We use high-resolution three-dimensional adaptive mesh refinement simulationsto investigate the interaction of high-redshift galaxy outflows with low-massvirialized clouds of primordial composition. While atomic cooling allows starformation in objects with virial temperatures above $10^4$ K, "minihaloes"below this threshold are generally unable to form stars by themselves. However,these objects are highly susceptible to triggered star formation, induced byoutflows from neighboring high-redshift starburst galaxies. Here we conduct astudy of these interactions, focusing on cooling through non-equilibriummolecular hydrogen (H$_2$) and hydrogen deuteride (HD) formation. Tracking thenon-equilibrium chemistry and cooling of 14 species and including the presenceof a dissociating background, we show that shock interactions can transformminihaloes into extremely compact clusters of coeval stars. Furthermore, theseclusters are all less than $\approx 10^6 M_\odot,$ and they are ejected fromtheir parent dark matter halos: properties that are remarkably similar to thoseof the old population of globular clusters.
