Fishing In Parts Of The Quaternary Sediment Features And Sedimentary Environment Analysis

Over years,oceanographers are very concernedabout issues related to marine Quaternary,i nparticular the characteristics of the sediment and sedimentary environment evolution.Jinzho u Bay is a semi-enclosed Bay of LiaodongBay,locatedinthe center of Bohai economic circle,i s an important area of marine economy development in China.Discussionon characteristics of sediments of Jinzhou Bay sediments andits sedimentary environment,for understanding the Bohai Sea is of great significance.Paper main to new tectonic movement learn for based,and to landforms learn,and geological era learn,and formation learn for guide,and deposition dynamics,to modern analysis,and test technology for relies on,used integrated analysis method,and compared analysis method,and mathematics geological a quantitative method,and full using has collected of research results and information,and field study,on research district of surface deposition sample,and drilling samples established plane figure,and profile figure,and equivalent line figure detailed description Bohai Liaodong Bay Jinzhou Bay near waters Quaternary deposition real of features and deposition environment.Surficial sediments in the study area under the control of factors such as strength of the hydrodynamic type dominated by silty clay,silty clay,local sandwich containing silt sediments.An obvious Pro-land of the sediments to determine sediment within the study area comes mainly from coastal rivers enter the material,in addition to coastal islands of erosion and human activities(construction of Lingyuan reservoir)also provides some sources.Research district within different drilling deposition layer sequence features different,Quaternary deposition real of grain degrees and deposition thickness are has difference,main is mud,and mud quality powder quality clay,and powder quality clay,and po,wder sand,and rough gravel sand,and in the sand,according to Quaternary formation can divided for:new Commission Q4,and late update Commission Q3.Overall sediment at each level on the vertical light down on gross trends.Ice age when the climate is cold and dry,forming continental strata,interglacial epoch when the climate is warm and humid,formation of marine facies strata,sea-land interaction between glacial and interglacial sediments.
