It is possible that small droplets of quark matter, larger than ordinary nuclei, exist in nature. These "nuggets" could be present in the Universe and provide one explanation for the dark matter. This suggestion provides matter fluctuations at galaxy scale and thus leads to a natural explanation for the formation of galaxies from primordial fluctuations. The question is whether the predicted primordial nucleosynthesis of the light elements could, in the presence of nuggets, still be consistent with the tight observational constraints. The authors examine the possibility of obtaining the observed yields of the light elements in an Ω = 1 baryonic universe where a sizeable fraction of the matter is in the form of quark nuggets.
