We present the results of our spatially resolved investigation into the interplay between the ages of the stellar populations and the kinematics of the warm ionized outflows in the well-studied type II quasar Markarian 34 (Mrk 34). Utilizing integral field spectroscopy data, we determine the spatial distribution of the young stellar population (YSP; t_YSP < 100 Myr) using spectral synthesis modelling. We also employ the [O III] λ5007 emission line as a tracer of the warm ionized gas kinematics. We demonstrate a spatial correlation between the outer edges of the blue side of the outflow and an enhancement in the proportion of the YSP flux, suggesting that the outflow is responsible for triggering star formation in this region. In regions with more highly disrupted gas kinematics, we find that the proportion of YSP flux is consistent with that found outside the outflow region, suggesting that the increased disruption is preventing a similar enhancement in star formation from occurring. Our analysis suggests that Mrk 34 is an example of quasar-driven outflows simultaneously producing both 'positive' and 'preventive' feedback, further demonstrating the complex nature of the relationship between quasars and their host galaxies.
