About us…

The Mineralogical Society of Southern California is dedicated to the dissemination of a general knowledge of the mineralogical and related earth sciences through the study and collecting of mineral specimens. Organized in 1931, it is the oldest mineralogical society in the western United States.
The MSSC is a scientific non-profit organization that actively supports the Pasadena City College Geology Department, its associated Dana Club,, and the Field Science Scholarship Fund. Support is also given to the San Bernardino County Museum of Natural History and Mindat.
The MSSC is affiliated with the California Federation of Mineralogical Societies and American Federation of Mineralogical Societies.

About the Program: Do Rocks Start Fires?

Presented By Dr. George Rossman 

Dr. Rossman will discuss a project with which he was involved that considered the possibility that rocks rolling down a mountain could collide and give off hot fragments that would start fires. This study took place in the mountains on the north side of Mount San Jacinto. It was in response to an actual fire that occurred in that region. The study involves characterization of the weathering phases on the rocks and measurement of the temperature of the fragments ejected when rocks collide. He will highlight an extensive study of this possibility and some legal ramifications that ensued. 

George Rossman is currently Professor of Mineralogy at the California Institute of Technology where he has worked for the past 48 years. He has a Ph.D. in inorganic chemistry from the Caltech where his studies involving molybdenum cyanides and polymerized iron compounds had little to do with minerals or geology. He has authored or co-authored over 360 papers in mineralogy, chemistry, and materials science. The tourmaline species, rossmanite, published in 1998, was named in recognition of his studies of the color and spectroscopy of tourmalines.
