Cave sediments were differentiated based on color, grain size, and general composition. Sediments were mapped and digitally drawn onto the plan and profile cave maps. The classification and descriptions of mapped sediments are shown in Table 1. The distribution of sediments were mapped onto cave profiles Ato determine the vertical... 

Systems now available allow simultaneous acquisition of maps for several different elements. Digital maps with colors assigned for each element permit a more rapid and detailed analysis. Superposition of the color maps is useful in determining associations between elements. This technique is more than simple elemental mapping and approaches more definitive compositional studies. It is important for beam sensitive specimens because of its speed. Multiple maps may be obtained in the time previously used for mapping a single element.
