The sillimanite-potash feldspar isograd
in Western Maine, U.
Rios and Takasu (1999) consider that at the staurolite isograd, [X.
5 kbar), and if we were to encounter this reaction in the field, it could be used to define the kyanite isograd.
The sharp offset in the andalusite-in isograd assists mapping the stratigraphic contact within the metamorphic aureole.
Metamorphic reactions and isograds related to this intrusion were documented by Jamieson et al.
The contact aureole of the South Mountain Batholith in Halifax, Nova Scotia: geology, mineral assemblages, and isograds.
Folding of metamorphic isograd surfaces above a footwall ramp would account for the observed trends.
DELINEATING THE EFFECTS OF LATE PALEOZOIC DEFORMATION OF MIDDLE PALEOZOIC METAMORPHIC ISOGRADS WITH GEOTHERMOBAROMETRY.
This zone lies in a fold nose and west limb of an iron formation on the south grid less than 1 km from the cordierite in metamorphic isograd
map for gold, copper, molybdenum, and silver will be constructed from this data.
