	Theory of the Earth: Chapter VII. Opinions examined with regard to Petrifaction, or Mineral Concretion
		If again he means to explain petrifaction in the usual way, by a chemical operation, in that case, the application of his polished surfaces, so as to cohere, cannot take place until the dissolved body be separated from the fluid, by means of which it is transported from place to place in the mineral regions.
		Petrifaction is a subject in which mineralogists have perhaps wandered more widely from the truth than in any other part of natural history; and the reason is plain.
		But it is this author's explanation of that petrifaction which is our present object to consider; and, as he is so particular in giving us his theory upon the subject, it is easy to detect the error of his reasoning.

	Petrifaction - Wikipedia, the free encyclopedia
		In geology, petrifaction or petrification is the process by which organic material is converted into stone or a similar substance.
		Petrifaction is also a common theme in folklore and mythology, and is associated with the legends of Medusa the Gorgon, the basilisk, and the cockatrice, among others.
		Petrifaction is a major plot element in Harry Potter and the Chamber of Secrets.

	Petrifaction
		A rock created by petrifaction; an organic object infiltrated with mineral matter and preserved in its original form.
		A process of fossilization whereby organic matter is converted into a stony substance by the infiltration of water containing dissolved inorganic matter (e.g., calcium carbonate, silica), which replaces the original organic materials, sometimes retaining the structure.Syn:petrification.
		English words defined with "petrifaction": Anthropolite ♦ Corallite ♦ Lapidification ♦ Petrifactive.

		Another common mode of preservation of plants is petrifaction, which is the crystallization of minerals inside cells.
		One of the best-known forms of petrifaction is silicification, a process in which silica-rich fluids enter the plants cells and crystallize, making the cells appear to have turned to stone (petrified).
		Petrifaction may also occur in animals when minerals such as calcite, silica, or iron fill the pores and cavities of fossil shells or bones.

		In the study by the Japanese scientists, we have a case of permineralization, where the silica spheres were adhering to the surfaces of the wood tissue.
		In other words, the formation mechanism of silicified wood from the Noto Peninsula is considered the same as that of naturally fallen and experimental silicified wood associated with the hot spring water of this study.
		In the Miocene samples, some of the vessel walls were replaced with silica, however, there was none of this replacement noted in the experiment, thus there was no "petrifaction." The Sedimentary Geology article is unclear on the amount of replacement noted in the Miocene samples, therefore I contacted one of the authors of the article.

	To See or not to See. The ambiguity of Medusa in relation to Mulisch's The Procedure by Laurens de Vos
		According to the psychoanalytic explanation, the subject is struck dumb by the sight of the female genitals.
		The image of petrifaction symbolising an erection may seem a bit farfetched – bearing in mind that the metamorphosis of organic beings into inorganic rock is a very common theme in classical mythology –; it still touches on the heart of the ambiguity that to my mind characterises the whole Medusa figure.
		The caution and guardedness, carried to the utmost limit, oblige the person involved to take on the unconditional role of subject; he is the seer, yet, if he turns into the object of the act of seeing, he is irretrievably lost.

		The dictionary defines petrifaction simply as, “To become stony.” (http://dictionary.reference.com/search?q=Petrify) Petrifaction, also called permineralization, of wood allows wood to change its composition by chemical reactions and be preserved as a collection of minerals.
		The process of petrifaction is fairy simple, and it has been theorized that the petrifaction process can take only a few hundred years.
		The process of petrifaction begins when a tree dies and is buried by either mud, sand or, most commonly, volcanic ash.

	The American Goliah (Site not responding. Last check: 2007-10-30)
		The general impression is, that it is a petrifaction of one of those large human beings of which all of us have heard so much in our youthful days, and have read accounts of in maturer years—not here, but somewhere else.
		Now, these materials are, in cases of petrifaction, brought to the spot and deposited by action of the water—precisely such an operation as forms strata of rock; should it not produce the same effect in the appearance of successive layers or strata in the subject of petrifaction?
		With reference to the other objection to the theory of petrifaction, viz:—that the members of the body are conjoined and not detached—it is sufficient to say, from the very nature of the operation of petrifaction, portions of the body lying in contact would necessarily be conjoined and filled up.

	Petrified Wood
		Petrified wood has been preserved for millions of years by the process of petrifaction.
		Petrifaction, one kind of fossilization, occurs when chemical changes cause a mineral to grow, grain by grain, in place of the original tissues of the animal or plant.
		Growth rings, like those that can be seen in the wood of trees living today, show clearly in those polished surfaces of petrified wood.

		The criteria cited as diagnostic for the American petrifaction species of Lepidocarpon were found to fail as bases of discrimination when 400 specimens of Lepidocarpon found in coal balls of Pennsylvanian age were studied.
		All previously described American and British petrifaction taxa fall within (or not significantly beyond) this range of variability of a single species as determined from this sample.
		Additional evidence concerning the 3-dimensional sporophyll structure of this one species of Lepidocarpon and the configurations obtained by certain planes of section through it have served to demonstrate that Illiniocarpon cadyi is in reality a taxon based on sectioned structures of the sporophyll of this Lepidocarpon species.

		The word petrifaction means 'turned to stone', and that is literally what happens with this type of fossil!
		Coprolite is preserved animal facies, and can be a petrifaction, impression or compression.
		Coprolites often contain preserved plant matter and sometimes provide 'glimpses' of former plant communities, as several plants from the area that the animal was grazing in may be preserved.

		In some cases, the structure of the organism's soft tissue is even preserved.
		When petrifaction occurs, mineral rich fluids slowly seep into the cells of an organism and crystallize, displacing the original organic matter.
		When an organism is buried in mud, the minerals that make up its hard parts can dissolve and be replaced by different minerals such as calcite or silica.

		A parody of tragic melodrama, this "tomfoolery" unleashes the romance of love and vengeance with no such civilized restraint.

		Israeli society may be the only society in the world that keeps asking itself: "Who are we?" "What is Israeli identity?" "Are we still Jews/Zionists?" "Do we have a culture?" Left-wing and Right-wing supply a sense of identity, a superficial awareness of tribal belonging and a class consciousness.

		CHINA, Oct 22, 2001 (AsiaPort via COMTEX) -- The general manager at China petrifaction, Li Yizhong discloses that China petrifaction will cut the oil refining ability at 5 million tons in the coming 3 years to reduce the cost, when attending the foundation ceremony of the joint venture between China petrifaction and BASF in Nanjing.
		He says that the aim of the company is to close up a group of oil refining factories whose scopes are small and efficiencies are very low.
