<Find out how nature might grow big, clear, perfect crystals in an environment of rapidly dwindling thermal energy when Professor David London visits campus on Monday, March 15.>
London, a Mineralogical Society of America Distinguished Lecturer, is a geology professor and director of the Electron Microprobe Laboratory at the University of Oklahoma.
His talk will address how the understanding of the origins of gem-bearing granitic pegmatites has been turned inside out in recent years.
“We now believe that the thin, intrusive dikes that host complex mineral textures, giant crystals of quartz and feldspars, and gem crystals of aquamarine, tourmaline, and topaz form quickly from silicate melt at low temperatures,” said London.
London will make a presentation suited for a general audience at 11:15 a.m. He’ll give an additional talk at 4 p.m. for an advance audience, including graduate students.
Both presentations will take place in Kittrell Hall, Room 204.

TTU hosts a MSA Distinguished Lecturer every couple of years to give the campus an opportunity to hear talks about recent advances in mineralogy.
