A two-qubit Heisenberg XXX spin chain is considered in the presence of Dzyaloshinskii-Moriya (DM) and Kaplan-Shekhtman-Entin-Wohlman-Aharony (KSEA) interactions. The discord-like quantifiers, specifically, those of the Sharma-Mittal, Renyi discord and Tsallis quantum discord, are used to evaluate Non-classical thermal correlations in this system. Their explicit analytical expressions are found as a function of the thermal state of the studied system. In addition, the behavior of these quantifiers is discussed versus a number of different parameters present in the system. It is shown that the DM and KSEA interactions have a significant effect on the quantum correlations present in the system, while the temperature tends to reduce them, and we deduce specifically that the Sharma-Mittal quantum discord is a faithful quantifier.
