1871, Thomas Egleston, Catalogue of Minerals, with Their Formulae and Crystalline Systems:

The name simple petrosilex seems to have been confined to the more apparenttly homogeneous felsites, while the term porphyritic petrosilex was given to those rocks supposed to have a base of simple petrosilex or of felsparoid which held enclosed porphyritic crystals.

1884, Harvard University. Museum of Comparative Zoology, Bulletin: Geological series - Volume 1, page 399:

A brief history of the word felsite and its synonyms in different countries (petrosilex, eurite, and ha:lleflinta) will serve to illustrate the unfitness of it and these allied terms for exact petrographical usage.

1896, Arthur Winslow, Charles Doolittle Walcott, Florence Bascom, Contributions to the Cretaceous Paleontology of the Pacific:

nemalite

en-noun

nemalite (usually uncountable, plural nemalites)

From Ancient Greek νῆμα (nêma, “thread”) + -lite.

In the mineral kingdom [Magnesium] is found in a native state, combined with water, though this is not a common mineral. The siliceous hydrate, or nemalite, is still rarer. The carbonate is far more common;[…].

1845 September, “My Cabinet”, in Charlotte Elizabeth, editor, The Christian Lady's Magazine, volume 24, page 264:

The specimens examined by me had the ordinary external characters of nemalite, consisting of adhering fibres of a fine silky lustre, and white colour, with a shade of yellow and partial slight blue or green tinge.

1846 October, Arthur Connell, “Analysis of the American Mineral Nemalite”, in Robert Jameson, editor, The Edinburgh New Philosophical Journal, Exhibiting a View of the Progressive Discoveries and Improvements in the Sciences and the Arts, volume 41, number 82, Edinburgh: Adam & Charles Black, page 388:

Several thousand specimens have been quarried from the serpentine and trap Ridges in New Jersey, under the direction of Professor Leeds of the Stevens Institute. They consist of nemalites, occurring in translucent masses made up of long, silky fibers;[…].

1874 October 17, “New Jersey Minerals”, in Scientific American, volume 31, number 16 (new series), New York: Munn, page 244:

As nemalite and chrysotile are usually found under similar conditions—in the form of veins traversing serpentine—it seems not unnatural that the two allied magnesian fibrous minerals should co-exist intimately mixed in the same vein,[…].

1897 May, F. R. Mallet, “On Nemalite from Afghánistán”, in The Mineralogical Magazine and Journal of the Mineralogical Society, volume 11, number 52, London: Simpkin, Marshall, Hamilton, Kent, page 213:

1995, Revista Brasileira de Geociências, page 79:

The entity of the transcurrence phenomenon has led the author to postulate that the post - orogenic collapse of the marginal basins is accompanied by tectonic rotation and great torsions which have disrupted the Pacific perimeter .

2013, Forese-Carlo Wezel, “The Pacific Island Arcs: Produced by Post-Orogenic Vertical Tectonics?”, in F.-C. Wezel, editor, The Origin of Arcs, page 529:

One of the most intensively studied transcurrence zones is the one following the rim of the North American west coast, where the oceanic Pacific plate is moving northwards relative to the continental American plate.

scalenohedron

en-noun

scalenohedron (plural scalenohedrons or scalenohedra)

scalenohedrons (plural)
scalenohedra (plural)

LL-Q1860 (eng)-Flame, not lame-scalenohedron.wav

Though the hexagonal scalenohedron is derived from the double twelve-faced pyramid, by the development of half its faces, and might be constructed from that figure, it is more readily obtained from the positive or negative rhomboid which may be supposed to be inscribed in the scalenohedron.

1859, James Tennant, Walter Mitchell, Mineralogy and Crystallography: Being a Classification of Crystals According to Their Form, page 408:

By bringing together the rhombohedron and the scalenohedron, as has been done in Fig. 119, it will be noticed that the lateral edges of the two forms have a similar position towards the axes, so that for every scalenohedron there must be a rhombohedron whose lateral edges coincide with the lateral edges of the other form. This rhombohedron is called the inscribed rhombohedron of the scalenohedron.

1866, Josiah Parsons Cooke, Elements of Chemical Physics, page 154:

1907, Benjamin K. Emerson, Joseph H. Perry, The Green Schists and Associated Granites and Porphyries of Rhode Island, US Geological Survey, Bulletin Number 311, page 24,
Other steep scalenohedrons of the principal zone are also often present, sometimes in addition to y, sometimes taking its place.

Calcite crystals show a great variety of habits — acute and obtuse rhombohedra and scalenohedra, prisms, and thin tabular forms.

1940, John W. Evans, George MacDonald Davies, Elementary Crystallography, page 111:

(geometry, mineralogy, crystallography) A polyhedron having twelve sides, each in the form of a scalene triangle, that is topologically equivalent to a hexagonal bipyramid and whose middle section can be said to inscribe a rhombohedron.

Equivalent to Vulcan + -ian. Doublet of volcanian. Compare slightly earlier Middle French vulcanien.

In his six lectures on Volcanos, [Faujas] exhausted the subject, and showed us the difference of the several systems, the Vulcanian, the Neptunian, and the Huttonian, which is the Plutonian, and his own opinion.

1803, Stephen Weston, Praise of Paris, page 58:

The Vulcanian or Plutonian theory, which ascribes the changes on earth's surface to the agency of fire.

1870, Ebenezer Cobham Brewer, Dictionary of Phrase and Fable, page 939:

(geology, now rare, archaic) Alternative letter-case form of vulcanian, volcanic, of or related to volcanoes and volcanism.

