【Abstract】 The advantages of integrating stratigraphical features in studying the history of geological and biological evolution revive stratigraphy as the cornerstone of many branches of geosciences. In this paper, a briefing is given on elaborating the golbal chronostratigraphical hierarchy, reconstruction of paleoe-cosystem , research of bio-and geo-events, three-dimension geological maping and quantitative stratigraphy.更多还原
