The mineralogy and surface texture of the silica sands of Black River, Jamaica: Its importance as a guide to future exploration of silica sand deposits in Jamaica
Proceedings of the Caribbean Academy of Sciences
Date of Publication
Commercial quantities of silica sand are mined in the Black River area. The occurrence of these deposits is unique in that they are found only in this area of Jamaica. The model for the origin of the silica sands has important implications for any future exploration of these sands in Jamaica. The marine microtextures obtained during the movement of the sand along the south coast indicate that silica sands may still remain on the shelf, but buried below younger magnetic sands. The movement of quartz-rich sand by wind action onto the low-lying plains of Black River suggests that there is sand of a similar composition buried a few meters below the present surface in other sections of the Black River Plain, and in other flat-lying plains along Jamaica's south coast.....
