Growth of Silica Sinters: Laboratory and Field Studies ...
Silica sinter occurs around many hot springs worldwide including those in New Zealand. There is great textural variability in the sinter deposits. Much of this variability is due to difference in physical and chemical conditions in and around the hot spring.

Experimental studies on New Zealand hot spring sinters ...
To study the rate of growth of sinters in New Zealand hot springs, field experiments were conducted in seven geothermal areas. At Wairakei, fanshaped subaqueous deposits of amorphous silica grow rapidly (350 kg a 1 m 2 of drain wall) and are composed of silicified filaments with subordinate bacillus and spirilliumshaped organisms.
