Gravity Variations in Central Chile

1993
Results corresponding to variations of the vertical component of gravity, associated with the March 3, 1985 earthquake are here reported. These processes frequently involve surface modifications near the rupture zone, which can be detected by means of precise gravimetric measurements. In Central Chile, the area affected by the March 1985 earthquake was

Forest Dynamics in South-Central Chile

Journal of Biogeography, 1981
Forest structure and dynamics are analysed and compared for No thofagus-dominated forests in the Andes and for forests lacking Nothofagus in the Coastal Cordillera of the Province of Valdivia (c. 400S latitude), Chile. At mid-elevation (c. 600-950 m) in the Andes, even-aged Nothofagus stands develop on sites devastated by mass movements and volcanic ...

Zeolitization of tuffs at Quinamávida, central southern Chile

Clays and Clay Minerals, 2007
AbstractTuffs of the Tertiary Colbún Formation near Quinamávidain central southern Chile have been mapped and their mineralogy analyzed. The pyroclastic rocks present a maximum outcropping thickness of 120 m and are dominated by vitreous lapilli and minor lithic tuffs, the products of active volcanism nearby. About 10% of the tuffs consist of lenses of

Managing wild crops of Gracilaria in central Chile

Hydrobiologia, 1984
The species of the genus Gracilaria (Rhodophyta) provide nearly 48% of the raw algal material exported annually from Chile (Santelices & Lopehandia, 1981). About 50% of this material is gathered as thalli cast ashore from three beds of Gracilaria lemaneiformis (Bory) Weber-van Bosse in Central Chile (30 ° S, 71 ° W).
