Rock Adirondack

Fig. 8.33 Left, robotic arm with MIMOS II positioned on the rock Adirondack, as seen by the navigation camera of the rover Right. Mossbauer Spectrum (14.4 keV temperature range 220-280 K) of the rock Adirondack at Spirit landing side Gusev Crater, plains. The data were taken at the as-is dusty surface (not yet brushed). The spectrum shows an olivine-basalt composition, typical for soil and rocks in Gusev plains, consisting of the minerals olivine, pyroxene, an Fe doublet, and nonstoichiometric magnetite...

Lahradoriie is the characteristic feldspar of the more basic rock types like diorite. gahbro. andesite or basalt and it is usually associated with some one of the pyroxenes or amphiholes. Lahradoriie frequently shows a heauliful play of iridescent colors due lo minute inclusions of another mineral. However, the labradorescent phenomenon has not been fully determined. The classic location for this mineral is. of course. Labrador, whence its name. Il is a constituent there of the rock anorthosite and is found in the anorthosites of the Provinces of Quebec and Ontario, and in the Adirondack region in New York Stale. 

Figure 19. Carbon isotope thermometry for Adirondack marbles. (19A) Plot of 8 C(calcite) vs. 5 C(graphite). Open symbols are for upper the amphibolite facies NW Adirondacks and closed symbols are for the granulite facies Adirondack Highlands. (19B) Values of A(Cc-Gr) in per mil and resulting isopleths for 675°C parallel the strike of the terrane and, show lower metamorphic temperatures centered on Gouvemeur and increasing towards granulite facies rocks to the SE and to NW. Note outcrop tests at Fish Creek (FC), the Train Wreck (TW) and the Valentine Mine (VM) (from Kitchen and Valley 1995).

There are many different types of mountains. The physical attributes of a mountain range depends upon the angle at which plate movement thrust layers of rock to the surface. Many mountains (Adirondacks, Southern Rockies) were formed along high angle faults. 

InNew York State s Adirondack Mountains — and elsewhere in the Northeast and Canada where the underlying soil and rocks have been unable to neutralize acid rain — hundreds of once-pristine lakes and streams have gradually grown acidic, and the aquatic life they sheltered has dwindled and vanished.
