  Several models of baryo(lepto)-genesis that give rise to large
inhomogeneities in the composition of the universe are presented. In
particular, a variation of primordial abundances of light elements by the
factor 2-5 at large distances is predicted. A cosmological model of baryonic
island is considered. Creation of domains with very large baryon and antibaryon
number is described. Such domains mostly collapsed into primordial black holes
that could be the dominant part of (non-standard) cosmological cold dark matter
with a widely dispersed mass spectrum. A non-collapsed part of these bubbles
might make clouds of matter or antimatter with an enriched abundances of
metals. A mechanism for creation of such exotic objects can be realized by
mixed order phase transitions induced by the inflaton field.
