遼東灣部分地區(qū)第四紀(jì)沉積物特點(diǎn)及沉積環(huán)境分析
[Abstract]:Oceanographers have always paid close attention to the Quaternary marine problems, especially the characteristics of sediments and the evolution of sedimentary environment. Jinzhou Bay is a semi-enclosed bay located on the western side of Liaodong Bay. It is the focus area of China's marine economic development and development, and is also one of the important sea areas of China's opening-up strategy. The study of sedimentary characteristics and sedimentary environment of sediments in Jinzhou Bay is of great significance for understanding the Bohai Sea. This paper is mainly based on neotectonic kinematics, guided by geomorphology, geochronology, stratigraphy, sedimentary dynamics, based on modern analysis and testing techniques, and adopts comprehensive analysis, comparative analysis, mathematical geological method, and so on. And make full use of the collected research results and data, as well as field investigation, to establish the surface sediment samples, borehole samples of the study area, plan, profile, contour map, etc. The characteristics and sedimentary environment of Quaternary sediments in Jinzhou Bay, Liaodong Bay, Bohai Sea are described in detail. The surface sediments in the study area are controlled by various types of factors, mainly silty clay and silty clay, and some individual interbeds contain silty sand. The sediment is obviously land-friendly. It is concluded that the sediment in the study area mainly comes from the input material from the coastal rivers. In addition, the erosion of the coastal islands and the human activities (the construction of Lingyuan Reservoir) also provide a certain source of material. In the study area, both the grain size and sediment thickness of Quaternary sediments are reflected in different drilling holes, the sedimentary sequence and the corresponding characteristics are different. The main sediments are silt, silty clay and silty sand. Coarse gravel sand and middle sand can be divided into Holocene Q4 (main marine sediments and marine-continental interbeds) and late Pleistocene Q3 (alluvial deposits and marine-continental intersections) according to the Quaternary strata. The trend of vertical thickness of sediment in each sediment layer is observed as a whole. During the ice age, the climate is cold and dry, forming the continental strata, and the interglacial period is warm and humid, forming the marine strata, and the sea-land interaction deposits are formed between the glacial period and the interglacial period.
