For
the purposes of this European Standard the following abbreviations apply:e.g.
for example (Latin exempli gratia);i.e.
that is (Latin id est).2.1 Geological terms2.1.1 accessory minerals: Rock-forming minerals that occur in such small amounts that they arenot included in the classification of the rock.NOTE
Accessory minerals can be used to state precisely the name of the rock, e.g. biotite granite. (See also EN12440).2.1.2 acid rock: Igneous rock that contains more than 65 % of silica.2.1.3 actinolite: Ca-Mg-Fe-amphibole. See amphibole formula.2.1.4 agate: Cryptocrystalline variety of silica, showing a variegated banded structure and waxyluster.2.1.5 agglomerate: Extrusive pyroclastic rock of consolidated or unconsolidated coarse volcanicfragments (with diameters greater than 64 mm), in which rounded pyroclasts predominate.2.1.6 alabaster: Fine grained, compact variety of gypsum, usually white or pale coloured andtranslucent.2.1.7 albite: Sodium plagioclase, formula Na Al Si3 O8 See plagioclase.2.1.8 alkali feldspar: The alkali-rich feldspars microcline, orthoclase, sanidine, albite, with less than5% anorthite. See feldspar and plagioclase.2.1.9 allochems: One of the several varieties of discrete and organized carbonate aggregates thatserve as the coarser framework grains in most mechanically deposited limestones. Importantallochems include: silt, sand, gravelsize intraclasts ooids; pellets; lumps and fossils or fossilfragments.2.1.10 allotriomorphic; anhedral; xenomorphic:
Term applied to minerals which show in thinsections no characteristic or rational faces, suggested by its crystalline structure.2.1.11 alteration: Changes of the mineralogical composition of a rock brought about by physical,chemical or biological means, including actions of hydrothermal solutions and weatheringprocesses. Differs from metamorphism in being milder, more localized and not restricted tohigh temperatures.2.1.12 alumina; corundum: A mineral, formula Al2O3. Used in fine polishing.2.1.13 amorphous: Mineral that does not have a crystalline structure.2.1.14 amphibole: Family of dark ferromagnesian silicate minerals, general formulaA2-3B5(Si,Al)8O22(OH)2, where A= Mg, Fe2+, Ca, Na; B=Mg, Fe2+, Fe3+, Al.2.1.15 amphibolite: Metamorphic rock consisting mainly of amphibole and plagioclase. See 3.2.3.12.1.16 amygdaloidal: Fabric of volcanic rocks where vesicles are present, which are full or partiallyfilled with secondary minerals.2.1.17 analcime: A mineral Na AlSi2O6 H2O of the zeolite group, which can occur in basalts. SeeSIST EN 12670:2002
mainly composed of sand-size detrital fragments ormineral grains, usually the term is used with a prefix that refers to its composition or genesis,e.g. quartzarenite. See also 3.2.2.42.1.32 argillite: Consolidated sedimentary rock mainly composed wholly of detrital clay-size particlesor clay minerals.2.1.33 arkose: Sedimentary detrital rock with less than 75 % quartz and a high content of feldspargrains. See 3.2.2.4.2.1.34 augen fabric; ocellar fabric: Fabric in some rocks, usually metamorphic, consisting ofellipsoidal or lens-shaped porphyroblasts, crystals, or fragments, rounded and enveloped bythe foliation, resembling eyes (augen) in a cross section.2.1.35 augite (clinopyroxenes): Mineral of the pyroxene group (clinopiroxenes), general formula(Ca,Na) (Mg,Fe2+,Al) (Si,Al) 2O62.1.36 banded: Rock having alternating nearly parallel layers that differ in colour, fabric or mineralcomposition, and because of that it shows alternating bands in a cross section.2.1.37 basalt (basanite): a) Scientifically: volcanic rock consisting essentially of plagioclase (labradorite-anorthite) andpyroxene and includes a fine grained to dense fabric (See 3.2.1.3). b) Commercially: basalt is a natural stone as per the scientific definition of basalt and other rockssuch as basalt, picrites, diabases, dolerites and microgabbros.2.1.38 basic: Igneous rock with more than 45 % and less than 52 % of silice.2.1.39 bedding plane: a) A planar or nearly planar surface that visibly separates the individual beds, layers or strata,especially in sedimentary rocks.SIST EN 12670:2002
