Research in New Jersey Highlands

In the last few years Colgate students and I have begun to work on the Proterozoic
Franklin Marble of the New Jersey Highlands with Richard Volkert of the NJ
Geological Survey. The marble hosts of a number of small iron ore deposits and the
world-class zinc deposits at Franklin and Sterling Hill.
Four Students have been involved in this research. Mike Meredith ('03) and
Erika Rader ('07) focused on quantifying metamorphic conditions of the marble by
examining petrology and the fractionation of carbon isotopes between calcite and
graphite. Bret Doverspike ('03) and Adam Mansur ('05) worked on understanding the
genesis of the iron and zinc ore deposits. Erika also discovered an occurrence
of the rare borosilicate Serendibite in the Franklin Marble of Orange County, NY.
