Welcome to the Colorado Scientific Society
The oldest scientific society in the Rocky Mountain region
Founded in 1882, the Colorado Scientific Society promotes knowledge, the understanding of science, and its application to human needs, focusing primarily on earth science, but welcoming members with interests in all fields of science. Learn more.

Abstract: In the aftermath of the giant collision resulting in the formation of the Moon, about 4.5 billion years ago, the Earth experienced a protracted time of bombardment by leftover planetesimals. In this talk I will present a new bombardment model of the Hadean Earth that has been calibrated using existing lunar and terrestrial geochemical data. We find that the surface of the Hadean Earth was widely reprocessed by impacts through mixing and burial by impact-generated melt. This model may explain the absence of early terrestrial rocks. In addition, by tracking the magnitude and timing of large collisions, we find that existing oceans would have repeatedly boiled away into steam atmospheres as late as about 4 billion years ago. These findings have important implications for the formation and stability of early habitable environments and the onset of life. Finally, I will discuss recent developments in understanding the effects of collisions on the tectonic evolution of the early Earth, as well as the formation of impact-induced geochemical heterogeneities that could still persist in terrestrial mantle rocks.
My research interests span from the formation and geology of terrestrial planets the moon and asteroids, to the spectroscopy and dynamics of minor bodies and meteorites.
I am an associate with several space missions, including: NASA’s Dawn, Lucy, Psyche, and ESA’s Rosetta, BepiColombo, JUICE.
I have been a fellow at the NASA Lunar Science Institute, the Observatoire de la Cote d’Azur, the German Aerospace Agency, and Padua University. I hold a PhD in Applied Physics from the Pisa University. More details can be found here: http://www.boulder.swri.edu/~marchi/index.html

Family Night at the Colorado School of Mines Geology Museum
An open house at the CSM Geology Museum, hosted by Museum Director (and CSS Councilor) Dr. Bruce Geller.
We’ll have complimentary refreshments (pizza and other food, snacks, treats, non-alcoholic drinks) for everyone. In addition to all the regular features of the museum, there will be some special activities–a mineral & rock scavenger hunt/treasure hunt—one for kids and one for adults. Bring your family, friends, and guests!
Regular Sunday hours of the museum are 1 to 4 p.m. Come early if you like too; our CSS event will begin when the regular museum visitors leave.
Some of the special features always at the museum include:
- Mineral, rock, geology, and fossil displays
- New changing mineral displays every year
- Displays focusing on Colorado’s mining districts
- Gold and silver (and platinum!) displays
- Miss Colorado crown, and a silver pitcher and platter made of Colorado silver
- Colorado State Rock, Mineral, and Gemstone (Marble, Rhodochrosite, Aquamarine)
- Amazonite, Smoky Quartz, and Topaz from the Pikes Peak region
- Meteorite displays, plus Apollo 15 and 17 Moon Rocks
- The Mine Tunnel, including a Fluorescent Mineral Display
- Rare-earth and Critical Minerals Display
- The 1939 Irwin Hoffman murals depicting mining throughout history
- The Museum Gift Shop
The Colorado Scientific Society was founded in 1882 as a forum for the exchange of observations and ideas on the topics of earth science. Our lecture series occurs on the third Thursday of each month, from September through May. Lecture topics largely focus on earth science, and are open to the public. In addition to our monthly lecture series, the society is also active in public service. We fund student research grants, construct and post signs that describe local geologic features, and organize and lead several field trips.
The Colorado Scientific Society usually meets on the third Thursday of the month from September through May at The Shepherd of the Hills Presbyterian Church, 11500 W. 20th Ave., Lakewood CO
Social time is at 6:30; meeting & program at 7:00
(In the summer months of June-August, too many are off in the field.)
