Abstract We present the first detailed chemical analysis from APOGEE-2S observations of stars in six regions of recently discovered substructures in the outskirts of the Magellanic Clouds extending to 20$^{\circ}$ from the LMC center. We also present, for the first time, the metallicity and $\alpha$-abundance radial gradients of the LMC and SMC out to 11$^{\circ}$ and 6$^{\circ}$, respectively. Our chemical tagging includes 13 species including light, $\alpha$, and Fe-peak elements. We find that the abundances of all of these chemical elements in stars populating two regions in the northern periphery — along the northern “stream”-like feature — show good agreement with the chemical patterns of the LMC, and thus likely have an LMC origin.
