Abstract
The methods of rotation viscometry have been applied in the field to a tholeiitic lava at 1130 degrees to 1135 degrees C containing about 25 percent crystals and 2 to 5 percent gas bubbles, using a stainless steel spindle inserted through the lava crust. The results agree well with the Bingham model. Yield values in the lava are 1200 and 700 dynes cm (super -2) , and the plastic constants are 6500 and 7500 poises. Laboratory studies in silicone fluid show gas bubbles enhance plastic behavior. In general, lavas must be treated as non-Newtonian fluids; the conditions that may cause different types of fluid behavior in tholeiitic lava are outlined.
