From ancient times until today, natural stones have played...

... Microstructural properties The micro-structural properties considered are miner- als (quartz, clay or any specific minerals of concern) and grain sizes or block sizes which play a significant role in oil and gas unit processes. 2.3.1 Mineralogy Mineralogy plays a significant role in the petroleum industry during...

... abrasivity is a physical parameter which influences the sawing and machinability of rocks in general. Many authors have studied its relationship with textural parameters, grain size being one of the most studied, so that the bigger the grain size, the bigger the abrasivity (Birle & Ratterman, 1986...