(historical) Of or related to former theories attributing the origin of basalt and other crystalline minerals to subterranean fires.

Just as we have the ‘Plinian’ or ‘Vesuvian’ eruptions of Vesuvius accompanied by violent outbursts of ‘ashes’ and welling out of lava, and the incessant, milder ‘Strombolian’ type of eruption, so we may distinguish a ‘Vulcanian’ type.

Of or related to volcanic eruptions or phases of a volcanic eruption when repeated explosions produce a thick ash cloud.

Solinus reports it of the Vulcanian Hill in Sicily, that they which offered Sacrifice upon it, never put fire to it, but expected it should be kindled from Heaven.

metamorphist

I am inclined to hold that there is a wide segment of truth embodied in the views of the metamorphists; but there seems to be also a segment of truth on the other side ; and so I must likewise hold with their antagonists, that there existed long periods in the history of the earth in which there obtained conditions of things entirely different from any which obtain now, —periods during which life, either animal or vegetable, could not have existed on our planet; and further, that the sedimentary rocks of this early age may have dreived, even in the forming, a constitution and texture which, in present circumstances, sedimentary rocks cannot receive.

1876, Hugh Miller, Sketch-book of Popular Geology, page 233:

A general laissez-faire sort of acceptance of the views of the more advanced metamorphists consoled some of us perhaps with the notion that it did not matter much whether tides had been greater agents of degradation of denudation and of transport in the remote ages of the Palaeozoic Period than in more recent times, since it was assumed that the oldest rocks we know were derived from other still older rocks.

1889, Kevin J. Donohoe, Annick Van den Abbeele, Teaching Atlas of Nuclear Medicine, page 73:

It has very properly been objected to the extreme views held by metamorphists that no kind of fusion or rearrangement of any kind is competent to metamorphose an ordinary greywacke into a granite, for the simple reason that the most important constituent of one of the essential minerals of the granite, to wit, the patash of the felspars, did not orignally occur in the material acted upon.

1894 January, J.G. Goodchild, “Augen-structure in Relation to the Origin of the Eruptive Rocks and Gneiss”, in Geological Magazine, volume 1, number 1, page 24:

In commenting on Mr. Ussher's views as they had been presented to the Society by his critic, Mr. Hudleston proceeded to say the Mr. Ussher was an ingenious metamorphist, who had evaded contradiction by assuming certain rocks not now existing to have been pre-Devonian, rocks obviously now beyond the disproof of chemical analysis.

1897, Transactions of the Devonshire Association for the Advancement of Science, Literature and Art, page 396:

As a metamorphist from the onset ( 1934-1935 ) I am afraid I might be partial.

1954, American Journal of Science and Arts, page 1954:

Thus started the war between magmatists and metamorphists which, like that classical one between plutonists and neptunists, degenerated sometimes to personal quarrels.

1957, International Union of Geodesy and Geophysics, Assemblée Générale - Volumes 11-13, page 50:

(historical, geology) A proponent of one side of an early geological controversy in the late 19th and early 20th century who held that differences between various nonsedimentary rocks and minerals could be explained by metamorphic processes rather than the opposing viewpoint that these differences resulted from cooling of different types of magma.


metamorphist

The deductions, in the works of Professor Keilhau, with which I have become acquainted since the publication of the first part of this work; the passages of the granite, which this geologist points out, to the stratified forms, considered together with the obscurity in which he confesses that the origin of the great mass of crystalline rocks is still involved, can only strengthen me in the opinion, that the theory of an igneous stratification of crystalline schists offers the only guide which can direct the geologist throught the labyrinth of difficulties with which a too limited interpretation of the general principle of stratification had encircled science, leaving it entirely to the speculations of the metamorphist geologists.

1847, Antoine Claude Gabriel Jobert, The Philosophy of Geology, page 108:

This strict identity of feldspars (and other crystals) has been for us, then for some other authors such as H.H. Read, a base for the metamorphist conception of the genesis of granites.

1953, Report of the Session - Volume 19, page 5554:

Such was still the case a few years ago when authors of a metamorphist tendency, such as Read (1943, 1944) still seemed to think that the intrusive appearance was consistent with a liquid intrusion only.

1954, American Journal of Science and Arts, page 450:

(historical, geology) Believing in the metamorphic formation of nonsedimentary rocks and minerals.

en-noun

Around Arabia - as well as in the Himalayas - these obductions completely obliterated the Neotethyan ocean, which in this time frame is represented only by a few exotic blocks and by Permo-Triassic pelagic sediments found at the sole of the Cretaceous ophiolites.

2004, Gérard M. Stampfli, Gilles D. Borel, “Chapter 3: The TRANSMED Transects in Space and Time”, in William Cavazza, François M. Roure, Wim Spakman, Gérard M. Stampfli, Peter A. Ziegler, editors, The TRANSMED Atlas: The Mediterranean Region from Crust to Mantle, Springer, page 73:

These frictional forces slowed the obduction of the ophiolite onto the continental margin and obduction ceased after the nappe was transported 100–200 km.

2011, Wolfgang Frisch, Martin Meschede, Ronald C. Blakey, Plate Tectonics: Continental Drift and Mountain Building, Springer, page 72:

Ongoing accretion at a subduction zone, and the obduction of intact ophiolite slabs, are not considered to be collision.

2012, Joseph A. DiPietro, Landscape Evolution in the United States, →ISBN, page 340:

(geology) The overthrusting of continental crust by oceanic crust or rocks from the mantle, such that the oceanic crust is thrust onto the continental crust, as occurs at a convergent plate boundary when the continental crust is caught in a subduction zone.
