Śledzenie struktur geologicznych i ruchów tektonicznych w osadach neogeńskich metodą sejsmiczną w aspekcie geologiczno-inżynierskim
(Wydawnictwa AGH, 2008) Kaszubowski, Leszek Józef
This paper presents results of the tracking of geological structures and tectonic movements in the Neogene deposits by the aid of seismic method in engineering-geological aspect. Author have analysed the area of the Kopań Lake and Wicko Lake spit. Seismic research with use of the apparatus CS-5G-1 (6 channels) as high-resolution seismic investigations were carried out along the designed profiles, which are situated near to the shore of the Baltic Sea. During the seismic investigations, seismic reflective waves were recorded in measuring range Z = 100 ms. The measuring range was useful for the seismic waves, which have penetrated the deeper geological layers even to the top of Pleistocene bedrock. In this case seismic waves reach a value of 80-100 m below the terrain level. Distances between geophones were 10 m, and between profiles 40 m. During the research, there was used constant intensification of seismic impulses amounting from 66-72 dB. Measuring range R = 100 ms causes, that seismic waves reach a frequency of 5 kHz. For the verification of the seismic investigations were executed the geological drillings located on the beach and on the area of the Wicko Lake.
