Canada Revisited

Article I wrote for WCGMC News in Oct., 2014

Four of us (Linda Schmidtgall, Bill Chapman, Ken St. John, Fred Haynes) decided one summer trip to eastern Ontario was simply not enough and we returned for 4 days in early September.  The highlight was a return to the Miller Property in Eganville, but we managed to squeeze three other sites into the trip, including a pair of lesser known sites in the Bancroft Chamber of Commerce 2013 collecting book.

We started with a visit to the well known Beryl Pit in Quadeville.  Fred had visited with the Rochester Club in July and since that time the owners (Dave and Renee Paterson) had excavated a significant amount of material in the floor of the pegmatite quarry and piled it outside the quarry. This made for easy pickings for beryl, quartz, tourmaline (var. schorl), cleavlandite, albite, perthite, fluorite, and euxenite. We later learned that we may have taken more than our limit on that last one.  Keep reading to learn why!

Fine, NY for skarn minerals

Article I wrote as “Site of the Month” in WCGMC News, Oct., 2014

         Fine Minerals or Minerals in Fine, NY?

This will be a short report on a small occurrence.   And, perhaps this will be even longer than it truly deserves.  But we cannot expect gem tourmaline, perfect fluorites, or complete trilobites at all our favorite haunts.

Nestled in a depression just off the intersection of Rte. 3 and Rte 58 in Fine, NY is an interesting occurrence of very coarse grained pyroxene (presumably diposide, but possibly augite) and potassium feldspar.  There is associated calcite suggesting that the mineralization may have a skarn origin, but the outcrop exposures don’t appear to permit an unequivocal geologic explanation for the very coarse grained open space filling mineralization.

Titanite is Everywhere

Article I wrote for Oct., 2014 WCGMC News

Who knows the most significant event of 1982?   Could it be:

  • The Epcot Center opens in Orlando, Florida
  • Britian overcomes Argentina in the Falklands.
  • Chariots of Fire wins Oscar for Best Picture.
  • MRI (Magnetic Resonance Imagery) makes its medical debut.

Wrong, wrong, wrong and wrong.  The most significant event in 1982 was when the International Commission on Mineral and Mineral Names (CNMMN) adopted the name titanite and discredited the mineral name sphene. Unlike those other events, the impact was immediate and worldwide. OK, maybe a few of you missed the event, but now you know.

WCGMC flirted with titanite collecting all summer.  Perhaps not as infamous as the cry “It must be an amphibole”, but “ooh, it’s another titanite” was commonly heard in the field this summer.

Devonian Fossils of NY – A Book review

Field Guide to the Devonian Fossils of New York by Karl A. Wilson (Paleontological Research Institute, 2014):  This compact (6” by 9”) spiral bound fieldbook is a update to the1994 PRI publication by David Linsley.  After introductory sections on general Devonian stratigraphy and geology and a section of fossil collecting methods, the book systematically introduces Devonian fossils.  Sections on sponges, corals, bryozoa, brachiopods, mollusks, anthropods, trilobites, echinoderms, and more follow with diagrammatic plates offset by descriptive pages detailing the fossils.  By limiting the species to those found in New York, you are much more likely to identify your finds with this book than with a more inclusive book.  The PRI price is $18 and the book can be obtained online with a modest additional shipping charge.  Mine arrived in 3 days !
