查询词典 sediment

Ore source of celestite mineralization system is complex in this area. Weathering and erosion of the floor of the basin and the mountain around the basin, evaporite sediment in the earlier, deep water, Mesozoic and Cenozoic volcanism can provide the strontium. In particular, serving as initial ore source, oil-field brine supplies the majority of strontium.
