图中褶皱构造的类型及其形成的地质时代.doc

...:..1、、、-11-21优质解答1背斜二叠纪之后侏罗纪之前2F1正断层二叠纪之后白垩纪之前F2逆断层二叠之后白垩之前3奥陶纪至二叠纪沉积接着形成背斜接着断层发育然后岩浆岩侵入最后沉积白垩系地层追问:麻烦解释在具体点谢谢追加分追答:1背斜因为褶皱核部为老地层翼部为新地层。年代褶皱上一直有二叠系地层,后与侏罗系呈角度不整合接触故可确定时间2F1正断层(可以根据褶皱的核部在断层下盘变宽说明下盘抬升)时间应该是二叠纪之后同时断层切割花岗岩(花岗岩切割了侏罗系地层)说明是在侏罗纪到白垩纪之间;同理也可以判断F2断层时间是二叠之后白垩之前3奥陶纪至二叠纪沉积接着形成背斜接着断层发育侏罗纪至白垩纪时期本区再次沉降接受沉积,期间有花岗闪长岩体侵入构造地质学,综合分析题,这个答案怎么写得,最好是标准答案。 "点击查看大图"\t"_blank" 点击查看大图"\t"_blank""./share/?url=http%3A%2F%2Fzhidao.%2Fquestion%2F1669504524812280467%3Fsharesource%3Dweibo&title=%E6%9E%84%E9%80%A0%E5%9C%B0%E8%B4%A8%E5%AD%A6%EF%BC%8C%E7%BB%BC%E5%90%88%E5%88%86%E6%9E%90%E9%A2%98%EF%BC%8C%E8%BF%99%E4%B8%AA%E7%AD%94%E6%A1%88%E6%80%8E%E4%B9%88%E5%86%99%E5%BE%97%EF%BC%8C%E6%9C%80%E5%A5%BD%E6%98%AF%E6%A0%87%E5%87%86%E7%AD%94%E6%A1%88%E3%80%82_%E7%99%BE%E5%BA%A6%E7%9F%A5%E9%81%93&pic=http%3A%2F%2Fimg.%2Fimg%2Fiknow%"\t"_blank"om%2Fimg%2Fiknow%"\t"_blank"Metroid_Snake | 浏览14次  2015-01-1521:502015-01-1610:45最佳答案除去早第三纪外,地层从老到新为奥陶纪、志留纪、泥盆纪,断代缺失石炭纪、二叠、三叠纪地层,上覆//?wd=%E4%B8%8D%E6%95%B4%E5%90%88%E6%8E%A5%E8%A7%A6&tn=44039180_cpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1dBrHT3mHT1mhnkrj9hPHKB0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EnHmvrHRsPjRzPj6knWc3njfvPs"\t"_blank"不整合接触侏罗纪、白垩纪地
