| Abstract | The most widely used ore in the world's phosphate industry is sedimentary phosphate rock, or phosphorite, in which the apatite mineral series is prominent. The sedimentary phosphate minerals probably
form during diagenetic phosphatization of sediments in certain shallow-marine environments near loci of upwelling deep-sea water. Hypothetical models of various sedimentological-tectonic conditions that apparently occurred during phosphate deposition
have been used in delineating promising areas for prospecting. In this paper, several models are drawn from descriptions of known phosphoritic regions, and a genetic scheme of classification is proposed. Canada has a well-developed phosphate industry
although no ore is mined in this country. Phosphorite is reported, however, from beds of a wide range of ages and it should be possible, using criteria derived from the models for deposition of marine apatite, to delineate favourable sites for
prospecting and testing. |
