Trigo Rodríguez, Josep María; Llorca, Jordi; Weyrauch, Mona; Bischoff, Addi; Moyano Cambero, Carles E.; Keil, Klaus; Laubenstein, Matthias; Pack, Andreas; Madiedo Gil, José María; Alonso Azcárate, Jacinto; Riebe, My; Wieler, Rainer; Ott, Uli; Tapia, Mar; Mestres, Narcís (Meteoritical Society, 2014)
We report and describe an L6 ordinary chondrite fall that occurred in Ardón, León province, Spain (longitude 5.5605°W, latitude 42.4364°N) on July 9th, 1931. The 5.5 g single stone was kept hidden for 83 yr by Rosa Gonzólez ... -
Estudio de los procesos de septaritización, cementación y reemplazamiento de las concreciones carbonatadas asociadas al yacimiento de piritas de Navajún. Cuenca de Cameros (La Rioja)
(Sociedad Geológica de España, 1996)Associated to the Navajun pyrite deposits (Cameros basin. North Spain), it appears a lutite horizont with decimetric carbonate concretions normally septarized. This septarization occured during early diagenesis, and it ... -
Evolución desde la diagénesis temprana al metamorfismo de los nodulos edáficos del grupo Urbión. Cretácico inferior. Cuenca de Cameros, La Rioja
(Sociedad Geológica de España, 1996)Pedogenetic carbonate nodules are a common feature in most of the depositional sequences of the Late Jurassic-Early Cretaceous Cameros Basin. This study deals with postsedimentary history (from early diagenesis to metamorphism) ... -
La evolución temporal de los minerales de la arcilla en el Pérmico superior y Triásico de Cuenca y Teruel (Cordillera Ibérica SE)
(Sociedad Geológica de España, 1994)Clay mineralogy of the continetal and shallow marine sediments of Permian and Triassic age of the SE Iberian Ranges is a neglected subject. The present study shows the temporal variations of clay mineral assemblages and ... -
The impact of neos and their fragments recorded from the ground : ongoing research lines of the spanish fireball network
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Llorca, Jordi; Williams, I. P.; Castro Tirado, Alberto J.; Ortiz Moreno, José Luis; Alonso Azcárate, Jacinto; Zamorano, J.; Lanchares, Víctor; Docobo, José A.; Fabregat Llueca, Juan (2009)
A continuous monitoring of the night sky all over Spain will be completed in 2009. This involves the recording over a very large surface area of 500,000 km2, but new CCD and video cameras operated by the Spanish Meteor ... -
Ir reflectante spectra of Antartic carbonaceous chondrites to better characterize the surfaces of asteroids targetted by sample return missions
Trigo Rodríguez, Josep María; Llorca, Jordi; Madiedo Gil, José María; Alonso Azcárate, Jacinto; Rivkin, A. S.; Fornasier, S.; Belskaya, I.; Binzel, R.; Moyano Cambero, Carles E.; Dergham, J.; Cortés, J. (2012)
Undifferentiated carbonaceous asteroids have experienced complex collisional histories, and a significant number are fragments of larger bodies. Meteorites arrived from these asteroids exhibit an amazing reflectance ... -
Large meteoroids from the 2P/Encke complex : orbital data of 2010 taurids recorded in the framework of the Spanish fireball network

F. L. Whipple first modeled the forma-tion of meteoroid streams from the continuous subli-mation of the ice-rich regions in cometary nuclei [1,2,3]. Particles lifted off from ice-rich regions by the sublimated gas drag ... -

The development of a network of meteor observing stations allows for a continuous monitoring of meteor phenomena. One of the main goals of the SPanish Meteor Network (SPMN) is the analysis of the physico-chemical ... -
Orbit, emission spectrum, and photometric analysis of two flickering sporadic fireballs
Madiedo Gil, José María; Trigo Rodríguez, Josep María; Konovalova, N.; Ortiz Moreno, José Luis; Castro Tirado, Alberto J.; Alonso Azcárate, Jacinto; Lacruz, J.; Cabrera Caño, Jesús (EDP Sciences, 2013)
We present the observations of two fireballs that exhibit fast and quasi-periodic brightness variations along their atmospheric path. This phenomenon, which is known as “flickering”, is associated to the entry of spinning ... -
Origen de las piritas de la cuenca de Cameros, (La Rioja)
(Sociedad Geológica de España, 1995)The pyrite mineralizations of the Cameros basin has been traditionally interpreted as diagenetic. On the basis of trace element content, S isotopes study, pyrite inclusions and geologic observations, the pyrite crystals ... -
