Amygdular camptonite dikes from Mount Jo, Mount Marcy Quadrangle, Essex County, New York Available to Purchase

Howard W. Jaffe
Published: 01 December 1953
American Mineralogist (1953) 38 (11-12): 1065–1077.
...Howard W. Jaffe Abstract Three small, amygdular camptonite dikes intrude the Marcy anorthosite in Mount Jo, Mount Marcy quadrangle, Essex County, N. Y. They show a northeasterly strike, 80° to 90° dip, and are 13 to 20 inches thick. They are similar to the post-Ordovician camptonite dikes from...

Cooling and unroofing rates for four samples from the Adirondack Mountains, New York, based on their apatite fission-track (AFT) and (U-Th)/He ages and respective closure temperatures. High Peak samples include Whiteface Mountain (41), Mount Marcy (42) and Sawteeth Mountain (37); Schroon Lake sample (43) is from the southeastern Adirondacks; 1 σ error bars are indicated for each type of cooling age. The AFT ages for Whiteface, Marcy, and Schroon Lake were previously published in Roden-Tice et al. (2000). Numbers in parentheses correspond to table 1.

Age versus elevation plot containing both apatite fission-track (AFT) and apatite (U-Th)/He (AHe) ages determined for samples in Mount Marcy profile. The inferred range of possible cooling paths (in gray) and regression lines discussed within the text (solid and dotted lines) are outlined for each data set. Note the apparent overlap of the bottom portion of the AFT profile with the upper portion of the AHe profile, where the region of acceptable cooling paths flattens considerably.
