By using various oxide ratios in argillite, the paper discussed the situation of Paleoclimate and its evolutioary law from Carboniferous to Jurassic Period in Shanganning Basin. From Mid - Carboniferous to mid - Triassicepoch and late Triassic epoch to Antinian, the ratios of various oxides in argillite show two unsimilar cycles which gradually increase or decrease in vertical profile,accordingly, during the same period the paleoclimate exists the early and late two cycles i. e. from the moist to semimoist and semiarid climate.
Key words： argillite; ratio of oxide; paleoclimate evolution; shanganning Basin
