Porcelain Springs


Influencing a Landscape


The milky color of the mineral deposited here inspired the naming of Porcelain Basin and Porcelain Springs.  The mineral, siliceous

sinter, is brought to the surface by hot water and forms a sinter "sheet" over this flat area as the water flows across the ground and

the mineral settles out.  This is the fastest changing area in the Norris Geyser Basin, and siliceous sinter is one of the agents of 

change.  If the mineral seals off a hot spring or geyser by accumulating in its vent, the hot, pressurized may flow underground to 

another weak area and blow through it.


Siliceous sinter also called geyserite.  Deposits usually accumulate very slowly - less than one inch (2.5 cm) per century - and form

the geyser cones and mounds seen in most geyser basins.

In addition to the text there is a picture of siliceous sinter also called geyserite.
