INTRUSIONS PART 2: INTRUSIVE ROCK FORMATIONS

Elephant Rock (NE Lower Austria) is an outcrop of the South Bohemian Pluton (central Europe). This batholith is one of the largest intrusions within the Variscan (or Hercynian) orogeny, with a surface of ~6000 km². The rounded “elephant” shape of the granite blocks is caused by spheroidal or woolsack weathering. (© Isiwal, via Wikipedia)
