摘　　要：It is suggested in this paper that the famous Taylor’s model for the compdrition and evolution of the continental crust consists of three closely related key links. These links include an assumption that the surficial environment has no effect on the sedimentary REE patterns and the REE patterns in shales can reflect the composition of their provenancel a discovery about the discrepancy of sedimentary REE patterns between Archean and Proterozoic, and a deduc-tion that there was a global scale K-granitoid event at the end of the Archean. Based on a de-tailed discussion, this paper substantially negates the rationality of the Taylor’s model and ar-gues that its three critical links be three great errors indeed. Moreover, some other deficiencies or problems it confronts are described in this paper. The authors suggest that what led to the errors involved in the Taylor’s model is its wrongly neglecting the effect of the sedimentary en-vironment on the chemical composition of sediments, and that the environment should be an important factor affecting the distribution patterns of trace elements in the sediments.It is suggested in this paper that the famous Taylor's model for the compdrition and evolution of the continental crust consists of three closely related key links.
