Clarkia Tenella Is Tetraploid, Having N 34 (Hiorth, 1941; Raven and Lewis, 1959) and 2Fl32 (Moore and Lewis, I965b)
VARIATION AND EVOLUTION IN SOUTH AMERICAN CLARKIA D. M. MOORE and HARLAN LEWiS Botany Department, University of Leicester and Botany Department, University of California, Los Angeles Received5.V.65 1.INTRODUCTION THEgenus Clarkia (Onagracee), currently considered to contain 36 species, is restricted to the western parts of North and South America (fig. i). The 35 North American species are distributed from Baja California to British Columbia (300N.to 48° N.), most of them occurring in California. The South American populations, which have a smaller though still considerable latitudinal spread (290 30' S. to 42030'S.), comprise a single variable species, Clarkia tenella (Cay.) H. and M. Lewis (Lewis and Lewis, within which four sub.. species have been recognised (Moore and Lewis, i 965b). Clarkia tenella is tetraploid, having n 34 (Hiorth, 1941; Raven and Lewis, 1959) and 2fl32 (Moore and Lewis, i965b). It is placed in section Godetia, together with seven North American species, and shows its closest affinities with the only tetraploid among these, C. davyi (Jeps.) H. and M. Lewis. A study of artificial hybrids between C. tenella and C. davji, together with pakeo-ecological evidence, led Raven and Lewis (i) to hypothesise that the two species were derived from a common tetraploid ancestor which had traversed the tropics by long-distance dispersal during or since the Late-Tertiary and given rise to the populations now comprising C. tenella. Detailed study of the variation within Clarkia tenella was made possible by a field trip to Chile and Argentina during 1960-61 and by subsequent experimental work at Leicester and Los Angeles. -
Appendix A. Supplementary Material to the Manuscript
Appendix A. Supplementary material to the manuscript: The role of crustal and eruptive processes versus source variations in controlling the oxidation state of iron in Central Andean magmas 1. Continental crust beneath the CVZ Country Rock The basement beneath the sampled portion of the CVZ belongs to the Paleozoic Arequipa- Antofalla terrain – a high temperature metamorphic terrain with abundant granitoid intrusions that formed in response to Paleozoic subduction (Lucassen et al., 2000; Ramos et al., 1986). In Northern Chile and Northwestern Argentina this Paleozoic metamorphic-magmatic basement is largely homogeneous and felsic in composition, consistent with the thick, weak, and felsic properties of the crust beneath the CVZ (Beck et al., 1996; Fig. A.1). Neodymium model ages of exposed Paleozoic metamorphic-magmatic basement and sediments suggest a uniform Proterozoic protolith, itself derived from intrusions and sedimentary rock (Lucassen et al., 2001). AFC Model Parameters Pervasive assimilation of continental crust in the Central Andean ignimbrite magmas is well established (Hildreth and Moorbath, 1988; Klerkx et al., 1977; Fig. A.1) and has been verified by detailed analysis of radiogenic isotopes (e.g. 87Sr/86Sr and 143Nd/144Nd) on specific systems within the CVZ (Kay et al., 2011; Lindsay et al., 2001; Schmitt et al., 2001; Soler et al., 2007). Isotopic results indicate that the CVZ magmas are the result of mixing between a crustal endmember, mainly gneisses and plutonics that have a characteristic crustal signature of high 87Sr/86Sr and low 145Nd/144Nd, and the asthenospheric mantle (low 87Sr/86Sr and high 145Nd/144Nd; Fig. 2). In Figure 2, we model the amount of crustal assimilation required to produce the CVZ magmas that are targeted in this study. -

