Shattuckite was discovered in Bisbee, Arizona, USA (Shattuck mine) as a pseudomorph
after malachite (Schaller, 1915).
At places the complete transformation of hornblende to chlorite is visible in the form of pseudomorph
left after hornblende.
The combination of these two secretions is thought to allow squid to produce ink of various consistencies, ranging from a diffuse cloud to a substantive pseudomorph
(Boletsky, 1997; Young and Mangold, 2000; Bush and Robison, 2007).
formation from arsenopyrite oxidation using Acidithiobacillus ferrooxidans.
If the interlayer cations with the corresponding portion of silica are successively removed from the pseudomorph
by continuing percolation and degradation, differently ordered kaolinite minerals together with illite or expansible 2:1 phyllosilicate crystallize among the newly formed clay minerals.
In fact, tiger's-eye is cited in many textbooks as a classic example of a pseudomorph
, says Peter J.
They also have the ability to excrete an ink cloud, called a pseudomorph
, which resembles a squid's shape.
Squid possess two options for self-defense: They may eject a large quantity of ink that acts as a smoke screen, or they can choose to darken their color intensely, then release a squid-size, squid-shape pocket of ink called a pseudomorph
, blanch, and jet away, leaving a confused predator grasping at a vaporous facsimile.
This cubic morphology of primary jarosite does not necessarily mean a pseudomorph
transformation from pyrite, since they have the same crystal habit.
Ink Release is observed in several forms: (a) a cloud (n = 25), either diffuse or of interconnecting ink blobs, (b) a single pseudomorph
(n = 9) or two or more consecutive pseudomorphs
(n = 2) that hold their shape, (c) a diffuse puff (n = 6), (d) a long slender rope (n = 2), (e) a short, thin string (n = 2), and (f) alternating with defecation (n = 1).
Impersonating the Manuscript: Cross-Dressed Authors and Literary Pseudomorphs
" analyzes how Spenser, Gascoigne, and Daniel each "reshaped and introduced a new authorial career by developing a literary pseudomorph
that he could supersede" (250), and amply documents that "patterns of authorial emergence .
It takes two basic forms: (a) relatively small puffs either in the form of a pseudomorph
that resembles the size and shape of an escaping squid, or more commonly just a general blackened spot; or (b) large and dense clouds of ink.
