摘要
Well Hongcan 1 is a parameter borehole drilled in Zoige depression, western Sichuan Province, China. Stratigraphy revealed by the data that Borehole Hongcan 1 is a suit of the Middle-Upper Triassic turbidities rock association without any fossil organism with diagnostic value. Combined with the basic characteristics of the strata of Borehole Hongcan 1, and according to the characteristics of rock assemblage, grain-size statistics, heavy mineral assemblage and geochemistry of rocks, the paper thinks that the strata of Borehole Hongcan 1 can be divided into Zhuwei Formation, Zagunao Formation and Zanaishan Formation.
