Attribute:
Attribute_Label: deptype
Attribute_Definition:
Deposit type.

Type of deposit: Felsic; Bimodal-Mafic; or Mafic. These VMS-deposit types were adopted on the basis of simplicity of use, greater relevance to map units, and our grade and tonnage models. The three VMS-deposit types are compared to previous VMS-classification schemes in table 1 of the report. The felsic type deposits are hosted in a dominantly felsic to intermediate volcanic sequence and includes those formerly classified as kuroko-type deposits (Singer, 1986b; Singer and Mosier, 1986b). This type includes deposits hosted in a continuous felsic to intermediate volcanic sequence, a bimodal-felsic volcanic sequence, or a siliciclastic-felsic volcanic sequence. The bimodal-mafic type deposits are hosted in a dominantly mafic (andesite to basalt) volcanic sequence associated with greater than 10 percent felsic (rhyolite to rhyodacite) volcanic units. Dacite or andesite rocks are either rare or absent. This deposit type includes kuroko-type (Singer, 1986b; Singer, and Mosier, 1986b), Noranda-type (Morton and Franklin, 1987; MacGeehan and MacLean, 1980), and Urals-type (Prokin and Buslaev, 1999) deposits of previous classifications. The mafic type deposits are hosted in a dominantly mafic (andesitic basalt to basalt) volcanic sequence; some are associated with gabbro, diabase, and ultramafic rocks of more complete ophiolite sequences. Felsic rocks are rare or absent. This deposit type include the Cyprus-type and Besshi-type deposits (Cox, 1986; Singer, 1986a; Singer, 1986c; Singer and Mosier, 1986a). In a few cases, it was not possible to classify a deposit for lack of crucial information, such as the composition of volcanic rocks or the proportions of felsic and mafic volcanic rocks in bimodal volcanic sequences.

Attribute:
Attribute_Label: lithotect
Attribute_Definition:
Lithotectonic setting.

A classification of the deposit using one or more of eight lithostratigraphic associations in tectonic settings. When the lithotectonic setting was undetermined, it was coded as 'Unclassified.' The lithotectonic settings are defined as follows: 1. Siliciclastic-felsic in a mature epicontinental arc. Found in epicontinental backarc settings, the stratigraphy consists of continent-derived sedimentary rocks (~80%) and felsic volcaniclastic rocks, with minor flows domes, and their intrusive equivalents (~25%), mafic (tholeiitic to alkaline) flows, sills, and minor volcaniclastic rocks (~10%). Mafic volcanic rocks and argillaceous and chemical sedimentary rocks are typically in the hanging wall. 2. Bimodal-felsic in an epicontinental arc. Found in rifted continental margins and incipient (suprasubduction related) arcs, the stratigraphy consists of submarine felsic volcanic rocks (35-70%), basalt (20-50%), and terrigenous sedimentary strata (~10%). 3. Bimodal-felsic in an oceanic arc. Found in oceanic backarc rifts, the stratigraphy consists of submarine felsic volcanic rocks (50-70%), mafic volcanic rocks (20-50%), and sedimentary rocks (up to 30%). 4. Bimodal-mafic in an epicontinental arc. Found in epicontinental backarc settings, the stratigraphy is dominated by mafic volcanic rocks (pillowed and massive basaltic flows and pyroclastic rocks), with minor felsic volcanic rocks (flows, pyroclastic rocks, domes) and volcaniclastic rocks (<25%), and subordinate terrigenous sedimentary rocks. 5. Bimodal-mafic in an oceanic arc. Found in incipient-rifted arcs above intraoceanic subduction zones. The stratigraphy is dominated by basalt pillowed and massive flows and volcaniclastic rocks with minor felsic flows, volcaniclastic rocks, and domes (<25%), and subordinate terrigenous sedimentary rocks. 6. Mafic in a primitive oceanic backarc. This stratigraphy includes mature intraoceanic backarcs and transform fault settings, dominated by MORB-boninitic and tholeiitic successions of pillowed and massive basalt flows, minor felsic flows and domes, including subvolcanic plagiogranite and icelandite, minor ultramafic flows and intrusions, synvolcanic mafic dikes and sills (up to 50%), and prominent altered mafic synvolcanic intrusions. Sedimentary rocks are minor (<10). Less common is alkaline basalt (locally bimodal) in oceanic island or late-stage continental backarc seamount environments. 7. Mafic in a midoceanic ridge. The stratigraphy consists of dominantly massive and pillowed basalt flows associated with synvolcanic mafic dikes or sills, ultramafic flows, and intrusions, typically part of an ophiolite sequence. Felsic volcanic and sedimentary rocks are rare (<5%). This mafic setting is distinguished from the primitive oceanic backarc setting by the absence of an associated arc. 8. Pelite-mafic in a mature oceanic backarc. This stratigraphy includes mature oceanic backarc and sediment-covered midoceanic ridge and transform fault settings. The stratigraphy consists of basalt and pelite, in equal proportions, to pelite-dominated successions, with mafic sills (up to 25%), felsic flows, sills, domes, and volcaniclastics (<5% or absent), and carbonaceous argillite with subordinate siltstone, wacke, and sandstone. Because of the difficulty of recognizing the specific lithotectonic setting for each of the VMS deposits in this report, the lithotectonic setting classification should be viewed as preliminary. Many of the volcanic belts have not been sufficiently investigated to determine whether they were formed in an epicontinental (sialic) or an oceanic (ensimatic) environment. Furthermore, the tectonic settings of some belts are not in agreement among investigators, such as at Joma, Norway (Stephens and others, 1984). Lithogeochemical data, particularly for the rare earth elements, are not available for many volcanic rocks that would allow classification of paleotectonic environments using element-ratio discriminant diagrams.

Mineralogy.

Reported minerals listed in alphabetical order. We attempted to tabulate specific mineral names when available, but, in some cases, when specific minerals were not reported, group names were included, such as 'carbonates' or 'sulfosalts.' Most ubiquitous rock forming minerals, such as feldspar, calcite, and quartz, are not included. Native metals are reported with just their element names, such as gold, silver, bismuth, and platinum. For consistency, attempts were made to eliminate synonyms, such as covelline, black jack, niccolite, which were replaced by covellite, sphalerite, nickeline, respectively. Some solid solution series, such as 'tennantitetetrahedrite,' were entered as separate mineral end members of the series, such as 'tennantite, tetrahedrite'. Chemical formulas were included for some unnamed species or rarer minerals. Because of the varied levels of reporting mineralogy, most of the deposits in this report display an incomplete list of minerals. Textual values of no more than 63 characters.

Some rocks that are important in exploration for VMS deposits, such as exhalite beds (for example, chert, jasperoid, or siliceous bed), may not have been recorded if they were not recognized by the investigators. Textual values of no more than 171 characters.
