early Holocene. This area is located in the tectonic metasomatism zone where the Pacific plate moves eastward and collides with the Eurasian plate, and the crustal activity is frequent.

3. The eruption history of Ang Ang Creek Volcano Group:

The eruption of Ang Ang Creek Volcano Group mainly occurred in Holocene from 654.38 million years ago to thousands of years ago. Volcanic eruption has formed a series of landforms such as crater, overflow platform and volcanic fault. The eruption type of Angangxi volcano group is mainly basalt, and the ejecta are mainly basalt and tuff.

4. Geological value of Ang Ang Creek Volcano Group:

Ang Ang Creek Volcano Group is one of the newest volcanic groups in Chinese mainland, which is of great significance to the study of volcanic activity and volcanic eruption process. The geological investigation and study of this volcanic group can provide important clues for understanding the geological evolution of northeast China. In addition, the area where Angangxi Volcano Group is located is also rich in geothermal resources and has the potential to develop and utilize geothermal energy.

Conclusion:

The latest volcano in Chinese mainland is Ang Ang Creek Volcano Group, located in Mudanjiang City, Heilongjiang Province, which is a tectonic volcano group. This volcanic group was formed from the late Pleistocene to the early Holocene, and its eruption history spanned tens of thousands of years. Ang Ang Creek Volcano Group is not only of great value to volcanology research, but also provides potential opportunities for the development and utilization of geothermal resources.