Volcán Lascar
Volcán Lascar Región: Antofagasta Provincia: El Loa Comuna: San Pedro de Atacama Coordenadas: 21°22’S – 67°44’O Poblados más cercanos: Talabre – Camar – Socaire Tipo: Estratovolcán Altura: 5.592 m s.n.m. Diámetro basal: 8.9 km Área basal: 62.2 km2 Volumen estimado: 28.5 km3 Última actividad: 2015 Última erupción mayor: 1993 Volcán Lascar. Vista desde el norte Ranking de riesgo (Fotografía: Gabriela Jara, SERNAGEOMIN) 14 específico: Generalidades El volcán Láscar corresponde a un estratovolcán compuesto, elongado en dirección este-oeste, activo desde hace unos 240 ka y emplazado en el margen oeste de la planicie altiplánica. Está conformado por lavas andesíticas, que alcanzan más de 10 km de longitud, y por potentes lavas dacíticas que se extienden hasta 5 km, las que fueron emitidas desde los flancos NO a SO. La lava más reciente se estima en 7 mil años de antigüedad. En los alrededores del volcán se reconocen depósitos de flujo y caída piroclástica, además de numerosos cráteres de impacto asociados a la eyección de bombas durante erupciones plinianas y subplinianas. El principal evento eruptivo durante su evolución se denomina Ignimbrita Soncor, generado hace unos 27 ka al oeste del volcán y con un volumen estimado cercano a los 10 km3. En la cima de este volcán se observan seis cráteres, algunos anidados, y el central de estos se encuentra activo. Registro eruptivo Este volcán ha presentado alrededor de 30 erupciones explosivas desde el siglo XIX, lo que lo convierte en el volcán más activo del norte de Chile. Estos eventos han consistido típicamente en erupciones vulcanianas de corta duración, con emisión de ceniza fina y proyecciones balísticas en un radio de 5 km, donde el último evento de este tipo ocurrió el 30 de octubre del 2015. -

Small steam-driven volcanic explosions are common at volcanoes worldwide but are rarely documented or monitored; therefore, these events still put residents and tourists at risk every year. Steam-driven explosions also occur frequently (once every 2-5 years on average) at Lascar volcano, Chile, where they are often spontaneous and lack any identifiable precursor activity. Here, for the first time at Lascar, we describe the processes culminating in such a sudden 15 volcanic explosion that occurred on October 30, 2015, which was thoroughly monitored by cameras, a seismic network, and gas (SO2 and CO2) and temperature sensors. Prior to the eruption, we retrospectively identified unrest manifesting as a gradual increase in the number of long-period (LP) seismic events in 2014, indicating an augmented level of activity at the volcano. Additionally, SO2 flux and thermal anomalies were detected before the eruption. -

Chile by Martin Nicholas and Ivan.Pdf
FLAG • The Chilean flag is also known in Spanish as La Estrella Solitaria (The Lone Star). • It was adopted on 18 October 1817. • The flag of Chile consists of two equal horizontal bands of white and red, with a blue square the same height as the white band in the canton, which bears a white five-pointed star in the centre. CAPITAL • The capital of Chile is called ‘Santiago’. • Santiago is the biggest city in Chile. • It sits in a valley surrounded by the snow- capped Andes and the Chilean Coast Range. • Plaza de Armas, the grand heart of the city’s old colonial core, is home to 2 neoclassical landmarks: the 1808 Palacio de la Real Audiencia, housing the National History Museum, and the 18th-century Metropolitan Cathedral. POPULATION • The population of Chile is 18,183,803. • The population rate growth for Chile was decreasing in 1990. • By 2050 the population is expected to reach approximately 20.2 million people. • About 85% of the country's population lives in urban areas, with 40% living in Greater Santiago. FOOD • Pastel de Choclo: corn casserole with meat stuffing. • Empanadas: pastry filled with meat, cheese or mussels. • Cazuela: homemade stew with beef, chicken, corn, rice and potatoes. • Asado: barbeque of beef, pork or chicken. FESTIVALS • Viña del Mar International Song Festival: This festival the largest and best known music festival in Latin America. • Lollalpalooza Chile: this festival is the Chile based version of the popular music festival Lollapalooza. • Ultra Chile: this is an outdoor electronic music festival that is a part of Ultra Music Festival’s worldwide expansion, which has now spread to 20 different countries.
