Identifying Granitoids and Other Granite Rocks - ThoughtCo

Aug 13, 2018 · Granite rock has become so common in homes and buildings that anyone these days can name it when they see it in the field. But what most people would call granite, geologists prefer to call "granitoid" until they can get it into the laboratory. That's because relatively few "granite rocks" out there are truly petrologically granite.

The Hoek-Brown strength criterion was applied to estimate the strength of the rock mass at the Aznalcollar open pit. It was shown that by assuming disturbed rock mass, a good agreement was found between estimated strength values and back-calculated strengths from observed slope failures in the footwall. These values are probably conservative and
