The Longgang volcanic field (LVF) of Northeast China has produced
a dozen maars with features of complex sequences.

The LVF covers an area of 1,550 to 1,700 km².

The LVF comprises over 150 Quaternary cinder cones, eight maars and tuff rings, and extensive basaltic to trachybasaltic lava flows, with rock types dominated by basalt, picro-basalt, trachybasalt, tephrite, and basanit.

The LVF is centred around coordinates of 42.33°N, 126.5°E.

Geochronology

Mineralization age: Cenozoic : 27.3 Ma to 0.2 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
