In this paper, some characteristics of Holocene Series, upper Pleistocene Series and active tectonics in Laizhou Bay segment of Tan-Lu Fault Zone are analysed by use of the shallow seismic surveying profiles. The tectonic action occurred at the end of Pleistocene epoch made upper Pleistocene Series form faults and folds, and a long and narrow arch fold was generated along the east main fault of Tan-Lu Fault Zone. At the two sides of the west main fault, the inferior cross faults (E—W) were developed fully, and they were tension normal faults with high angles.
