The authors by their own statement do not intend to make a general criticism of the work but which only to point out these specific errors: 1) There is no justification in assigning all the massifs to the junction zone of East and West Sayans. It is incomprehensible to include such dissimilar massifs as the gabbros of Kazyr and the granitic Kryzhin range, both because of age and form; 2) There are no chromite deposits in the West Sayans; 3) The use of an effusive-schist formation in the Upper Proterozoic is incorrect; it should read series; 4) What do Ordovician faults have to do with the Lysansk massifs? 5) There are serious errors and omissions in the petrography of the Lysansk complex, on which the authors elaborate; 6) The TiO2 deposits in gabbros were discovered not in 1956, as claimed, but in 1954 by two other geologists; 7) The sequence of the emergence of secondary minerals from a magmatic melt “can only be visualized;” 8) They object to “superimposing” an autometamorphic phase on the mineralization; 9) They object to the concepts of the origin of Lysansk intrusions, as being “in the dogmatic form of an article of faith.” — M.A. Klugman  相似文献
