The purpose of this study was to continue the assessment of low-temperature geothermal resources in Utah started . by the Utah Geological and Mineral Survey. The area of interest with in this report is north-central Box Elder County, Utah. Exploration techniques used included chemical analyses of water from wells and springs, temperature surveys, and temperature-depth measurements in unused wells within the study area. The highest water temperatures (31, 30, and 290c) recorded in this research were located in three separate geographic regions, suggesting that no single warm water occurrence dominates the study area. Total dissolved solid (T:DS) concentrations ranged from 294 to 11,590 mg/1. Areas of warm water occurrences generally had TDS values of greater than 1,100 mg/1. Three water types were distinguished using trilinear plots of common ion analyses of collected water samples. The warmest wells were of Type III water character, which has high (>75%) sodium and chloride concentrations. Reservoir temperatures were estimated using the water chemistry. Both the silica and the Na-K-Ca geothermometers were used to calculate reservoir temperatures, averaging between 500c and 1 ooo c. If mixing effects are taken into account, reservoir temperatures might be as high as 198°C. Temperature-depth measurements were logged in 16 unused wells. Thermal gradients calculated from the profiles ranged from isothermal to 267oC/km. The background gradient for the study area appears to be slightly above the average Basin and Range gradient of 35oC/km. The highest gradients were calculated for the area approximately 8 kilometers west of Snowville, Utah, which is also an area of warm water. Several areas of possible low-temperature geothermal interest have been identified in the study area by considering water temperatures, calculated reservoir temperatures, and temperature-depth data. However, additional work is needed to more accurately define the possible geothermal resource in these areas.

The Lower Middle Cambrian Langson Formation was studied in the xi Bear River Range of north-central Utah and southeasternmost Idaho and the Wellsville Mountains of north-central Utah. The depositional textures and sedimentary structures preserved within the rocks were compared with characteristics of similar modern sediments and ancient rock to determine environments of deposition, paleogeography, diagenetic alteration and pattern of dolomitization. The rocks of the Langston Formation were divided into eleven different rock types. These eleven rock types were formed within four recognizable lithofacies: 1) upper peritidal; 2) inner carbonate shelf; 3) inner clastic shelf; and 4) outer clastic shelf. The general depositional environment is inferred to have been a shall ow subtidal to subaerial carbonate shoal complex. Clastic sediments from the east and north or northwest periodically prograded over the carbonate complex during times of relatively slow subsidence. The deposition of the Langston Formation mudrocks and carbonates occurred during the first Cambrian grand cycle. Eogenetic diagenetic features include birdseye structures, relict evaporite structures, fibrous rim cement, compaction, and the begining of dolomitization. Mesogenetic diagenesis is characterized by dolomitization and pressure solution. Telogenetic diagenesis is limited to fracturing and calcite infilling. Dolomitization is believed to have resulted mainly from downward reflux of hypersaline brines, as indicated by relict evaporite structures, zoned dolomite rhombs, and a general association of dolomite with upper peritidal facies. The hypersaline brines formed in the upper peritidal environment, and percolated downward through underlying porous sediments. The greater density of the hypersaline brines displaced less-dense interstitial fluids. These brines were periodically diluted by normal marine water or fresh water.

The study of the characteristics of the Late Archaic Period societies on the North-Central Coast probably is one of the most important areas of archaeological research in the last ten years. This paper evaluates the quality of the current archaeological data. A review of the reported information reveals a need to establish a more precise characterization of the architectural designs and construction processes that shaped the conspicuous public buildings of this period. Also revealed is the need to refine the occupational sequences of the Late Archaic architectural complexes of the North-Central Coast, which is necessary for a better understanding of the processual characteristics of their cultural development. As a beginning point, data recovered from excavations in the site of Cerro Lampay, a small architectural compound of the Fortaleza Valley, are studied. Information from Cerro Lampay is compared with published data from other sites, including Áspero, Chupacigarro, Caral, Caballete, and Porvenir. / La naturaleza de las sociedades del Periodo Arcaico Tardío en la costa norcentral ha sido, probablemente, uno de los temas más recurrentes en los últimos 10 años. Para contribuir a esta discusión, se hace necesaria una evaluación de la calidad de la base empírica existente hasta el día de hoy en el registro arqueológico. Una revisión de los datos documentados revela la necesidad de establecer con mayor precisión las características del diseño arquitectónico y el proceso constructivo de los conspicuos edificios públicos de este periodo. Además, muestra que es necesario el afinamiento de las secuencias ocupacionales de los distintos complejos arquitectónicos del Periodo Arcaico Tardío en la costa norcentral como requisito para entender las características procesales del desarrollo cultural que allí se dio. Esta revisión parte de los datos recuperados en las excavaciones en Cerro Lampay, un pequeño conjunto arquitectónico del valle de Fortaleza. Esta información es comparada con la de otros sitios, como Áspero, Chupacigarro, Caral, Caballete y Porvenir.

The Cerro Blanco site, located in the lower Nepeña Valley, is a ceremonial center of the Formative Period, which has been considered, without adequate substantiating data, to have been influenced by the Chavín culture. In this brief paper, a local chronology, complemented with data from the nearby site of Huaca Partida, will be presented in an attempt to establish Cerro Blanco within an interregional chronological frame. On the basis of the new archaeological evidence, this broad synchronic comparison suggests an episode of intensive trans-regional interaction. In this context, Cerro Blanco emerges as an essential site for understanding social dynamics during the Andean Formative Period. / El sitio de Cerro Blanco, ubicado en el valle bajo de Nepeña, es un centro ceremonial del Periodo Formativo que, desde su descubrimiento a inicios del siglo XX, ha sido considerado receptor de la influencia chavín, aunque sin ofrecerse las explicaciones apropiadas al respecto. En este breve ensayo se presenta, en primer lugar, una secuencia local complementada con los datos del sitio vecino de Huaca Partida y, luego, se trata de ubicar dicha secuencia dentro de un marco cronológico interregional. Esta comparación sincrónica sobre la base de las nuevas evidencias pone en relieve un episodio de intensiva interacción transregional ocurrido durante el Periodo Formativo, en cuyo marco Cerro Blanco de Nepeña surge como uno de los sitios clave para entender la dinámica de esta etapa prehispánica.
