[to sway, move backward and forward] Middle English rokken "rock (a cradle), cause to sway back and forth; rock (someone) in a cradle," from late Old English roccian "move a child gently to and fro" in a cradle, which is related to Old Norse rykkja "to pull, tear, move," Swedish rycka "to pull, pluck," Middle Dutch rucken, Old High German rucchan, German rücken "to move jerkily." The intransitive sense of "move or sway back and forth unstably" is from late 14c. For the popular music senses, see rock (v.2). Related: Rocked; rocking. The earliest associations of the word were with slumber, rest, security. The sense of of "sway to and fro under some impact or stress" is from late 14c., especially of vessels in the waves (1510s); hence rock the boat in the figurative sense "stir up trouble" (1914). The sense of "swing to and fro in or as in a rocking chair" is by 1795.

1776, originally of land, "having rocky rib-like ridges;" figurative sense of "resolute" is recorded by 1887; see rock (n.) + rib (n.).

There are 2 QAPF diagrams, one for coarse grained (plutonic) or intrusive igneous rocks, one for fine grained (volcanic) or extrusive igneous rocks. Hello all, It's been a few years since I have graduated with my Geology degree, and I have stumbled upon a rock that confuses me. I am now working at Acadia National Park, which is mostly composed of a series of different granites. Within some of these granites are intruding dikes of "Diabase". When I googled "Diabase", I am told that it is a black fine grained intrusive igneous rock. As far as minerals go, it is mostly comprised of types of plagioclase and types of pyroxenes.

Sep 24, 2021 · A template for ternary plots (Excel 45kB Nov17 09) using Excel from Yaoling Niu, Professor of Earth Sciences, Department of Earth Sciences, Durham University. Igneous AFM diagram is demonstrated, but the ternary components can be readily modified to … Peridotite is a dark-colored igneous rock consisting mostly of olivine and pyroxene. It is an important rock type because the Earth’s mantle is predominantly composed of it. A classification diagram of ultramafic rocks. Note that neither peridotite nor pyroxenite are single rock types. They are further divided into subtypes. Feb 24, 2019 · The QAP ternary diagram is used to classify igneous rocks with visible mineral grains (phaneritic texture) from their feldspar and quartz content. In plutonic rocks , all of the minerals are crystallized into visible grains.

Accommodating feldspar on Streckeisen ternary diagrams · by C Stanley · 2017 · Cited by 3 — Lithogeochemical classification of igneous rocks using Streckeisen ternary diagrams. Cliff Stanley. Sometimes extrusive igneous rocks cool so quickly that no crystals form. This is especially likely to happen if lava meets water. The result is a rock composed of volcanic glass called obsidian.Examples of obsidian appeared in Figures 1.21 (Chapter 1) and Figure 4.5 (Chapter 4). In other cases, different minerals may grow to distinctly different sizes. So for context I am a geologist learning how to create a IUGS Plutonic Rock Diagram, Volcanic Diagram , and eventually a QAPF Diagram for ggplot2. Like everything in life, its best to learn how to walk before one learns to run, right? With that in mind I decided to modify [this chart](http://www.ggtern.com/2014/07/26/user-request-shepards-classification-sediments/) to be more inline with a [IUGS Plutonic Diagram](https://www.thoughtco.com/igneous-rock-classification-diagrams-4122900).

A novel alternative procedure for igneous rock classification involves using whole rock lithogeochemical data for classification on Streckeisen ternary diagrams ... 1660s, "pertaining to or resembling fire," from Latin igneus "of fire, fiery; on fire; burning hot," figuratively "ardent, vehement," from ignis "fire, a fire," extended to "brightness, splendor, glow;" figuratively "rage, fury, passion," from PIE root *egni- "fire" (source also of Sanskrit agnih "fire, sacrificial fire," Old Church Slavonic ogni, Lithuanian ugnis "fire"). Geological meaning "produced by volcanic forces" is from 1791, originally in distinction from aqueous. Earlier in the sense "fiery" were ignean (1630s), ignic (1610s). Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic.Igneous rock is formed through the cooling and solidification of magma or lava.. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.Typically, the melting is caused by one or more of ... What is Feldspar? Feldspar is the name of a large group of rock-forming silicate minerals that make up over 50% of Earth's crust. [1] They are found in igneous, metamorphic, and sedimentary rocks in all parts of the world. Feldspar minerals have very similar structures, chemical compositions, and physical properties. Common feldspars include orthoclase (KAlSi 3 O 8), albite (NaAlSi 3 O 8), and ...

