A pseudomorphous crystal, such as a crystal consisting of quartz, but having the cubic form of fluor spar, the fluor crystal having been changed to quartz by a process of substitution.
A mineral whose outward crystal form is that of another species. It has developed via some type of transformation (alteration, substitution, incrustation, or paramorphism) and is described as being ``after'' the mineral whose outward form it has.
A secondary mineral, which has replaced an earlier mineral but retained its shape.
A mineral having the characteristic outward form of another mineral or object it replaces.
Pseudomorph - False form. A crystal of a soluble mineral that has been replaced by the crystal of a usually less soluble mineral.
a crystal having the outward form of another mineral, which it has replaced by substitution
a mineral specimen where the original mineral has been chemically replaced by another mineral, but the outward appearance is still retained
a mineral that has replaced another mineral atom by atom, but it leaves the original mineral's crystal shape intact
an atom by atom replacement of a crystal structure by another crystal structure, but with little alteration of the outward shape of the original crystal
an atom by atom replacement of one mineral by another
an atom-by-atom replacement of one mineral for another, without changing the original mineral's outward shape
an atom by atom replacement of one mineral's chemistry for another
One mineral replacing another but retaining the form of the replaced mineral. Pseudomorphs are many and varied, and highly collectible.
a mineral which has the outward form of another mineral. [AHDOS
in geology, a mineral compound resulting from a process by which the primary mineral component is replaced by another, although the compound maintains constant appearance and dimensions.
In geology, a pseudomorph is a mineral compound resulting from a substitution process in which the appearance and dimensions remain constant, but the mineral which makes up the chief component of the compound is replaced by another. The name literally means False Form.
