摘要
位于黑龙江畔的一架山火山 ,又称四季屯火山。有人认为它是第四纪更新世火山 ,有人认为是白垩纪火山。考察发现的种种证据表明 ,所谓一架山火山实际为玄武质熔岩残丘 (团山 ) ,其生成时代为白垩纪中新世 ,不属于第四纪火山。
Discussing the features of the Yijiashan volcano,which is also called the Sijitun volcano.The result shows that it is only abasaltic lava unaka,and it may be finished from the Certaceous period to the Miacene epoch.It is not activated at Quaternary as some authors has discussed.
