  For a given Coleman family of modular forms, we construct a formal modeland
prove the existence of a family of Galois representations associated to the
Colemanfamily. As an application, we study the variations of Iwasawa $\lambda$-
and $\mu$-invariants of dualfine (strict) Selmer groups over the cyclotomic
Zp-extension of Q in Coleman families ofmodular forms. This generalizes an
earlier work of Jha and Sujatha for Hida families.
