Annual Fall Field Conference
2016: Geology of the Belen Area,
September 14th - 17th

Every fall since 1950, the Society has held a field conference to some part of New Mexico and, in some cases, to border states. From the beginning, the conference has been accompanied by a guidebook with detailed road logs as well as peer-reviewed papers relevant to the region. These guidebooks remain as invaluable references to the geology of the conference study area and most are available for purchase.

Widespread enthusiasm for the Fall Field Conferences has led to receipt of many proposals for future conferences. Therefore, the schedule of upcoming field conferences is now outlined for the next several years. The field conference venues and names of organizers are listed below. All members are encouraged to volunteer assistance to the organizers or to contribute to the guidebooks. If you live near or are involved with the geology in the vicinity of the future conference sites, please consider contacting one of the organizers.

2016 Conference: Belen Area
route

The 2016 NMGS Fall Field Conference will focus on the area in and around the Rio Grande rift near Belen, New Mexico. The area has a rich 1.7-billion-year geologic history recorded by Precambrian basement exposures, Paleozoic and Mesozoic stratigraphy, Laramide structures, Rio Grande rift history, industrial minerals deposits, Tertiary volcanic activity, Quaternary geomorphology, and hydrologic/paleohydrologic features.

Pre-meeting Trips

Participants can choose to go on one of two pre-meeting trips (limited to 20 participants each) to geologically-significant areas of the Sevilleta National Wildlife Refuge – 1) travel west across pre-rift and rift-related volcanic and sedimentary rocks and structures to the travertine-capped West Mesa, or 2) travel east to examine the diverse Phanerozoic geology and geomorphology between the Rio Grande and Los Pinos Mountains.

Field Conference Overview

Day 1 leads participants southeast of Belen to Black Butte (Turututu) to discuss Rio Grande rift history, Tertiary volcanism, and geomorphic development in the area. Participants will then drive the most westerly railroad structures of Abo Pass to reach Sand Canyon in the southern Manzano Mountains to view the Montosa monocline and other evidence of the Laramide orogeny. The final stop of the day will involve a one-mile-long hike in Estadio Canyon to consider the complex Precambrian structural components of the canyon and the metamorphic and deformational aureole of the 1.45-Ga Priest pluton.

Day 2 focuses on the geology west of Belen with stops in Carrizo Arroyo to examine Paleozoic and Cenozoic stratigraphy and Laramide structures exposed in the rift flank; the day will end with a re-cap at an overlook of the Rio San Jose Gorge to talk about river incision, hydrology, and Tertiary and Quaternary volcanism.

Day 3 visits the travertine quarries west of Belen to investigate paleohydrology and paleoclimate, depositional environments, and the features found in travertine deposits. The conference will end with a hike to active travertine-depositing springs.

Conference organizers are:
Shannon Williams, Bonnie Frey, and Karl Karlstrom

The conference will be based out of the Holiday Inn in Belen. Dave Love, Karl Karlstrom, Spencer Lucas, Jason Ricketts, Richard Chamberlin, Laura Crossey, Dan Koning, and Alexandra Priewisch will be among the presenters.

Guidebook

The guidebook for the conference covers many aspects of the geology and history of the Belen area and includes 5 detailed road logs, 19 minipapers, and 28 research papers.

A full version of the 2016 Guidebook is included with registration. A spiral bound Guidebook containing roadlogs and minipapers only will be available for separate purchase at the conference.

We hope to make papers from the new guidebook available online for current members prior to the conference.
