Yes, in the mathematical definition of the geometric mean (the nth root of a product), a single zero will cause the geometric mean itself to be zero. In statistics, the data must be strictly positive. When the data are positive, an equivalent definition is the mean of the logged values: (1/n) Sum of log(x_i).
