Element abundances in Mississippi Mud. These are the numbers from an analysis of river mud I collected during the New Orleans workshop in November. I use a machine that measures the abundance of elements in bulk samples of soils and sediments and during some machine testing this week, I remembered I had this sample. The top figure is for trace elements in units of ppm (parts per million) and the lower one for major elements as % abundance. Major elements usually represent the dominant geology of a catchment (why not colour RWB, I thought) and trace elements the local geology (hence Choctaw flag colours). The size of the rectangles are proportional to the elements abundance. Sediment geochemistry, geopolitics and tribal entities are not very often combined.
