This chapter presents two tools for use in the field to aid in differentiation and identification of volcanic deposits emplaced on dry land: a quick-reference key for deposit identification (Table 1) and a set of tables summarizing all the evaluation criteria for each deposit type, including each type of volcanic wet flow and the three other types of deposits at volcanoes containing volcanic particles (Tables 2, 3, 4, 5, 6, 7, and 8). Assessment of the physical characteristics of deposits should be carried out at different scales in the field, and field observations can benefit from additional particle-size analysis in the laboratory. If appropriate, field measurement of thermoremanent magnetic orientation of large in-situ clasts can provide additional insight. It is important to note that the identification criteria used in this book are characteristics best preserved in fresh (unaltered) deposits but may be preserved in many older, altered deposits, as well.
