  Based on the fact that the constituent quark model reproduces the recent
lattice result on baryon-baryon repulsion at short distance and that it
includes the quark dynamics with confinement, we analyze to what extent the
quarkyonic modes appear in the phase space of baryons as one increases the
density before only quark dynamics and hence deconfinement occurs. We find that
as one increases the baryon density, the initial quark mode that appears will
involve the $d(u)$-quark from a neutron (proton), which will leave the most
attractive ($ud$) diquark intact.
