Errors Involved in the Taylor‘s Model for the Crustal Composition and Evolution—An Analysis of Their Causers

It is suggested in this paper that the famous Taylor‘s model for the composition and evolution of the continental crust consists of three closely related key links.These links include an assumption that the surfical environment has no effect on the sedimentary REE patterns and the REE patterns in sdhales can reflect the composition of their provenance,a discovery about the discrepancy of sedimentary REE patterns between Archean and Proteroxoic,and a deduction that there was a global scale K-granitoid event at the end of the Archean.Based on a detailed discussion,this paper substantially negates the rationality of the Taylor‘s model and argues 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 invoved in the Taylor‘s model is its wrongly neglecting the effect of the sedimentary envronment 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.
