Abstract

The authors regret that there are two aspects for the above article that we like to make corrections: (1) since the second batch of data is non-shale and the calculation standard of brittleness is different, some irrelevant data need to be removed.; and (2) writing form and unit of the formula need to be modified. These corrections do not affect the findings of the article. a) Fig. 12 (page 469) should be replaced with the new figure below. [Figure presented] Fig. 12. Comparison between the brittleness indices calculated by the mineral component and the rock mechanics parameters method. b) Fig. 13 (page 470) should be replaced with the new figure below. [Figure presented] Fig. 13. Brittleness indices of different shale lithofacies. c) The equations (Equations (4)–(9), Equations (11) and (12); just delete *100 from the original formula) should be replaced with the new equations below (page 470). [Formula presented] [Formula presented] [Formula presented] [Formula presented] [Formula presented] [Formula presented] [Formula presented] [Formula presented] d) On page 469, Sect. 4.3, first paragraph, line 11: “where Brit is the brittleness index, %” should be replaced with “where Brit is the brittleness index”. e) On page 469, Sect. 4.3, second paragraph, line 22: “where Brit is the brittleness index, %” should be replaced with “where Brit is the brittleness index”. f) On page 469, Sect. 4.3, sixth paragraph: “where ERrit is the normalized Young's modulus, %; E is the Young's modulus, Gpa; μRrit is the normalized Poisson's ratio, %; μ is the Poisson's ratio; Brit is the brittleness index, %.” should be replaced with “where ERrit is the normalized Young's modulus; E is the Young's modulus, Gpa; μRrit is the normalized Poisson's ratio, %; μ is the Poisson's ratio; Brit is the brittleness index.” The authors would like to apologize for any inconvenience caused.
