Calcretes are useful to the earth scientist involved in reconstructing ancient environments, palaeoclimates and palaeographics, and they may also reveal details of soil biota and chemistry. Over the last two decades the journal Sedimentology has published a number of articles on this subject and a compilation of them is presented here.
