中文摘要:
      利用井田勘探和矿井生产的地质资料,对上京井阳的构造特征进行了总结,认为该井田以褶皱为主,尤以翻卷褶曲为特征,并且其复杂的构造格局是在经受了多次构造运动而形成的,其形成过程可概括为四个阶段:含煤盆地形成阶段;Ⅰ级褶皱和辗掩断层形成阶段;Ⅱ、Ⅲ级褶皱和一系列正断层形成阶段;构造体系的叠加、改造和定型阶段。
英文摘要:
      The paper made a summary on struct ural characteristics of the Shangjing mine field by the use of geological data from exp loration in the minefield and mining produc tion.Figured out that the main structure fo rm in the minefield is fold, while the disti nguishing feature is convolute fold.The co mplicated structural framework was formed after multiple tectogenetic movements. Fou r stages of forming processes may be summed up:coal basin forming stage;first order fo lds and overthrusts forming stage;second a nd third order folds and a series of normal faults forming stage; tectonic system stac king, remolding and shaping stage.
