...Denver Stone; D. Choudari Kamineni Abstract Fractures in the Eye–Dashwa pluton near Atikokan, Ontario can be subdivided on the basis of their filling materials. These materials include aplite, epidote, chlorite, and gypsum–carbonate–clay, listed in order of decreasing age established from...

...) surveys, which was done in this study for the Eye-Dashwa Lakes pluton near Atikokan, Ontario. Susceptibility logs of cores directly link alteration to systematic changes in the amount and composition of magnetic minerals. The surficial distribution of alteration zones was originally estimated from...

...P. Lapointe; W. A. Morris; K. L. Harding Abstract Magnetic susceptibility measurements on cores from boreholes in the Eye–Dashwa lakes pluton, an Archean granitic pluton near Atikokan, Ontario, give a quantitative evaluation of the alteration level of these rocks. The histogram of the 5406 magnetic...

... as that for gypsum and anhydrite (+8%0) from the Precambrian pegmatite of Grenville Province in Ontario and gypsum (+7.1%0) from the Eye-Dashwa lakes pluton formed as a result of hydrothermal interaction of pore water in fractures and rockforming minerals (Kamineni, 1983). From this account as well as the geological...

... deformation. Also Kamineni et al. (1993) found palygorskite-filled fractures as an alteration product of epidote in the Eye-Dashwa Lakes pluton and the fibres ranging in length from 3 to 50 μm. In contrast to the above described vein-filling type, the sedimentary palygorskite is much smaller in size...
