Minerals In Coal
Coal, Kentucky Geological Survey, University of Kentucky
Minerals in coal can be divided into two broad categories: (1) minerals that originated in the original coal-forming peat, termed syngenetic or primary minerals, and (2) diagenetic or secondary minerals, which were introduced into the coal, remobilized in the coal, or transformed from other minerals in the coal at any time after the original .
The Rock - COAL - Amethyst Galleries' Mineral Gallery
Some people consider coal to be a metamorphic rock, the result of heat and pressure on organic sediments such as peat. But most sedimentary rocks undergo some heat and pressure, and coal's intimate association with "normal" sedimentary rocks and its mode of formation usually keep low grade coal in the sedimentary classification system.
