Rock hardness is a term used in geology to denote the cohesiveness of a rock and is usually expressed as itscompressivefracturestrength. Terms such as hardrock and softrock are used by geologists to distinguishing between igneous/metamorphic and sedimentary rocks, respectively

genesis of the zinkgruvan stratiformzn-pb-ag deposit and

Apr 01, 2017· Based on the cessation oflimestonedeposition, the lack of coarse-grained or thick-bedded volcaniclastic facies and the deeper marine environment inferred for the thick pelitic succession of the overlying Vintergölen group (Hedström et al., 1989, Kumpulainen et al., 1996), it is likely that following deposition of thelimestone, and prior to

compressive strength of rocks- petrowiki

Jun 04, 2015· Estimatingcompressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxialcompressive strength(C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rockstrengthprovided by C 0. C 0 can be estimated from porosity or sonic velocities, but …
