"Lake Iron Nodules in New England An Historic Massachusetts Geologic Resource Past, Present, and Future"
by Jon Higgins
Jon will be bringing mineral samples of lake iron nodules he obtained up in the Canadian Maritimes. Historically, Massachusetts used to have literally tons of these at the bottom of lakes and some ponds, but he was not able to find any locally anymore. His presentation will discuss his research findings. He is looking forward to presenting, not only because its of sincere interest to him but also because this little mineral has a story that needs to be heard. Jon is the founding member and chairman of the Powow River Watershed Association, a now closed 501c(3) organization that ran for ten years up in Amesbury, MA. He has a B.S. UMass Amherst in Geology and a M.A. Boston University in Geology with a Masters Thesis "Hydrogeologic Assessment and Remediation of a Diesel Fuel Release. He also has a Ph.D. Candidate Studies Univ. of New Hampshire Natural Resources and Earth Sciences (NRES) - Earth Science - completed course work, Proposal Defense and a few years of independent research on the relationship of arsenic and phosphorus to the iron cycle in freshwater environments with a focus on Lake Iron Nodules Otherwise, he has been a consulting geologist in the water resources and environmental assessment field for over 30 years now. Most of his time has been spent in New England, Massachusetts in particular. He started Higgins Environmental Associates in January 1999 and looking back, is thankful for all the really good clients he happened to work for and with. Jon published a paper on "The Heterogeneity of Phosphorus in Aquatic Sediment" and filed three patents (one full, two currently provisional) - all based on his doctoral research on Lake Iron Nodules. Jon traveled and researched extensively on the history, occurrence and biogeochemistry related to lake iron nodule
This month we will talk about dangerous and/or poisonous minerals we should not collect. Some of these minerals are popular because they are either colorful or fibrous. These include asbestos minerals, orpiment and realgar cyanide based minerals, cinnabar a mercury based mineral and a few others. I will show samples of each in plastic boxes so everyone can see what they look like. Also part of collecting or handling minerals should always end with a good hand washing. And most important of all please don’t forget to bring something
for us to identify and talk about. See you there!!
REFRESHMENTS WILL BE SERVED AFTER A BRIEF BUSINESS MEETING. CONTRIBUTIONS TO THE REFRESHMENT TABLE ALWAYS WELCOME! NO PEANUT PRODUCTS, PLEASE.
