Relationships between elements (amount above 1%) and mechanical properties: (a) silicon, (b) aluminum, (c) calcium, (d) ferrum, (e) magnesium, and (f) potassium. RFT: rock fracture time; MS: maximum stress; RS: reflection stress; YM: Young’s modulus; PR: Poisson’s ratio; black point: Upper Triassic; red point: Lower Permian.
