• Beta Hunt Geological Report on the Kambalda Dome and Gold , - Know More

  This sediment layer is iron rich and it is the iron content contained within the sediment that caused the pockets of coarse gold to form The sediment layer is relatively thin, less than 5 meters thick, so the coarse gold would be located primarily where the shears and faults intersect this sediment layer...

• Sedimentary Rocks - Know More

  Iron and silica, , One of the most obvious features of sedimentary rocks and sediment is the layered structure which they exhibit , The presence of mudcracks indicates that the sediment was exposed at the surface shortly after deposition, since drying of the sediment would not occur beneath a body of water Raindrop Marks - pits or tiny ....

• Sediment transport - Know More

  Sediment transport is the movement of solid particles , typically due to a combination of gravity acting on the sediment, and/or the movement of the fluid in which the sediment is entrained Sediment transport occurs in natural systems where the particles are clastic rocks sand, gravel, boulders, etc , mud, or clay the fluid is air, water, or ice and the force of gravity acts to move the ....
