Geological control of dredging operation on placer deposits, Billiton, Indonesia
Maps of tin distribution can be used as exploration aid; fine grained cassiterite was washed into bottom ore layer of coarse angular debris at time that sand was deposited on top of this layer; coarse grained cassiterite and coarse quartz probably were deposited in earlier period; method of dredging out area of proven ore.
