According to Ver Straeten (2004), the middle Lochkovian, early Emsian and early Eifelian were times of peak volcanic activity in eastern North America, related to times of increased tectonism in the Acadian orogen.
This geological record reveals the innate sensitivity of large rivers to tectonism; and indeed, geologists can read the sedimentary record and physiography of an ancient river as an evolutionary ledger, which reveals how the passage of tectonic events impacted across its host continent.

Crush resistance of frac sand is dependent upon hardness of grain; grain crystallinity; absence of weak planes that could have developed during tectonism; absence of deep pitting of grains, and absence of authigenic overgrowths on quartz grains (Zdunczyk, 2007), To reduce the presence of weaker grains, the ISO 13503-2 proppants standard for percent clusters is [less than or equal to] 1.0.
