Oligo-Miocene extensional tectonics and fluid flow across the Northern Snake Range detachment system, Nevada

The Northern Snake Range (Nevada) represents a spectacular example of a metamorphic core complex and exposes a complete section from the mylonitic footwall into the hanging wall of a fossil detachment system. Paired geochronological and stable isotopic data of mylonitic quartzite within the detachment footwall reveal that ductile deformation and infiltration of meteoric fluids occurred between 27 and 23 Ma. Ar-40/Ar-39 ages display complex recrystallization-cooling relationships but decrease systematically from 26.9 +/- 0.2 Ma at the top to 21.3 +/- 0.2 Ma at the bottom of footwall mylonite. Hydrogen isotope (delta D) values in white mica are very low (-150 to -145 %) within the top 80-90 m of detachment footwall, in contrast to values obtained from the deeper part of the section where values range from -77 to -64 %, suggesting that time-integrated interaction between rock and meteoric fluid was restricted to the uppermost part of the mylonitic footwall. Pervasive mica-water hydrogen isotope exchange is difficult to reconcile with models of Ar-40 loss during mylonitization solely by volume diffusion. Rather, we interpret the Ar-40/Ar-39 ages of white mica with low-delta D values to date syn-mylonitic hydrogen and argon isotope exchange, and we conclude that the hydrothermal system of the Northern Snake Range was active during late Oligocene (27-23 Ma) and has been exhumed by the combined effects of ductile strain, extensional detachment faulting, and erosion.

Deficiencia nutricional de yodo en gestantes pertenecientes al distrito sanitario Sierra de Huelva-Andévalo, sur de España

Background. Iodine is an essential trace element implicated in synthesis of thyroid hormones. Iodine requirements vary throughout life. Yhis iodine requirement is increased during pregnancy and breastfeeding. In a previous study carried out by our group in 2008, we detected an iodine-deficient area in the province of Huelva, specially in dictrict Sierra de Huelva-Andévalo by means of neonatal TSH determinations. Objective. To reinforce the iodine supplementation campaign and its impact on their newborns in order to assess nutrition iodine status in 'pregnant women using questionnaire and ioduria determination. Material and methods. This study has been jointly carried out by Congenital Hypothiroidism Unit of the Clinical Biochemistry Department of the Virgen Macarena University Hosplital (Seville) and the Gynecology and Clinical Analysis Unit of the Río Tinto Hospital (Huelva) during two years. We studied 313 pregnant women. All of them filled out a personal questionnaire to know the iodine nutritional status in their area. Ioduria was determined by high-resolution liquid chromatography. Data from pregnant and results of the studied variables were analyzed with SPSS v.13.0. Conclusions. Pregnant women from the sanitary district Sierra de Huelva-Andévalo present a median for ioduria which corresponds to an insufficient iodine intake according to the WHO classification. The questionnaire suggest that this iodine deficiency is consequence of an insufficient iodine intake and a low adherence to the treatment.

Plan de Gestión de la red de senderos ecoturísticos de la Sierra de San Javier, Tucumán- Argentina

El “Parque Sierra de San Javier” és un espai natural al costat d’ un gran nucli urbà, San Miguel de Tucumán (Argentina). A la Sierra es troba la comuna de San Javier, on s’ ha creat el CIC (Centre Integrador Comunitari). És a partir del CIC que s’ elabora un pla integral que inclou el projecte d’ ecoturisme. Aquest projecte es basa en una gestió de la xarxa de camins existents a la Sierra. Es fa un inventari de cadascun dels camins de la xarxa i s’ analitza cadascun d’ ells amb uns índexs de potencial paisatgístic i interpretatiu i es valora també la seva conservació. A partir d’ aquests valors es planteja un pla d’ actuació de recuperació i manteniment, i un pla d’ actuació turística en el que es millora l’ estat del camí; s’ intal•len panells informatius i senyalització. El projecte conté les fitxes d’ informació de cadascun dels itineraris amb un mapa i amb d’ altres informacions d’ interès pels usuaris dels senders
