A high acid (low pH) environment will stop the formation of carbonates. Acid dissolves carbonates. For example, sulphuric acid will dissolve limestone.
It is too easy to relate this question with global warming, that's why I chose this answer.

If you consider reef-rock as an organic rock, then a sudden cooling of the environment would kill the reef and stop further development.
Coal, on the other hand, is composed of carbon of organic (mainly plant) material. It is deposited and then buried, compacted, and turned to almost pure carbon. If a forest is exhumed from water before burial (due to uplift or lowering of sea level it will not become buried, hence will not be turned to coal.

A change in sea level. This happened many times in the past, and is basically why coal is found in narrow bands between other layers of rocks.
