This is one of many related papers that were included in the 1978 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

Lindgren at the start of the 20th century. For most of the century, geological investigation focused on mineralization and the complex suite of Eocene porphyritic intrusive stocks and dikes in the area. Very little attention was directed at the regional structural and stratigraphic relationships in the overlying, and largely unmineralized Tertiary volcanic rocks. From the beginning, geologists have understood that supergene enrichment played a critical role in making the Morenci district a world class porphyry copper deposit (Lindgren, 1905a). For much of the past 90 years, enrichment was thought to have occurred during two phases of exposure and erosion: pre-volcanic and post-volcanic (Lindgren, 1905a; Moolick and Durek, 1966; Langton, 1973; North and Preece, 1993).

August 2009 Arizona Geological Survey Open-File Report 09-05 (OFR-09-05), version 1.0 Disturbed areas (Holocene) - Areas distrubed by human activity; embackments, dams, dumps.

Gila Conglomerate (Miocene) -Boulder-cobble-pebble, clast-supported conglomerate and pebbly sandstone. Conglomerate occurs in fairly massive to very thick-bedded units with stratification defined by grain-size variations. Clasts are sub-angular to sub­ rounded , but also range to well-rounded. Assemblages range from monomict to oligomict with a wide variety of possible clasts, all derived from local sources. Clasts, in general order of abundance are: phenocryst-rich ash-flow tuff, arkosic sandstone, argillite, quartz sandstone and quartzite, limestone, andesitic volcanics, and two kinds of granitoid (Proterozoic, and late Cretaceous). Each of these are locally very abundant. Unit of North Canyon (Miocene Gila Group) - Oligomict to polymict conglomerate. Clasts of arkose and ash-flow tuff dominate in most areas, but this conglomerate also contains clasts of white porphyry (ranging from phenocryst-rich quartz-phyric to feldspar-phenocryst-poor), limestone, quartzite, and granodiorite. Unit of Adobe Tank (Miocene Gila Group) - Monomict to oligomict conglomerate dominated by clasts of arkose (Bisbee Group), and ash-flow tuff (rhyolite of Mt Fagan) in the west. To the east this conglomerate also contains, locally, light-colored granitoid clasts that match the Empire Mts Granite (Upper Cretaceous).

  • Brachiopods from the Mobarak Formation, North Iran
    GeoArabia, 2011, v. 16, no. 3, p. 129-192 Gulf PetroLink, Bahrain Tournaisian (Mississippian) brachiopods from the Mobarak Formation, North Iran Maryamnaz Bahrammanesh, Lucia Angiolini, Anselmo Alessandro Antonelli, Babak Aghababalou and Maurizio Gaetani ABSTRACT Following detailed stratigraphic work on the Mississippian marlstone and bioclastic limestone of the Mobarak Formation of the Alborz Mountains in North Iran, forty-eight of the most important brachiopod taxa are here systematically described and illustrated. The ranges of the taxa are given along the Abrendan and Simeh Kuh stratigraphic sections, located north of Damgham. The examined brachiopod species date the base of the Mobarak Formation to the Tournaisian, in absence of age-diagnostic foraminifers. Change in brachiopod settling preferences indicates a shift from high energy, shallow-water settings with high nutrient supply in the lower part of the formation to quieter, soft, but not soppy substrates, with lower nutrient supply in the middle part of the Mobarak Formation. Brachiopod occurrence is instead scanty at its top. The palaeobiogeographic affinity of the Tournaisian brachiopods from North Iran indicates a closer relationship to North America, Western Europe and the Russian Platform than to cold-water Australian faunas, confirming the affinity of the other biota of the Alborz Mountains. This can be explained by the occurrence of warm surface-current gyres widely distributing brachiopod larvae across the Palaeotethys Ocean, where North Iran as other peri- Gondwanan blocks acted as staging-posts. INTRODUCTION The Mississippian Mobarak Formation of the Alborz Mountains (North Iran) has been recently revised by Brenckle et al. (2009) who focused mainly on its calcareous microfossil biota and refined its biostratigraphy, chronostratigraphy and paleogeography.

EASTON University of Southern California, Los Angeles 7, California ABSTRACT—Seven species of rugose corals are described from Permian (mostly Leonard Series) strata in the Basin and Range Province of Nevada and California. Caninia trojana, Lithostrotionella mokomokensis, Lithostrotionella dilatata, Diphy- phyllum connorsensis, Thysanophyllum princeps, Lonsdaleia illipahensis, and Lonsdaleia cordillerensis are named. The corals occur in thick successions of com- monly cyclical alternations of limestone and sandstone near the eastern margin of the Cordilleran geosyncline. Local distribution and biostromal development can be used in subdividing and mapping the Permian strata of east-central Nevada.
