Swelling clay minerals with a three-layer 2:1 (TOT) structure whose interlayers are mainly occupied by Na + or Ca 2+ hydrated cations and water molecules (from Ancient Greek σμηκτός (smēktós) 'lubricated'; from σμηκτρίς (smēktrís) 'walker's earth, fuller's earth'; lit. ' rubbing earth; earth that has the property of cleaning ').
On the other hand, compression stress acts horizontally, parallel to the surface of the earth. Tension stress causes rocks to be pulled apart and is associated with the lengthening of a surface. Shear stress acts in the direction against motion as two parallel planes move against one another. [4]
Meaning Origin language and etymology Example(s) -iasis: condition, formation, or presence of Latin -iasis, pathological condition or process; from Greek ἴασις (íasis), cure, repair, mend mydriasis: iatr(o)-of or pertaining to medicine or a physician (uncommon as a prefix but common as a suffix; see -iatry)
One way in particular that joints can be formed is due to fluid pressure, as well as at the crest of folds in rocks. This occurs at the peak of the fold or due to the fluid pressure because a localized tensile stress forms, eventually leading to jointing. [2] Another way in which joints form is due to the change in the weight of the overburden ...
In geology, the term compression refers to a set of stresses directed toward the center of a rock mass. Compressive strength refers to the maximum amount of compressive stress that can be applied to a material before failure occurs.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Meaning: a prefix used to make words with a sense opposite to that of the root word; in this case, meaning "without" or "-less". This is usually used to describe organisms without a certain characteristic, as well as organisms in which that characteristic may not be immediately obvious.
Transtension is the state in which a rock mass or area of the Earth's crust experiences both extensive and transtensive shear. As such, transtensional regions are characterised by both extensional structures (normal faults, grabens) and wrench structures (strike-slip faults). In general, many tectonic regimes that were previously defined as ...
