One of the more popular mineral locations for upstate New York rockhounds this year was Rose Road off Route 3 in Pitcairn, a daily fee site owned by Mr. Richard LaPlatney who lives at the property. Although the silicate skarn mineralization flanking the Grenville age white marble hill has been visited by mineral collectors dating back to 1880’s the location seems to have been rejuvenated after Walter highlighted the mineralogy and collecting history in his 2007 book “Field Collecting Minerals in the Empire State”.
The major “digging” there this year was focused on the first site encountered after passing LaPlatney’s home just off of Rose Road. At first glance the exposed rock seems to be dominated by lavender diopside, calcite, albite and red brown phlogopite.. A Scanning Electron Microscopy/Energy Dispersive Analysis (SEM/EDA) of the lavender diopside indicated elevated Ti, likely substituting into the Mg spot in the lattice to generate the lavender color (S. Chamberlain, pers. comm.). There is also less Fe in the purple diopside than in the green version found just a few hundred feet farther up the road.
