Host rocks include both mafic and felsic volcanic rocks or their volcaniclastic equivalents, silica-rich chemical sediments, and locally developed carbonate horizons. Some host rocks display variably preserved relict volcanic and (or) sedimentary textures, but the majority are metamorphic rocks having original textures and mineralogies substantially changed. In addition, many host rocks experienced significant premetamorphic chemical alteration that further obscures their origins. For these reasons, the \"Host rock lithology\" column in table 1 first lists a metamorphic rock description and them, in parentheses, suggests a possible volcanic or chemical-sediment protolith.</p>\n<p>With the exception of the Pecos mine and a subsurface deposit partially outlined by recent drilling at Jones Hill, New Mexico occurrences shown on this map do not exhibit enough of the classic features of volcanogenic massive-sulfide deposits to make their classification (or origins) unequivocal. Nonetheless, these occurrences are included because they might be genetically, spatially, chronologically, or in some combination of ways related to volcamogenic massive-sulfide-forming systems and are therefore deserving of further study.</p>\n<p>The following two sections 1) outline the general geologic setting and character of New Mexico&rsquo;s Proterozoic volcanic terranes, which host volcamogemic massive-sulfide occurrences, and 2) describe the general features of two occurrences--the Pecos mine and Jones Hill--which display the most complete and convincing collection of \"classic\" volcanogenic massive-sulfide features of any of the New Mexico examples.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/mf1853A","usgsCitation":"Robertson, J.M., Fulp, M., and Daggett, M., 1986, Metallogenic map of volcanogenic massive-sulfide occurrences in New Mexico: U.S. Geological Survey Miscellaneous Field Studies Map 1853, Plate: 46.89 x 30.35 inches, https://doi.org/10.3133/mf1853A.","productDescription":"Plate: 46.89 x 30.35 inches","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":327462,"rank":1,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1853-A/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":326128,"rank":2,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/mf1853A.JPG"}],"scale":"0","country":"United States","state":"New Mexico","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -109,31 ], [ -109,37 ], [ -103,37 ], [ -103,31 ], [ -109,31 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4fe4b07f02db6286fd","contributors":{"authors":[{"text":"Robertson, J.

These efforts have improved our knowledge of the geologic history, general tectonic setting, and patterns of modern seismicity (see McKeown and Pakiser, 1982) in the New Madrid seismic zone. Identifying and characterizing the specific structures that may be responsible for the seismicity is the focus of continuing research. Unfortunately, these structures are buried by the veneer of poorly consolidated Upper Cretaceous and Tertiary sediments that overlie competent rocks in the embayment. In such a geologic setting, seismic-reflection profiling is one of the most valuable techniques available to obtain useful information on the distribution of faults, and on the local and regional structure.</p>\n<p>Three major seismic-reflection programs have been conducted by the USGS in the New Madrid seismic zone. The first program consisted of 32 km of conventional Vibroseis profiling designed to investigate the subsurface structure associated with scarps and lineaments in northwestern Tennessee (Zoback, 1979). A second, more extensive Vibroseis program collected about 250 km of data from all parts of the New Madrid seismic zone in Missouri, Arkansas, and Tennessee (Hamilton and Zoback, 1979, 1982; Zoback and others, 1980). The profiles presented here are part of the third program that collected about 240 km of high-resolution seismic-reflection data from a boat along the Mississippi River between Osceola, Ark., and Wickliffe, Ky. (fig. 1). The data for profiles A, B, C, and D were collected between river miles 839-1/2 and 850-1/2 from near the Interstate-155 bridge to upstream of Caruthersville, Mo. (fig. 2). Profiles on this part of the river are important for three reasons: (1) they connect many of the land-based profiles on either side of the river, (2) they are near the northeast termination of a linear, 120km-long, northeast-southwest zone of seismicity that extends from northeast Arkansas to Caruthersville, Mo. (Stauder, 1982; fig. 1), and (3) they cross the southwesterly projection of the Cottonwood Grove fault (fig. 1), a fault having a substantial amount of vertical Cenozoic offset (Zoback and others, 1980).</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/mf1863","isbn":"0607817208","usgsCitation":"Crone, A.J., Harding, S., Russ, D.P., and Shedlock, K.M., 1986, Seismic-reflection profiles of the New Madrid seismic zone-data along the Mississippi River near Caruthersville, Missouri: U.S. Geological Survey Miscellaneous Field Studies Map 1863, 4 Plates: 40.82 x 57.37 inches or smaller, https://doi.org/10.3133/mf1863.","productDescription":"4 Plates: 40.82 x 57.37 inches or smaller","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":326124,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/mf1863.JPG"},{"id":327013,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1863/plate-2.pdf"},{"id":327012,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1863/plate-1.pdf"},{"id":327014,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1863/plate-3.pdf"},{"id":327015,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1863/plate-4.pdf"}],"scale":"90000","country":"United States","state":"Missouri","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -89.73333333333333,36.084722222222226 ], [ -89.73333333333333,36.25 ], [ -89.56805555555555,36.25 ], [ -89.56805555555555,36.084722222222226 ], [ -89.73333333333333,36.084722222222226 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9be4b07f02db65e0df","contributors":{"authors":[{"text":"Crone, A.
