    THE DERIWULANHADA CENTER-TYPE VOLCANIC EDIFICE IN HORQIN YOUYI ZHONGQI, INNER MONGOLIA

    • The Deriwulanhada center-type caldera edifice is the product of Late Jurassic volcanic activity, with periclinal introversion and developed annular and radial faults. The annular fractures are filled with a variety of dikes. The volcanic vent is occupied by trachyte, which is dated by isotopic age of 140.8 ±2.0 Ma.
