The objective of this research was to develop an understanding of the fundamental processes involved in the formation of geothermal scales. One step toward this understanding involves compiling available data on brine composition and temperatures. Also, chemical and mineralogical analyses of scales that have precipitated from these brines under known and controlled conditions are necessary. To obtain especially documented samples, field tests were developed and performed to simulate the scale-forming processes. Laboratory studies of the thermodynamic and kinetic characteristics of silica-water reactions were carried out. Silica was emphasized because it is the most common, pervasive, and bothersome scale component. The resulting insights into the physical chemistry of the scale-forming processes are presented here together with some of their implications for scale prevention.
