Název v původním jazyce

The volcano-tectonic evolution of the Miocene Santa Lucía Volcano, Boaco district, Nicaragua

Popis výsledku v původním jazyce

On the basis of field mapping, petrological and geochemical data, a new model for the evolution of the Santa Lucía Volcano is presented. The first stage consisted of a series of strong Sub-Plinian eruptions, which produced thick ignimbrite units. These events destroyed the pre-existing volcanic edifice. The second stage was dominated by large explosive eruptions producing mainly non-welded dacitic?andesitic ignimbrites. The next resulted in the formation of andesitic lava flows and minor tephra fall-outdeposits, covered by voluminous basaltic lavas. Lahars probably triggered by volcanic and/or seismic events represent the final stage of volcanic activity. From the Miocene onwards, volcanic rocks became deeply weathered and locally eroded. Strongly weathered rocks are susceptible to landslides, and surficial modification by post-volcanic slope movements is observed on the slopes of the Santa Lucía Volcano.
