BackgroundThe Keluo volcanic field, like its better known neighbor to the south, the Wudalianchi volcanic field, contains many high-potassium basaltic cinder cones. Most cones to the NE are of Pleistocene to Tertiary age. Cinder cones of the Keluo volcanic field 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.
Ol-bearing leucitites are found from 3 volcanoes in the Keluo field: Dangzishan, Heishan and Muhenanshan. Muhenanshan volcano is currently the only one known so far at which ol-leucitites and trachybasalts coexist (Zhang et al, 1995).
