  The abundance of alpha elements and iron in stars of globular clusters shows
the composition of the gaseous medium, in which they have been formed. In the
present paper, we discuss a possibility to consider dense clouds of
circumgalactic gas (partial Lyman limit systems and Lyman limit systems)
observed in the 100 - 130 kpc neighbourhood of galaxies at redshifts of
0.1<z<1.1 as being the residual parts of clouds, in which globular clusters
have been formed. Conclusions have been drawn based on statistical analysis of
the abundance of magnesium and iron in globular clusters and in circumgalactic
clouds and on the spatial location of objects of both types.
