    Abstract
  • The unconformity is formed due to the tectonic movement and the eustatic sea level change.The unconformity structure is very important for the pool forming.If the weathered clay is thick enough, it can become good capping layer.The pores, fissures and their connecting systems in the sapropelic rock provide good migrating channel and accumulating place for oil.Studying the mineralogical and geochemical characteristics of unconformity structure is the basic of the structure division which is important for the exploration of unconformity oil traps.The unconformity includes three structure types: the structure with weathered clay and the sapropelic rock, the structure only with sapropelic rock and the structure which formed during interruption of sedimentation.The mineralogical and geochemical examination results of Yihezhuang uplift pre-Tertiary buried weathered crust and some typical weathered crusts with weathered clay and sapropelic rock are summed up and the mineralogical and geochemical characteristics of such unconformity structure are given in this paper.The primary minerals that are not resistible to weathering such as feldspar and mica decreased and the secondary clay minerals such as kaolinite and illite increased gradually.The Fe and Al elements are rich in the clay layer and the upper part of the sapropelic rock.The Ca and Na elements lost heavily.But the contents of K and Mg elements are complicated owing to the factors such as replacement of these two elements.
