本文主要研究北部湾北部近岸海区表层沉积物、近岸出露的地层和河床样品中的重矿物。从而,比较近岸陆源物质和浅海沉积物的重矿物组合及其含量变化,以确定它们之间的亲缘关系和本区泥沙运移的趋势。
This paper mainly studies surface sediments, offshore exposed formations and heavy minerals in riverbed samples in the northern Beibu Gulf offshore area. Therefore, the heavy mineral assemblages and their contents in the near-shore terrigenous and shallow-sea sediments were compared to determine their genetic relationship and the trend of sediment transport in this area.
