  We examine thermal quantum correlations characterized by Measurement-Induced
Nonlocality (MIN) in an infinite spin-1/2 Ising-Heisenberg spin chain with
Dzyaloshinskii-Moriya (DM) interaction. We evaluate MIN analytically in the
thermodynamic limit using the transfer matrix approach and show that the MIN
and its first-order derivative may spotlight the quantum criticality and
quantum phase transition (QPT). We observe that the DM interaction reduces the
role of anisotropy parameter in initiating QPT. Further, the DM interaction
also induces the nonlocality in the system if the spins are unentangled and
greatly enhances the quantum correlations if the spins are correlated. The
impact of the magnetic field and temperature on quantum correlations is also
brought out at a critical point.
