Mar 3, 2021Limestones are usually considered brittle and are therefore likely to have higher Young's moduli than other sedimentary rocks in a basin (Afşar et al. 2014 ). As such, limestones can often become fractured following deposition and burial, thereby enhancing their porosity and permeability (Dashti et al. 2018; Li et al. 2018 ).

Our observations showed that strain localization may develop at relatively small axial strains of ~1%, in both the brittle faulting and transitional regimes. In Majella limestone (porosity = 31%), the localized deformation involved both shear and compaction. Compaction bands were only observed in less cemented samples of Leitha limestone.

Limestone was most famous during the 19th and 20th century as many public buildings and structures were made from limestone. The Great Pyramid of Giza which is one of the Seven Wonders of the World is also made of limestone. Kingston, Ontario, Canada is nick-named the 'Limestone City' as many buildings are constructed from limestone.

The different forms of tenacity are: Brittle - If a mineral is hammered and the result is a powder or small crumbs, it is considered brittle. Brittle minerals leave a fine powder if scratched, which is the way to test a mineral to see if it is brittle. The majority of all minerals are brittle. An example is Quartz.

It spawns typically in streaks or ...
