摘要
在参加 1∶ 5万四海幅区域地质调查过程中 ,发现并实测了该剖面。通过对铁岭组岩性、岩相、生物、岩石化学的初步研究 ,恢复了铁岭期沉积环境的演变 ,指出了在该区研究铁岭组的地层学及矿床学意义。
This section plane was found and measured on the spot during the 1/50000 areal geological investigation of Sihai breadth.Through the primary research on lithology,lithofacies,biology,petrochemistry of Tieling formation,we recovered the evolvement of sedimental environment of Tieling Period and gave the significance of stratigraphy and ore deposits to research Tieling formation.
