Stratigraphy And Structure Of The Ganson Hill Area: Northern Taconic Allochthon, Michelle Aparisi Jan 1985

Stratigraphy And Structure Of The Ganson Hill Area: Northern Taconic Allochthon, Michelle Aparisi

Geology Theses and Dissertations

The Ganson Hill study area is located in the Giddings Brook Slice of the Taconic Allochthon. It contains rocks of Cambrian(?), Cambrian and Ordovician age. The predominant rock type is slate with subordinate lithologies including quartzite, limestone, micrite, arenite and graywacke. The lithostratigraphy identified in the Ganson Hill area extends from the basal Bomoseen wacke to the Poultney slate. A more precisely defined lithostratigraphy is derived from the study area by the occurrence and recognition of the Middle Granville Slate Formation and the documentation of a second Cambrian black/green boundary. Previous workers have included this formation in different places, in …


A Numerical Approach For Determining The Variable Ascent Velocity Of A Granitoid Diapir, Keith I. Mahon Jan 1985

A Numerical Approach For Determining The Variable Ascent Velocity Of A Granitoid Diapir, Keith I. Mahon

Geology Theses and Dissertations

A mathematical model for granitoid diapirism has been developed that accounts for the time dependent thermal and rheological conditions encountered by the intruding body. This model is derived by the simultaneous solution of the partial differential equations of energy, continuity, and momentum utilizing scaling analysis. The underlying assumption is that deformation of the surrounding country rock is confined to a relatively thin layer with a temperature dependent Newtonian viscosity. When the country rock is modeled as a power-law fluid, the effective viscosity is dependent upon temperature and shear strain rate.
This model allows for realistic temperature gradients within the crust …
