RT Journal Article T1 Influencia de las burbujas en la viscosidad de magmas haplograníticos vesiculados T1 Bubble effects on the viscosity of vesiculated haplogranitic magmas A1 López, S. A1 Fernández Rodríguez, Carlos A1 Donaire Romero, Teodosio A1 Castro Dorado, Antonio AB The changes in the viscosity of bubble-bearing haplogranitic magmas with crystallinity are a prime function of the applied deformation rate. Under high deformation rates melt and magma viscosities are found to strongly increase with crystallinity. Low deformation rates promote, instead, a decrease in melt viscosity and a rather small increase in magma viscosity with crystallinity. These changes could explain some observed geological features in plutons PB Sociedad Geológica de España YR 2002 FD 2002 LK http://hdl.handle.net/10272/9110 UL http://hdl.handle.net/10272/9110 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
