... The youngest highly explosive basaltic eruptions from Masaya Caldera in central western Nicaragua produced five main pyroclastic deposits: the San Antonio Tephra, La Concepción Tephra, the Masaya Triple Layer, and the Masaya Tuff with the Ti cuan-te pe Lapilli. This tephra sequence...

... Fig. 6 . The shoreline 2 berm is composed of volcanic sand that was reworked by lacustrine shoreline processes. This indicates that the shoreline 2 berm formed after an influx of volcanic sediments in and near the lake. The youngest volcanic unit mapped in this area is known as the Masaya Tuff...

... ( Sterpenich and Libourel 2001 ; Moune et al. 2007 ). The unaltered composition measured at Masaya is similar to that of the mafic droplets from Payenia ( Fig. 7b ). Globules reported from ash flow tuffs in Kenya are both silicate and carbonate in composition ( Macdonald et al. 1993 ) and show some...

... experiments show that D Br is typically much larger than D Cl ( Bureau et al., 2000 ), and the ratio Br/Cl in a melt should steeply decrease during partial degassing, which can be observed in particular in the Cosiqüina 1835, Masaya Tuff, and Masaya Triple Layer melt inclusions ( Fig. 2C ). The intrasample...

... Layer and Masaya Tuff, which both stem from Masaya Caldera. Williams (1983a , 1983b ) studied these three products of highly explosive eruptions from Masaya Caldera in detail. His data on Fontana Tephra provided a useful starting point for our investigation. Williams attributed the sheet-like geometry...

... to be relatively recent based on its weak pedogenesis. The volcanic deposits form a scarp affected by toppling and are made up of a sequence of volcanic tuff attributed to the Masaya group, probably deposited during the Holocene (Fig.  2c , Ⓔ Fig. S3). The other trench showed a very recent alluvial fan containing...

... around the vent and can initially have supersonic velocities. The largest phreatomagmatic surge deposit known in Nicaragua, the <2000 yr old Masaya Tuff (Pérez and Freundt, this volume), has spread near-radially up to 40 km around Masaya caldera. Pyroclastic surge deposits commonly...

... fractionation process. Based on this assumption, it is possible to evaluate the amount of gas present in the various parcels of magma sampled by the melt inclusions. Such an approach has been applied successfully to the Bishop Tuff eruption ( Wallace et al. 1995 , 1999 ) and also to the 1991 Pinatubo eruption...

... described by Björnsson et al. (1977) as a dacitic welded air-fall tuff. Subsequent work by Calderone et al. (1990) identified a range of compositions from basalt to rhyolite, which they attributed to magma mixing during basaltic recharge of a rhyolitic chamber. Based on 40 Ar/ 39 Ar dating, Sæmundsson...
