Petrographic analysis of Early Permian, nonmarine strata of the Abo Formation (and equivalent strata) reveal a wide range in plagioclase and K-feldspar percentages and highly variable feldspar alteration trends throughout northern, central, and southern New Mexico. Sandstone modal composition trends show a significant decrease in detrital K-feldspar and increase in plagioclase as you compare percentages from northern (P=53%; K=47%), central (P=85%; K=15%), and southern New Mexico (P=97%; K=3%). In addition, elevated occurrences of diagenetic albite are in higher abundance in these strata in central and southern New Mexico compared to northern New Mexico.

The Valles Caldera is a large volcanic feature in Northern New Mexico that has had geothermal activity since its formation at 1.25 Ma. Volcanic H2S is currently emitted along the western margin of the Caldera through fumaroles and in natural and artificial hot springs. We explored the microbial communities and processes associated with volcanically-influenced surface waters in the Sulfur Springs and Alamo Canyon area of Valles Caldera National Preserve, and in hot springs along the Jemez River to the south. Surface waters impacted by fumarolic gases in the Alamo Canyon and Sulfur Springs areas had pH values between 1.1 to 3.5, with dissolved sulfide concentrations from 10 μM up to 1 mM in areas with the most intense fumarolic activity. In contrast, hot springs at Soda Dam and an artificial spring in the town of Jemez Springs had temperatures between 37-70ºC, circumneutral pH values, and sulfide concentrations between 5-25 μM. Small subunit rRNA gene libraries from Alamo Bog had diverse eukaryotic algae and a wide variety of bacteria related to known chemoautotrophic sulfur oxidizers, including Sulfurimonas spp., Sulfuriferula spp., Halothiobacillus spp., and Thiomonas spp. The more acidic sites in Sulfur Springs are dominated by the bacterial and archaeal genera Acidithiobacillus, Sulfobacillus, Acidiphilium, and Acidiplasma. Green and white streamers from the Soda Dam springs were dominated by Sulfurovum, Thiofaba, Thiothrix, and several cyanobacterial taxa. The most acidic samples were the least diverse, but there was not a strong correlation between microbial diversity and pH. Diversity was also negatively correlated with dissolved sulfide concentration. Future work will continue to explore how geochemical

As part of a continuing investigation of trace fossils from the lower-most, Albian Sarten Member of the Mojado Formation, we report the first description of Curvolithus simplex at Cerro de Cristo Rey, Sunland Park, New Mexico. C.simplex is a horizontal, three-lobed trace interpreted as a repichnia. Other traces in this ichnoassemblage that are commonly associated with the Cruziana ichnofacies include Thalassinoides, Arthrophycus, Planolities, scratch marks (and others not yet reported). Our Curvolithus specimensare preserved exclusively in convex epirelief on iron-stained, massive sandstones, interbedded with thin grey shales. At this location the lower contact of the Sarten Member is easily distinguishable from the Mesilla Valley Formation below. Although the base of the Mojado Formation was originally defined arbitrarily by the thickness of sandstone interbeds, or a change in sandstone lithology, we see a distinct change in ichnoassemblages between these two Formations, which may be used to define the contact in the future.
作为对最底层Mojado组Albian Sarten成员的痕迹化石的持续调查的一部分，我们报告了在新墨西哥州桑兰公园的Cerro de Cristo Rey的首次描述。单纯弧菌是一种水平的，三叶状的痕迹，被解释为一种螺旋体。该组合中通常与克鲁齐亚纳鱼相相关的其他痕迹包括Thalassinoides、Arthrophycus、Planolities、划痕(以及其他尚未报道的)。我们的弯曲岩标本仅保存在铁染的大块砂岩的凸面上，这些砂岩与薄的灰色页岩互层。在这个位置，萨滕成员的较低接触很容易与下面的梅西拉山谷地层区分开来。虽然Mojado组的基底最初是由砂岩互层厚度或砂岩岩性变化随意确定的，但我们发现这两个组之间的岩石组合有明显的变化，这可能用于确定未来的接触。
