The ARGO-YBJ experiment, installed at the YangBaJing Cosmic Ray
Laboratory (4300 m a.s.l., Tibet, P.R. China), is an air shower
array exploiting the full coverage approach at very high altitude.
Signals from each RPC are picked-up by strips 6 cm wide and 62 cm
long, thus allowing to sample the Extensive Air Showers (EAS) with
an unprecedented granularity. In order to extend the dynamic range
up to PeV energies, a charge read-out has been implemented by
instrumenting every RPC also with two large size pads of dimension
140$\times$125 cm$^2$ each. As a consequence, for the first time
the topological characteristics of EAS and the geometric structure
of shower cores can be investigated with a great detail over more
than two energy decades, up to the knee region.
In this work we report a measurement of the lateral distribution
of charged particles in EAS performed by the ARGO-YBJ carpet. The
sensitivity to the primary mass at energies higher than 10$^{14}$
eV will be discussed. A procedure to select events characterized
by unusual distributions of charged particles (multicore events,
aligned structures, "halo" events, etc.) will be also presented.
