Abstract:

The results of research geological features and minerals in the seabed sediments Ha Tinh area has identified buried placer here has an intimate relation to the erosion of bedrock formations distributed in coastal and seabed Cua Nhuong area; By analyzing synthetic stratigraphic column of marine borehole log and shallow high resolution seismic interpretation of profile determine the morphology and structure of placer body (deposit) includes two main types: The first type consists of the coarse-grained sediments (sand, gravely sand, silty sand) related to ancient tidal flat, ancient shoreline, ancient riverbed lithofacies in the collection of seismic stratigraphy A, B, C; Type 2 consists of coarse-grained sediments in the valley closed development on the bedrock surface.
