Sintesi geologica

The Keluo volcanic field in NE China is located near the Russian border, S of the Heilongjiang (Black Dragon) River. Like its better known neighbor to the S, the Wudalianchi volcanic field, it contains many high-potassium basaltic cinder cones. Nanshan cone, located at the southern end of the field N of the Keluo River, may be of historical age, based on its youthful appearance, and Gushan may also be Holocene. Other cones to the NE are of Pleistocene to Tertiary. Cinder cones are located at the intersections of regional NE- and NW-trending lineaments, and were erupted through basement volcanic and sedimentary rocks of Jurassic-Cretaceous age, granitic rocks, and pre-Permian metasediments. There are unconfirmed reports of observed activity.

Sintesi da Wikipedia

Riassunto in inglese

Keluo is a dormant volcanic field 310 kilometers (190 mi) north-by-northwest of Daquijin in northeastern China. It is located at an intersection of regional lineaments trending northeast and northwest; the volcanoes were erupted through basement igneous and sedimentary rocks from the Jurassic to Cretaceous, through granite, and through pre-Permian metasediments. Like the Wudalianchi volcanic to its south, it contains high-potassium basaltic cinder cones.
