jj^ A controls on permeability, ground water flow, and oxidation; and other deposit types with similar environmental geology characteristics. Some of the environmental models presented in this compilation also provide available empirical data on environmental signatures that: (1) are present prior to mining in soil, stream sediment, and ground and surface water; (2) result from mining and mineral processing (mine drainage water, mine wastes, mill tailings and tailings water, and heap leach solutions), and (3) result from smelting (smelter slag and stack emissions). Environmental signatures include information concerning the elemental suites and their likely concentration in water, waste, and soil, etc., and the ease with which the elements can be liberated into the environment (their "geoavailability"). Empirical data from well characterized sites is lacking for some deposit types; potential environmental signatures for these deposit types can be extrapolated from similar deposits for which data are available. The models also include information, when available, on engineering and other types of processes that have been or likely can be used successfully to avoid, minimize, and remediate environmental signatures summarized in the models. The geoenvironmental model for each deposit type is organized as follows: I. SUMMARY OF RELEVANT GEOLOGIC, ENVIRONMENTAL, AND GEOPHYSICAL INFORMATION A summary of geoenvironmentally relevant information for each model includes: A. Deposit type geology B. Examples of deposits of this type C. Spatially or genetically related deposit types, listed by model name and number. In many mining districts, more than one deposit type may be present; each deposit type may have different associated geoenvironmental effects or concerns D. Potential environmental considerations: This section is designed to summarize environmental signatures that may be associated with each deposit type as well as some of the important geologic characteristics that affect these signatures E.
