| 摘 要： | 文中通过应用SHRIMP锆石微区U-Pb测年技术对马架山组凝灰岩进行了精确测年,判定其形成时代为早白垩世（123.6 Ma）,与长江中下游地区其他火山岩盆地形成时代类似.通过邻区对比,认为白垩纪长江中下游地区处于伸展构造背景.

| Abstract: | The dating technique of SHRIMP Zircon U - Pb was applied to determine the time of the Majianshan formation. Its formation age was the Early Cretaceous （123.6 Ma）and similar to other volcanic basin formation ages in downstream Yangtze River region. Compared with adjacent areas, the Majiashan is in the Yangtze River region Cretaceous extensional tectonic setting. |
