fissility

Mudstones, on the other hand, are similar in composition but do not show the fissility.

"Shale" denotes fissility, which implies an ability to part easily or break parallel to stratification.

Phyllite has a good fissility (a tendency to split into sheets) and will form under low grade metamorphic conditions.

Fissility refers to the property of rocks to split along planes of weakness into thin sheets.

Shale - exhibits lamination or fissility.

Note that a nuclear explosion does not happen in a nuclear meltdown due to the low fissility of the radioactive components.

To avoid confusion, the name of this mountain was changed to Fissile Peak on September 2, 1930 for its fissility.

Fissility may refer to:

Siltstone, mudstone, and claystone implies lithified, or hardened, detritus without fissility.

Fissility (geology)

Shale is characterised by mm-scale laminations parallel with the bedding, called fissility, and will split along these planes.

With increased pressure over time the platey clay minerals may become aligned, with the appearance of parallel layering (fissility).

Although often mistaken as a shale, siltstone lacks the fissility and laminations which are typical of shale.

Shale can be easily split into thin, mm-scale flakes along the sedimentary bedding, otherwise known as a shaley fissility.

All previous sedimentary structures, such as bedding or fissility, are replaced during the metamorphic processes that generate slaty cleavage fabric.

The fissility in these rocks is caused by the preferred alignment of platy phyllosilicate grains due to compaction, deformation or new mineral growth.

Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility.

The mountain is composed of red slate which is easily divided into thin sheets of uniform thickness; in geological terms this feature is known as fissility.

When shale has been exposed to weathering in a quarry or road cutting it parts easily along the fissility, and with prolonged weathering will degrade into a litter of small paper-thin flakes.

Shale typically exhibits varying degrees of fissility breaking into thin layers, often splintery and usually parallel to the otherwise indistinguishable bedding plane because of parallel orientation of clay mineral flakes.

The lack of fissility or layering in mudstone may be due either to original texture or to the disruption of layering by burrowing organisms in the sediment prior to lithification.

The tectonic forces along a southeast-northwest axis during this folding were what gave rise to the almost upright-standing slate areas, which were also thereby given the fissility that allowed them to be split into thin sheets that would be so important much later on to the local economy.
