Fossil compaction is not a process which forms metallic ore whereas the other three ie placer processes, hydrothermal fluids and igneous processes all can help to form metallic ores. Placer does it by stream transport and separation of the heavy gold, and the fluids can carry metals and deposit them in the fractures in the solid rock and igneous processes like fractional crystallization can form a concentration of metallic ores also.
<span> sediment formed from the weathering and erosion of rock. Over time, sediment accumulates in oceans, lakes, and valleys, eventually building up in layers and weighing down the material underneath. This weight presses the sediment particles together, compacting them. Water passing through the spaces in between the particles helps to cement them together even more. This process of compacting and cementing sediment forms sedimentary rock</span>
