鲁中南盆地内部构造地貌与第四纪地壳运动

TECTONIC LANDFORMS AND QUATERNARY CRUSTAL MOVEMENTS IN THE BASINS OF THE SOUTHERN CENTRE OF SHANDONG PROVINCE

鲁中南盆地内的地貌受次级断裂构造的严格控制。盆地中的剥蚀面—临城期剥蚀面在第四纪时被抬升。通过对这些形成于第三纪末至第四纪早期的临城期剥蚀面抬升程度的对比,可估计抬升量并确定地壳抬升轴。这种结论可以对蒙阴县金刚石砂矿的探寻提供线索。

The landforms in the basins of southern centre of Shandong Province are controlled strictly by the secondary faults. The denuded surfaces called Lincheng de-nudation surfaces in the basins were elevated during the period of the Quaternary. By comparing the relief levels of Lincheng denudation surfaces which formed during the period of the end of Tertiary to the early Quaternary, the lifted range can be estimated and the elevating axe of the crust can be found out. This conclusion can offer some clue to seeking alluvial diamonds in Monyin County.
