Areas of Interest:

(1) A study of chemical gradients in coexisting Basaltic and Trondhjemitic Magmas. We have discovered a xenolith of Na-rich Lockatong argillite that fused around its margins when immersed in the magma of the Palisades Sill. The complex chemistry of the fusion zone, now represented as a pyroxene trondhjemite, indicated diffusion of ions across the liquid-liquid interface. Slices, cut perpendicular to the long axis of a core containing the 200 million year old contiguous rocks, were chemically analyzed for major, minor, and trace elements including REE's. What are the relative diffusivities of these ions in the coexisting melts? Why didn't the two melts physically mix?

(2) The petrogenesis of leucocratic dike-like rocks in the Palisades Sill, and Laurel Hill intrusive. Our chemical data, including chondrite-normalized REE plots, indicate that many of the leucocratic dikes in these intrusives are derived from fused sediment, and are not differentiates of the Palisades magma, or any other basaltic magma. We are interested in understanding the physiochemical factors that play a role in sediment fusion.

(3) Environmental GIS(Geographical Information Systems) studies of Staten Island: i.e., Ground water studies , surface water studies , soil and rock studies.; slope studies and cancer studies.

(4) Pedagogy: Improving laboratory instruction by using the latest technology and innovative methods.

Project Themes :

1) Petrogenesis of the Staten Island Metaperidotite using Cr-Spinels as a petrogenetic indicator.
