Some Scolytidae From the Sierra Madre Occidental in Mexico
The Canadian Entomologist, 1966AbstractA survey of the insect fauna in a part of the Sierra Madre Occidental in Mexico was made in 1964 by a party of nine entomologists from the Canada Departments of Agriculture and Forestry. Approximately 50 species of Scolytidae in 20 genera were collected on this expedition and are listed with host relationships and distribution where possible. A

Notes on Obsidian Sources of the Southern Sierra Madre Occidental
Ancient Mesoamerica, 1993AbstractRecent fieldwork has identified a previously unknown obsidian source area in southern Zacatecas and northern Jalisco. Evidence of prehistoric use of surface gravel and nodule outcrops in the Huitzila-La Lobera source area includes raw-material extraction and the production of cores, large blade blanks, rough bifaces, and other artifacts ...

Tectonomagmatic Pulses and Multiphase Mineralization in the Sierra Madre Occidental, Mexico
2020The material covered over this six-day field trip explores the regional stratigraphy, tectonic setting, and mineral deposits of the central Sierra Madre Occidental and western part of the Mesa Central in Mexico. The course builds on similar field trips held in 1997, 2003, and 2014, adding updates of the geology based on new studies and opening of new ...

Biodiversity and biogeography of the avifauna of the Sierra Madre Occidental, Mexico
Biodiversity and Conservation, 2014The Sierra Madre Occidental (SMOc) is located in the boundary between the Nearctic and Neotropical regions, area which has been considered as a complex transition zone. We analysed biogeographic patterns of its resident avifauna, including species richness, endemism, and biotic regionalization by analysing presence-absence matrices of 148 species of ...

Northern Sierra Madre Occidental Gold-Silver Mines, Mexico
2010Abstract The Mulatos district is a volcanic-hosted, advanced argillic, gold enargite system of late Oligocene age, located in the northern Sierra Madre Occidental volcanic province of Sonora, Mexico. Hypogene mineralization is associated with rhyodacite domes and major faults. Gold is associated with pyrite ± enargite in distinct pods of

New Species of Lampropeltis (Serpentes: Colubridae) from the Sierra Madre Occidental, México
Journal of Herpetology, 2005We describe a new species of Lampropeltis from the Pacific versant of the Sierra Madre Occidental in western Mexico based on external morphology, scutellation, and molecular data. This species appears to be closely related to Lampropeltis pyromelana and Lampropeltis mexicana.

ARCHITECTURAL PATTERNS ALONG THE RIO TARAISES, NORTHERN SIERRA MADRE OCCIDENTAL, SONORA
KIVA, 2004The prehistory of the northern Sierra Madre Occidental of Mexico is poorly understood. This article reviews previous research in the region and describes the archaeology of the Rio Taraises (Lister 1958). My principal interest is the cliff-dwellings Cueva Bringas and Cueva el Aguaje, which were the subject of a recent archaeological project ...

Tertiary volcanism and caldera development near Durango City, Sierra Madre Occidental, Mexico
Geological Society of America Bulletin, 1978Near Durango City, older andesites are overlain by approximately 800 m of rhyolitic volcanic rock, mostly ash-flow tuff of Oligocene age. The rhyolite is unconformably overlain by a few tens of meters of late Miocene basalt in the highlands west of Durango City and by Quaternary basalt and gravel in the Guadiana Valley. By 32 m.y.

Contributions to Mineralogy and Petrology, 1980
The mid-Tertiary ignimbrites of the Sierra Madre Occidental of western Mexico constitute the largest continuous rhyolitic province in the world. The rhyolites appear to represent part of a continental magmatic arc that was emplaced when an eastward-dipping subduction zone was located beneath western Mexico.
