In this paper, we report our high-resolution($0^{\prime\prime}.20\times0^{\prime\prime}.14$ or $\sim$$70\times49$ pc)observations of the CO(6-5) line emission, which probes warm and densemolecular gas, and the 434 $\mu$m dust continuum in the nuclear region of NGC7130, obtained with the Atacama Large Millimeter Array (ALMA). The CO line anddust continuum fluxes detected in our ALMA observations are $1230\pm74$ Jy kms$^{-1}$ and $814\pm52$ mJy, respectively, which account for 100% and 51% oftheir total respective fluxes. We find that the CO(6-5) and dust emissions aregenerally spatially correlated, but their brightest peaks show an offset of$\sim$70 pc, suggesting that the gas and dust emissions may start decoupling atthis physical scale. The brightest peak of the CO(6-5) emission does notspatially correspond to the radio continuum peak, which is likely dominated byan Active Galactic Nucleus (AGN). This, together with our additionalquantitative analysis, suggests that the heating contribution of the AGN to theCO(6-5) emission in NGC 7130 is negligible. The CO(6-5) and theextinction-corrected Pa-$\alpha$ maps display striking differences, suggestiveof either a breakdown of the correlation between warm dense gas and starformation at linear scales of $<$100 pc or a large uncertainty in ourextinction correction to the observed Pa-$\alpha$ image. Over a larger scale of$\sim$2.1\,kpc, the double-lobed structure found in the CO(6-5) emission agreeswell with the dust lanes in the optical/near-infrared images.
