Distribution and characteristics of sea sand resources in Binhai Xincheng Area, Weihai City

Data from submarine sediment samples, shallow seismic profiles, geological drilling, and multi-beam survey in Binhai Xincheng Area in the east of Weihai City were analyzed, from which the type, distribution and sedimentary environment of sea sand resources were clarified. Results show that: the sea sand resources in the study area are distributed in mainly the vicinity of Jiming Island and Cangjia Island. They are all buried placer deposits, dominated by silty sand and fine sand with high content of mud, so they can be used for backfill. The buried placer deposits were formed since the end of the late Pleistocene, and the main genetic types are paleo-alluvial, residual, and marine sediments.
