Volcanic-Sedimentary Ores



Many ore deposits associated with vocanic rocks show sedimentary features, and research on modern examples reveals that formation of the ore is partly contemporaneous with deposition of the enclosing sediment. Thus, these ores are partly syngenetic, but would not be classed as sedimentary by most geologists. Such deposits easily warrant a separate book; in this chapter I will restrict the discussion mostly to the sedimentary portions of the deposits and how they compare with purely sedimentary accumulations. For a long review, one with much attention to Precambrian examples, which are neglected here, see Franklin and others (1981). Two other good summaries, which provide more information on the high-temperature part of these systems, are Klau and Large (1980) and Finlow-Bates (1980).
