Storage conditions and eruptive dynamics of central versus flank eruptions in volcanic islands: the case of Tenerife (Canary Islands, Spain)
We report the results of phase equilibrium experiments on a phonolite produced during one of the most voluminous flank eruptions (ca. 1 km 3) of the Teide-Pico Viejo complex (Tenerife Island). Combined with previous experimental and volcanological data we address the factors that control the structure of the phonolitic plumbing system of Teide-Pico Viejo stratovolcanoes. The Roques Blancos phon...
متن کاملResults of tidal gravity observations in Tenerife, Canary Islands
c Tidal gravity observations have been carried out in Tenerife (Canary Islands) at the. base of the Teide volcano, more than two thousand meters above the sea level. The measurements have been done using a Lacoste&Romberg-G gravimeter (number 665), with electronic feedback during a period of six months. The results show, after a suitable correction of the ocean loading and attraction' effects, ...
متن کاملZeolites in Pyroclastic Deposits in Southeastern Tenerife (canary Islands)
-The chemical and the mineralogical composition of a group of pumiceous tufts associated with recent salic volcanic episodes from Tenerife (Canary Islands) have been studied. The investigation focused on the two main types of pyroclastic deposits of the zone: ash-flows and ash-falls. The samples can be classified chemically as trachytic and phonolitic rocks with an intermediate silica content a...
متن کاملBreeding biology of Grey Wagtail Motacilla cinerea canariensis on Tenerife, Canary Islands
The paper reports on the breeding biology of the endemic subspecies of the Grey Wagtail in a human transformed area (banana plantations) on Tenerife (Canary Islands). Clutch size (3.96 ± 0.6) was lower than in continental zones, probably because of the climatic stability of the islands. Furthermore, the distance from the nest to the nearest water source and the length of the breeding season (la...
متن کاملLimitations of biodiversity databases: case study on seed-plant diversity in Tenerife, Canary Islands.
Databases on the distribution of species can be used to describe the geographic patterns of biodiversity. Nevertheless, they have limitations. We studied three of these limitations: (1) inadequacy of raw data to describe richness patterns due to sampling bias, (2) lack of survey effort assessment (and lack of exhaustiveness in compiling data about survey effort), and (3) lack of coverage of the...