1610s, "an illustrative figure giving only the outlines or general scheme of the object;" 1640s in geometry, "a drawing for the purpose of demonstrating the properties of a figure;" from French diagramme, from Latin diagramma "a scale, a musical scale," from Greek diagramma "geometric figure, that which is marked out by lines," from diagraphein "mark out by lines, delineate," from dia "across, through" (see dia-) + graphein "write, mark, draw" (see -graphy). Related: Diagrammatic; diagrammatically. The verb, "to draw or put in the form of a diagram," is by 1822, from the noun. Related: Diagrammed; diagramming.

"to dance to popular music with a strong beat," 1948 (in song title "We're gonna rock"), from rock (v.1) in an earlier blues slang sense of "cause to move with musical rhythm" (1922); often used at first with sexual overtones, as in the 1922 song title "My Man Rocks Me (with One Steady Roll)". The sense developed in early 1950s to "play or dance to rock and roll music." Also see rock (n.2). Related: Rocked; rocking. In reference to music, by 1938 as "to have a rocking rhythm;" by 1977 as "exhibit the characteristics of rock music." To rock out "enjoy oneself to rock music" is by 1968. Rocksteady, Jamaican pop music style (precursor of reggae), is attested from 1969.

"threefold," early 15c., from Late Latin ternarius "consisting of three," from terni "three by three," from ter "thrice," which is related to tres "three" (see three).

1823, "action of rocking; a movement to and fro," from rock (v.1). As short for rock and roll, by 1957; but the sense of "musical rhythm characterized by a strong beat" is from 1946, in blues slang (Mezz Mezzrow, "Really the Blues"). Rock star is attested by 1966.

[stone, mass of mineral matter], Middle English rokke, roche "stone as a substance; large rocky formation, rocky height or outcrop, crag," from Old English rocc (as in stanrocc "stone rock or obelisk") and directly from Old North French roque, variant of Old French roche, which is cognate with Medieval Latin rocca (8c.), from Vulgar Latin *rocca, a word of uncertain origin. According to Klein and Century Dictionary, sometimes said to be from Celtic (compare Breton roch). Diez suggests Vulgar Latin *rupica, from Latin rupes "rocks." In Middle English it seems to have been used principally for large rock formations but occasionally of individual boulders. The extended sense of "a stone of any size" is by 1793, American English colloquial, and long was considered incorrect. It is an error to use rock for a stone so small that a man can handle it : only a fabulous person or a demi-god can lift a rock. [Century Dictionary] The meaning "precious stone," especially a diamond, is by 1908, U.S. slang; the sense of "cr

1918 (Venn's diagram is from 1904), named for English logician John Venn (1834-1923) of Cambridge, who explained them in the book "Symbolic Logic" (1881).

phrase in nursery rhyme sleeping-songs, by 1805; see rock (v.1). Compare lullaby.

Jun 03, 2019 · Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains.

A QAPF diagram is a double ternary diagram which is used to classify igneous rocks based on mineralogic composition. The acronym QAPF stands for "Quartz, Alkali feldspar, Plagioclase, Feldspathoid (Foid)". These are the mineral groups used for classification in QAPF diagram. Q, A, P and F percentages are normalized (recalculated so that their sum is 100%).

Igneous rocks are fashioned deep internal Earth's crust (intrusive rocks) or on the floor (extrusive rocks). As molten rock (called magma) below the surface cools, the liquid cloth starts to solidify into minerals of differing sizes and compositions.
