2015/9/10
In the discussion of lava dome formation, viscosity of magma plays an important role. Measurements of viscosity
of magmas in field and laboratory are briefly summarized. The types of lava dome emplac...
VISCOSITY STUDIES ON DILUTE CLAY MINERAL SUSPENSIONS
CLAY MINERAL SUSPENSIONS VISCOSITY STUDIES
2011/11/15
A technique has been developed for obtaining reproducible viscometric data on dilute clay suspensions using the recently developed capillary viscometer of Maron, Krieger and Sisko. Aging and type of m...
Determination of the influence of pressure and dissolved water on the viscosity of highly viscous melts: Application of a new parallel-plate viscometer
Determination pressure dissolved water viscosity highly viscous melts:Application new parallel-plate viscometer
2012/4/1
A parallel-plate viscometer has been designed for use in an internally heated pressure vesse
(IHPV) at pressures up to 350 MPa and at temperatures up to 900 ?C. The viscosity of a melt is
determined...

Viscosity data for hydrous peraluminous granitic melts: Comparison with a metaluminous model
Viscosity data hydrous peraluminous granitic melts Comparison
2012/3/31
We performed 27 viscosity determinations on dry and water-bearing peraluminous hap-logranitic melts. The dry melt compositions cover the range of normative corundum to be expected in peraluminous gran...

The viscosity T/of dry and hydrous haplogranitic melts(anhydrous normative compo-sition: QZ28Ab340r38)has been determined between 3and 10kbar and 800 and 1400 DC using the falling-sphere method. The H...
The complex viscosity of a material is a two-component quantity, comprising real and imaginary parts. The real part of the complex viscosity is often very useful because in many materials it approache...
