Any physical or chemical change in a rock or mineral subsequent to its formation. More mild and local than metamorphism.
Any physical or chemical change in a rock or mineral subsequent to its formation. Areas of rock and/or mineral alteration are commonly associated with base and precious metal or mineral deposits and are often larger than the orebody itself.
Refers, within active volcanoes, to conversion of volcanic rocks to clay and other minerals through chemical reaction with circulating hot acidic water
A change made after production has started.
alteration of a rock/mineral by geological forces
The change of a being from one qualitative state to another.
A change in, or addition to, an existing building
Any changes made by a tailor to improve the fit of a garment, common with men's suits.
A change made by the client after any part of the production process has begun. Usually billed as an extra charge.
an event that occurs when something passes from one state or phase to another; "the change was intended to increase sales"; "this storm is certainly a change for the worse"; "the neighborhood had undergone few modifications since his last visit years ago"
the act of revising or altering (involving reconsideration and modification); "it would require a drastic revision of his opinion"
a change in a road's sidelines
a change or mutation in the physical structure of a gene that interferes with the gene's normal functions
a change that affects (or could affect) access to or usability of a facility or a part of a facility

an unauthorized change in an instrument that purports to modify in any respect the obligation of a party, or it could be an unauthorized addition of words or numbers or other change to an incomplete instrument relating to the obligation of a party
chemical and mineralogical changes in a rock mass resulting from the passage of fluids or increases in pressure and temperature that is related to emplacement of economic mineralization
Changes in the chemical or mineralogical composition of a rock, generally produced by weathering, pressure and hydro-thermal action.
It is the process where a rock or a mineral is transformed into another one.
Any change or modification to a building's construction. See Addition.
A change to the information in a record after it is signed.
The Adjustment made due to the changes of the policy.
An unauthorized modification of a contract by one of the parties to the contract. The alteration is considered material when it affects the rights of the parties to the contract. If the alteration is intentional and material, it will be treated as fraud and the innocent party may void the contract at his or her option.
A change from manuscript copy made at the proofreading stage. This is not the same as a correction, which is made to eliminate a typesetting error. Alterations at this stage substantially increase production costs.
A change resulting in something that is different from the original.
the physical or chemical change in the composition of rock
Change in copy of specifications after production has begun.
A change to any part or to the whole of a structure that is not ordinary repairs.
A change in the boundaries of an activated zone or subzone.
Any physical or chemical change in a rock or mineral subsequent to its formation. Milder and more localized than metamorphism.
n. Change or modification.
A change made to an executed contract which has not been approved by the parties to the contract. An alteration may constitute fraud if it has the impact of significantly affecting the rights of a party to the contract and was intentionally carried out by another party. If fraud is found, the innocent party may void the contract.
A change in the chemical and mineralogical composition of a rock caused by hydrothermal fluids.
A change that has been made by a customer after copy has been sent to the printer.
Any change made by the customer after copy or artwork has been given to the service bureau, separator or printer. The change could be in copy, specifications or both. Also called AA, author alteration and customer alteration.
Chemical changes in minerals occurring after a mineral is formed; typical of the reaction between mineralizing fluids and host rocks, and the surface weathering of rocks. Common types (and their characteristic minerals) include albitization (sodium feldspar), argillization (clays), chloritization (chlorite), potassic alteration (potassium feldspar and biotite), propylitization (epidote), sericitization (white mica), and silicification (quartz).
An alteration is a change to a building or facility made by, on behalf of, or for the use of a public entity, a lease to or occupancy by a state agency, a public accommodation or commercial facility, that affects or could affect the usability of the building or facility or part thereof. Alterations include, but are not limited to, remodeling, renovation, rehabilitation, reconstruction, historic restoration, changes or rearrangement of the structural parts or elements, and changes or rearrangement in the plan configuration of walls and full-height partitions. Normal maintenance, reroofing, painting or wallpapering, or changes to mechanical and electrical systems are not alterations unless they affect the usability of the building or facility. 3.5.10
Alteration, as applied to a building or structure, means a change or rearrangement in the structural parts or in the exterior facilities, or an enlargement, whether by extending on a side or by increasing in height, or the moving from one location or position to another.
Changes in the chemical or mineralogical composition of a rock, generally produced by weathering or hydrothermal solutions;
An unauthorized operation performed on a document after it has been validated that changes its language or legal meaning, specifically the terms in a negotiable instrument, without knowledge or consent of the parties involved.
Chemical and/or mineralogical changes in a rock that occur due to weathering or reaction with hydrothermal fluids.
Any physical or chemical change in a mineral or rock subsequent to original formation; usually results in the formation of new minerals or in textural changes in the rock. Amphitheater A very large concave hollow in a canyon wall. Annual A plant that germinates, flowers, and sets seed in a single growing season.
A change in a mechanical system that involves an extension, addition or change to the arrangement, type or purpose of the original installation.
Changes or modifications to a building or structure.
Change in copy or specifications made after production has begun.
