  We establish a Chung-type law of the iterated logarithm and the exact local
and uniform moduli of continuity for a large class of anisotropic Gaussian
random fields with a harmonizable-type integral representation and the property
of strong local nondeterminism. Compared with the existing results in the
literature, our results do not require the assumption of stationary increments
and provide more precise upper and lower bounds for the limiting constants. The
results are applicable to the solutions of a class of linear stochastic partial
differential equations driven by a fractional-colored Gaussian noise, including
the stochastic heat equation.
