William Peck's Research in the 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.
Mike Meredith ('03) and Bret Doverspike ('03) collect marble samples from near the Franklin Mine, a world-class zinc deposit.
