摘要

本文介绍了在地震剖面分析的基础上对赫尔半岛主要地质特征进行的开创性研究成果，并将其与钻孔地质剖面进行了比较。尖端结构的以下三个部分已确定：屏障基底（1）、屏障核心（2）和屏障上部（3）。随后，对其中区分的地震相进行了地质解释：白垩纪泥灰岩和石灰岩（1.1）、冰川泥地和碎屑岩（1.2）、冰川/湖沼/海洋成因的淤泥和粘土（1.3）、岩芯的障壁砂（2）以及障壁上部的砂和泥炭（3）。涵盖赫尔半岛水下斜坡尖端和周围海床地质结构的地质剖面图。确定了斜坡基底和海底远端砂崩积层的范围。本文首次在贺河半岛的这一地区作了横向剖面。

Seismic architecture of the tip of the Hel Peninsula, Poland

The article presents results of a pioneering research on the main geological features of the Hel Peninsula based on the analysis of seismic profiles and their comparison with geological cross-sections made on the basis of drillings. The following three parts of the tip structure have been identified: barrier basement (1), barrier core (2) and barrier upper part(3). Seismic facies distinguished therein were subsequently geologically interpreted as follows: Cretaceous marl and limestone (1.1), glacial till and diamicton (1.2), silt and clay of limnoglacial/limnic/marine origin (1.3), barrier sand of the core (2), and sand and peat of the barrier upper part(3). Geological cross-sections covering the geological structure of the tip of the Hel Peninsula underwater slope and the surrounding seabed. The slope base and the distal sand colluvium extent on the seafloor were determined. This paper is the first to present a crosswise section in this part of the Hel Peninsula.

期刊介绍： BALTICA is an international periodical journal on Earth sciences devoted to the Baltic countries region and the Baltic Sea problems. This edition as a Yearbook is established in 1961 by initiative of Academician Vytautas Gudelis. Since 1993, an Editor-in-Chief of the journal became Academician Algimantas Grigelis. BALTICA is published biannually (in June and December) in cooperation with geoscientists of the circum-Baltic States. BALTICA is publishing original peer-reviewed papers of international interests on various Earth sciences issues. The particular emphasis is given to Quaternary geology, climate changes and development of ecosystems, palaeogeography, environmental geology, as well as stratigraphy, tectonics, sedimentology and surface processes with relevance to the geological history of the Baltic Sea and land areas. Journal emphasizes modern techniques, methodology and standards. The journal structure comprises original articles, short reviews, information, bibliography.
