Collections of both species included speci- mens taken north ofPatagonia. A. elsia was describedby CALVERT (1952) from specimens from Pacasmayo, Peru. He also included material from Lima, Pachitea, vicinity of Chosica, vicinity of Villa and Repartition (Peru), Tacna, Azapa, Mini-Mini and Curico (Chile), and “Patagonia”. As the description and later redescription of A. elsia (CALVERT, 1952, 1956) do not easily allow its separation from the other species of the subgenus Neureclipa Navas, 1911 (sensu CALVERT, 1952), a redescription is included, together with the description of a new species of the subgenus Hesperaeschna Cockerell, 1913. For the wing venation the terminology given by RIEK & KUKALOVA-PECK (1984), and for the description of the abdominal colour pattern that proposed by WALKER (1912). Material examined is deposited at the following collections: MLP - DepartamentoCientlfico Entomologla, Museo de La Plata, Buenos Aires, Argentina; FML — Fundacion Miguel Lillo, Tucuman, Argentina; - MNFIN Museo Nacional de Historia Natural de Santiago, Chile; IEUM - Institute de Entomologia, Universidad Metropolitana de Ciencias de la Educacion, Santiago, Chile; — UMMZ University of Michigan,Museum of Zoology, MI, U.S.A.

Chile shared of copper in terms of volume and value, producing 30.8% of the the U.S. interest in negotiating a comprehensive trade world's mined copper.

  • Unidades Sedimentarias Cenozoicas De La Cuenca Del Rio Loa En La Pampa Del Tamarugal, Region De Antofagasta, Chile

Geol. y Minería, Casilla 10465, Santigo, Chile. ROLAND. P. PASKOFF Département de Géographie, Université de Tunis, 94, Bd. du 9 avril1938, Túnez. RESUMEN El relleno sedimentario de la cuenca del río Loa, en la Pampa del Tamarugal, es de gran complejidad. En él es posible distinguir al menos seis unidades diferentes. Su génesis se explicaría por la intervención e interacción de cambios climáticos en un ambiente árido, y de movimientos tectónicos durante el Cenozoico. ABSTRACT The sedimentary filling of the Pampa del Tamarugal in the Río Loa basin is compleXo At lcast six different units can be distinguished. Interferences between climatic changes in an arid environment and tectonic move­ ments account for their genesis. INTRODUCCION Durante mucho tiempo se ha pensado que el voluminoso relleno de depósitos aluviales y evapo­ ríticos de la depresión seguida por el río Loa, entre Calama y Quillagua (Fig. 1), correspondería a una sola formación, la Formación El Loa (Brüggen, 1950; Fuenzalida, 1957). Esta opinión prevalece todavía en estudios geológicos recientes (Boben­ rieth, 1980; Boric, 1980; Maksaev y Marinovic 1980), pese a que, en 1975, Rieu llamó la atención sobre la complejidad de los depósitos que rellenan la cuenca. Efectivamente, es posible distinguir va­ rias unidades estratigráficas, claramente separadas por discordancias de erosión (Fig. 2). Recientemente, Naranjo y Paskoff (1981) han caracterizado la estratigrafía del Cenozoico del sec­ tor comprendido entre Chiuchiu y Calama (22°20'- 22°27'S).

El río Loa nace en la falda norte del Vn. Mi­ ño~ en los Ojos del Hiño, casi en los límites entre la la y IIa Regio­ nes de Chile, en 21Q15' L.S. y 70Q L.O~ Su longitud total se acerca a 440 km. A pesar de su extensa hoya, los recursos h!dricos provienen de la cuenca alta que comprende alrededor del 20% de la su~ perficie total. Con curso aproximadamente norte-sur~ el Loa reco­ rre casi 150 km en un profundo cañón de altura variable, desde su nací miento hasta el oasis de Chiu ~hiu, pueblo que se levanta en su margen izquierda. En este trayecto recibe sus dos tributarios más importantes que le caen del este: el río San Pedro o Inacaliri y el río Salado. En Chiu Chiu dobla su curso sensiblemente hacia el oeste para alcanzar en un recorrido de 115 km el punto denominado Chacance. En él se le reúne por la derecha el río San Salvador. En Chacance,el Loa toma franca di= recci6n sur-norte hasta fertilizar el oasis de Quillagua, despu~s de una trayectoria de 80 km. A partir de Quillagua el Loa describe un gran arco y luego desemboca en el Pacífico~ en Caleta Huel~n, despu~8 de trasponer el macizo costero en un tajo profundo~ de más de 500 m de al­ tura.

Investments in forest plantations have grown in the last 40 years thanks to implementation of the Decree Law 701. Planted forests currently account for 17.4% of the total national forest cover. The objective of the study is to analyse non-industrial forest owners’ perceptions of positive and negative externalities of forest plantations in four less developed municipalities of the Maule Region. We implemented a literature review, the estimation of an Expert’s Response Indicator (ERI), and the implementation of an Analytic Hierarchy Process (AHP) methodology for the analysis.

  • Preliminary Survey of Some Soils from Chilean Altiplano Near Iquique
    J. Soil Sci. Plant Nutr. 11 (2): 63 - 72 (2011) PRELIMINARY SURVEY OF SOME SOILS FROM CHILEAN ALTIPLANO NEAR IQUIQUE P. Norambuena V.1*, W. Luzio L.1, O. Zepeda2, J. Stern1, and F. Reinoso1 1Facultad de Ciencias Agronómicas, Universidad de Chile, Casilla 1004, Avenida Cristóbal Colón 5805, Las Condes, Santiago, Chile. 2Environmental Engineer, Compañía Minera Doña Inés de Collahuasi, Andrés Bello 2687, Piso 11, Las Condes, Santiago, Chile. *Corresponding autor: edafoló[email protected] ABSTRACT In the Altiplano of the Iquique Province, Chile, a study was carried out for the purpose of advancing in the knowledge of the soils in the zone, to determine the soil moisture and soil temperature regimes, and to establish its taxonomic classification. In one area, at the base of the slopes of the Irruputuncu volcano, where the occurrence of lahars and the presence of moraine deposits is described, 5 soil profiles were examined morphologically and some of their chemical and physical properties were determined. Moreover, the degree of pedogenic evolution of the volcanic parent materials was assessed. The depth of the solum did not exceed 0.40 m, and the low organic carbon content, combined with the dominance of the sand fraction, determined a low water holding capacity, which hampers the development of vegetation. It was determined that the soil temperature regime is frigid and its moisture regime is ustic. None of the soils showed andic soil properties. Hence, given the limited pedogenic development it was proposed to classify them as Ustorthents (Entisols, USDA, 2010). Key words: High altitude soils, Ustic moisture regime, Andic properties, Entisols.

Before the year 2008, the genus Akymnopellis, was known to have a geographic distribution area from Atacama through Valdivia. A broader distribution of the genus was reported later. This study reports, the first insular record, new continental records, and a broader geographic area of distribution for the genus in the country. An identification key is provided for species of the genus Akymnopellis. Key words: Akymnopellis; new records; area of distribution; Chile.
