We perform a mutual analysis of the topological and chiral vacuum structure of four-dimensional QCD on the lattice at finite temperature. Concerning the topological sector, correlation functions between the distributions of color magnetic monopoles in the maximum Abelian gauge and the densities of topological charge are computed. An enhanced probability for monopoles inside the core of an instanton is found on the gauge field average and in specific configurations. In the chiral sector, clear evidence is found that monopole loops and instantons are locally correlated with the quark condensate. {copyright} {ital 1997} {ital The American Physical Society}
