Abstract:
Based on the field investigation in Hongliugou of Yabulai Basin, the results indicate that the main sedimentary facies is Jurassic fan delta, which can be divided into three subfacies including fan delta plain, fan delta front and pre-fan delta and six microfacies including braided channel, natural levee, crevasse, marsh, underwater distributary channel, underwater distributary interchannel, mouth bar, sheet sand, and so on. According to the field characteristics of sedimentary structures, the channel deposits developed in the condition of strong hydrodynamic, mouth bar deposits of fan delta front developed in the condition of alternating dynamic of strong and weak, and the pre-fan delta developed in the condition of relatively stable hydrodynamic. According to the analysis of trace elements in six samples of mudstone with spider diagrams, the results show that the contents of V, Sr, Rb, B are relatively high, but Zr, Cr, Ni are relatively low. Calculations of climate index and the ratio of mass factions of Fe2+ and Fe3+ show that the sedimentary environment was weak oxidation and semi-arid in Middle Jurassic.
