    内蒙古科右中旗德日乌兰哈达中心式火山机构

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

      摘要
    • 摘要: 德日乌兰哈达中心式破火山机构是晚侏罗世时火山活动产物，围斜内倾，环状、放射状断裂发育，环状断裂以各种岩脉充填.火山通道为粗面岩所占据，测其同位素年龄140.8±2.0 Ma.

       

      Abstract: 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.
