| 摘 要： | 鲁西普遍发育的高角度正断层和一系列近东西向、近南北向的地堑、半地堑式断陷盆地，表明在中新生代，本区普受到大规模的伸展作用，基底拉开的累积水平位移可达３０余公里，形成的伸展构造不仅控制了鲁西煤与油气盆地的赋存与分布，对煤矿区的构造发育、水文地质条件、瓦斯的赋存等均产生的重大影响。

| Abstract: | The geological henomena that high angle normal faults and a series of graben or semi graben types of faulted basins in nearly EW or SN directions developed widely in western Shandong indicated that this area suffered large scale extensional movement in Mid Kainozoic.The accumulated horizontal displacement in basement is up to more than 30 km.The extensional structures not only control the occurrence and distribution of coal,oil and gas basins,but also influence the structure development in mining area,hydrological conditions and gas storage. |
