Geology and Mineralization
The Balmat-Edwards district zinc deposits occur in intensely folded,
distorted and deformed Proterozoic metasedimentary rocks of the NW
Adirondack Lowlands, subjected to high temperature and high pressure
metamorphism during the Grenville Orogeny approximately 1.1 billion
years ago. The zinc deposits are hosted in the Upper Marble Formation,
a sequence of shallow water carbonate units characterized by siliceous,
dolomitic, diopside-rich and evaporate-bearing marbles. Zinc orebod-
ies exhibit tabular or pod-like geometries and occupy zones within the
hinges and axial regions of folds and faults associated with the Sylvia
Lake syncline, a major regional scale structure recognized at Balmat.
The Balmat deposits are classified as SedEx-type, commonly defined
as deposits formed from precipitation of metals from brines generated
by evaporation and movement of fluids through carbonate and evapo-
rate-rich rocks in marine sedimentary basins. The fluids/brines leach metals
as they migrate through the sedimentary pile along regional and local
structures and ultimately reach the sea floor where the metals precipitate
as lenses and sheets in favorable structural and stratigraphic settings.
