NMGS Fall Field Conference Guidebook, 1996
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. 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, and other selected content are available only in print for recent guidebooks.

Water samples from springs and wells from the Cuitzeo Basin (Michoacan state, Mexico) have been studied to investigate the main geochemical features of deep waters assessing moderate temperature geothermal resources in Mexico for direct uses. Radon measurements were also performed. Waters were classified as bicarbonate, chloride and sulfate according to their origin. Partially equilibrated and immature waters were found with reservoir temperatures ranging between 129 and 216oC. Silica temperature results indicate that the reservoir temperatures range between 100 and 200°C. Those temperatures are useful not only for direct uses but also for the generation of electricity. The average groundwater radon concentration values were relatively low indicating an efficient fluid circulation pattern.

A promissory low-to-medium temperature geothermal system located in Sonora (Mexico) has been studied. In the present work, a detailed geochemical survey was carried out to understand the hydrogeochemical signatures of hot spring waters. A field work campaign was conducted for collecting water samples from twelve hot springs placed in four major zones (NW, NE, C, and S). The collected samples were analysed by chemical and isotopic methods for determining their chemical (major and trace elements) and isotopic (18O/16O and D/H) compositions. Using geochemometric analyses of the fluid composition and fractionation, depletion and enrichment processes exhibited by major and trace elements were analysed. Hydrogeochemical classification was used to indicate the presence of sodium-sulphate (Na-SO4) waters in the North (NW and NE) and South hydrothermal zones; whereas calcium-magnesium-bicarbonate (Ca-Mg-HCO3) waters were identified for the Central zone. Some hot spring waters located in the ...
