Rochester Academy of Science Mineral Section

Since 1884 members of the Rochester Academy of Science Mineral Section have enjoyed collecting and learning about minerals, as well as exploring related geoscience topics.

We are a Charter Member Club of the Eastern Federation of Mineralogical and Lapidary Societies.

Our By-laws

During the academic year 2021-2022, we are meeting virtually at 7:00 pm on the 4th Tuesday of most months. There are no meetings December, April, or June through August.  Members are informed by email of meeting events and when there are changes. The RAS Bulletin announces the meeting dates and topics.  Members are reminded by email of each event and when there are changes.

PAST MEETING: May 24. Dr. Howard Heitner  presented Pseudomorphs, Trickster Mineral Specimens.  

The word pseudomorph was first used by Hauy in 1801. In Greek it means “false shape.” A pseudomorph is a mineral that has the external crystal shape of another mineral. The subject of pseudomorphs was first written about in detail by the 19th century German mineralogist Johann Blum. In 1982 they were classified by the mineralogist Strunz.  There are various theories of how pseudomorphs form. In some cases the second mineral is similar in composition to the original mineral. In those cases the mechanism is a chemical reaction. In other cases the two minerals are not similar and the mechanism of pseudomorph formation is more complicated. There is still controversy about the formation of some pseudomorphs. The talk is illustrated with pictures of both common and rare pseudomorphs. 

Dr. Heitner is a retired chemist and has been an active  collector of minerals for 60 years.  

PAST MEETING: March 22.  Dr. Timothy McConnochie discussed the past and present climate of Mars.. He is a Research Scientist with Space Science Institute (http://spacescience.org) and a Participating Scientist on NASA's Mars 2020 Perseverance Rover mission (https://mars.nasa.gov/mars2020).  See the recorded talk here.

PAST MEETING: February 22.  Derek Yoost on Microstructures in Meteorites and their Relation to the Formation of the Solar System.  See the recorded talk here.

The symposium has become a world-renowned gathering of people interested in minerals since 1973.  It is held under the aegis of the Rochester Academy of Science in Rochester, New York. Over several days in April,  the event features technical sessions, special lectures, workshops, auctions, an exhibit hall, and a dealers hall. Due to the covid-19 pandemic  the symposium has become a  virtual event.  For 2022, the program is again virtual, from  Friday evening, April 8 to Sunday, April 10. 

Registration is required.  Information is available here: https://bit.ly/eRMS2022

Barton and Hooper Garnet Mines Field Trip 

by Paul B. Dudley

Garnet is the New York State mineral.  The Gore Mountain area in the Adirondack Mts is noted for its garnet amphibolite (a metamorphic rock), which is rich in a variety of garnet types. 

Amazing Pyrite Shapes of Huanzala, Peru

by Bob Morgan

A detailed look at the myriad crystal shapes exhibited by pyrite from Huanzala.  The beautiful crystals are a feast for the eyes.  Enjoy, even if you don't understand the descriptions!

                        Science Exploration Days 

Organized by the Central Western Section of the Science Teachers Association of  NYS, this event occurred annually in May at St John Fisher College from 1971 through 2019, halting in recent years due to the covid-19 pandemic.  The event featured workshops for students during the day and the exhibit hall was open to the community in the evening.  All of the Academy sections were represented in the exhibit hall and in addition, some members gave presentations during the classroom sessions.  Volunteers at the mineral table enjoyed giving demonstrations, answering questions, and giving away samples.  Perhaps we will do this again in 2023!

                       Monroe County Winterfest

In midwinter, several sections of the Academy participate in this popular county event at  Mendon Ponds Park.  Mineral club volunteers display local and NYS minerals along with a poster of the glacial geology of the park.  We join with  the Fossil and Astronomy section volunteers in the Cobblestone House.  See  Monroe County's Winterfest webpage.

                              ADK Outdoor Expo

Another community event in Mendon Ponds Park that the Mineral Section participates in, occurs in the summer.  It is organized by the Genesee Valley Chapter of the Adirondack Mountain Club.  We share covered tables and space with Fossil and Astronomy sections along the path to the beach and use our displays to share stories about natural history with the visiting outdoor enthusiasts.  See ADK's Expo FaceBook page.
