1 Introduction – Mineralogy
All minerals, like all materials, consist of one or more elements, the building blocks of all matter. Some minerals, diamond for example, contain a single element (carbon). Others contain many elements. Some minerals have compositions that vary little in nature. Quartz for example is always close to silicon and oxygen in the atomic ratio 1:2.

Microstructural origins of crushing strength for inherently anisotropic
The dashed lines correspond to the fitting of Eq. (2) by finding m and σ 0 with a least-squares minimization. The inset on the same figure presents the values found for the Weibull modulus m as a function of η. Typical values for parameter m for silicate materials are found in the range [1. 5, 4] (McDowell and Bolton, 1998, Lim et al., 2004).
