Granite of two micas, with granulate average, yellowish coloration and fast profiróide trend. The texture is hipautomórfica to granular xenomorphic, in which the constituent crystals of the rock discloses subédricas morphologies to anedricas.

 

Resistance to ice

At the end of the 240 cycles of ice-thawing the test tubes had not disclosed sensible alterations in the colour nor in the structure. The decrease in the volume was not significant. The fast increment in the value oh the resistance to the flexion corroborates the not iced behaviour of the rock.
