THE STRUCTURE IF THE QUATERNARY SHEET IN THE PETROZAVODSK BAY OF LAKE ONEGA ACCORDING TO SEISMOACOUSTICS
In: Moscow University Bulletin Series 4 Geology, Heft №1 (2024), S. 123-129
We present the results of seismoacoustic works carried out in the Petrozavodsk Bay of Lake Onega, the goal was to study a near-surface geological section. Seismoacoustic investigations were presented by the reflection method in a modification ultra-high resolution seismic survey. During the office work, the data were processed and interpreted, in which five seismic complexes were identified and correlated with the information about the lake structure. The result of the work was the maps construction of all five identified reflecting horizons covering all Petrozavodsk Bay. It was possible to estimate the sediments abundance and thickness corresponding to each complex.
Study of Onega lake Petrozavodsk bay sub-bottom sediments using complex geophysical and geological data analysis
In: Moscow University Bulletin. Series 4. Geology, Heft 4, S. 98-104
This article examines the results of geological interpretation of marine engineering data acquired in Onega lake. The survey included marine seismic acquisition and geological sampling. Seismo-stratigrafic units were picked according to processed seismic data. Survey results allowed to make a seismo-stratigrafic column of quaternary sediments of Onega lake. The column could be used to analyze the structure of open part of the lake as well.
