  Emergent Lorentz symmetry and chiral anomaly are well known to play an
essential role in anomalous transport phenomena of Weyl metals. In particular,
the former causes a Berry-curvature induced orbital magnetic moment to modify
the group velocity of Weyl electrons, and the latter results in the chiral
magnetic effect to be responsible for a "dissipationless" longitudinal current
channel of the bulk. In this study, we verify that intertwined these two
effects can be measured in Shubnikov-de Haas (SdH) quantum oscillations, where
a double-peak structure of the SdH oscillation appears to cause a kink in the
Landau fan diagram. We examine three different cases which cover all possible
experimental situations of external electric/magnetic fields and identify the
experimental condition for the existence of the double-peak structure. We claim
that interplay of the orbital magnetic moment and the chiral magnetic effect in
SdH quantum oscillations is an interesting feature of the Weyl metal state.
