context_page_description: The Xiong'er Volcanic Belt is a 1770 to 1800 million year-old group of volcanic rocks located on the southern edge of the North China craton. It covers an area of approximately 60,000 km² and varies from 3000 m to 7000 m thick. The perimeter of the volcanic belt is composed of three faults: the Jianxian-Lintong fault to the northwest, the Luoyang-Baofeng fault to the northeast, and the Luonan-Luanchan fault to the south. The volcanic belt formed at a time in Earth's history when all of the continents were joined together forming the Supercontinent Columbia, the earliest known supercontinent. The Xiong'er Volcanic Belt is very important because it can provide valuable information to help piece together the formation and breakup of the Supercontinent Columbia and the North China craton by identifying what type of boundary was located on the southern edge of the North China craton.
context_section_description: The Xiong'er Volcanic Belt (Chinese: 熊耳群火山岩; pinyin: Xióng'ěr qún huǒshānshí) is a 1770 to 1800 million year-old group of volcanic rocks located on the southern edge of the North China craton (Figure 1).  It covers an area of approximately 60,000 km² and varies from 3000 m to 7000 m thick. The perimeter of the volcanic belt is composed of three faults: the Jianxian-Lintong fault to the northwest, the Luoyang-Baofeng fault to the northeast, and the Luonan-Luanchan fault to the south (Figure 2).
