Fault gouge in a schist on Bailey Island, Maine. Fault gouge is a type of fault rock best defined by its grain size. It is found as incohesive fault rock (rock which can be broken into its component granules at the present outcrop, only aided with fingers/pen-knife), with less than 30% clasts >2mm in diameter. [1]
The gauge (in American English or more commonly referred to as bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) and other necessary parameter to define in general a smoothbore barrel (in difference of caliber what define a barrel with rifling and there cartridge).
1904 cartoon warning attendees of the St. Louis World's Fair of hotel room price gouging. Price gouging is a pejorative term used to refer to the practice of increasing the prices of goods, services, or commodities to a level much higher than is considered reasonable or fair by some.
Fault gouge is an unconsolidated and incohesive type of fault rock consisting almost entirely of finely crushed material. Varieties that have a large clay mineral content are known as clay gouges . Pseudotachylite
Sometimes a distinction is made between fault gouge and fault breccia, the first has a smaller grain size. [1] Zones of fault breccia and fault gouge in rocks can be a hazard for the construction of tunnels and mines, as the non-cohesive zones form weak places in the rock where a tunnel can collapse more easily.
Dial indicator, also known as a dial test indicator, dial gauge, or probe indicator an instrument used to accurately measure small linear distances. Feeler gauge: a simple tool used to measure gap widths. Gauge block, (also known as a gage block, Johansson gauge, slip gauge, or Jo block) a precision ground and lapped length measuring standard.
To give an example of the difference, consider using a cone shape gauge to score a .22 Long Rifle bullet hole (with the .22 LR having a bullet diameter between 5.7 to 5.73 mm), the tip of the scoring gauge might have a diameter of 5 mm and a gauge base measuring 5.6 mm in diameter.
It is also given as inches of water gauge (iwg or in.w.g.), inches water column (inch wc, in. WC, " wc, etc. or just wc or WC), inAq, Aq, or inH 2 O. The units are conventionally used for measurement of certain pressure differentials such as small pressure differences across an orifice, or in a pipeline or shaft, [ 1 ] or before and after a ...
