MARBLE
recrystallised limestone for metamorphic action. If the original were impure limestones, in addition to calcite are also formed accessory minerals, especially calcium silicate. With increasing amounts of these minerals in the marbles pass calcefiri.
MELAFIRI
paleovulcaniche basaltic rocks, previous to the Tertiary age. The primary cavity of the rock are usually covered with quartz, chalcedony, chlorite and zeolites. The most recent similar rocks are basalts.
Metasco
schist, migmatite, and other metamorphic rocks that you do not recognize the original rock, embedded in metamorphic rocks derived from sedimentary rocks surely (Paraskevi) or eruptive (ortoscisti).
mica
generally quartz mica schists, Regional metamorphism of medium and high grade, derived from clay rocks, represent a more advanced degree of metamorphism of the phyllites, schistose texture are very clear. For the mineral characteristic stand with an adjective: garnetiferous mica, sillimanitici, amphibolites, graphite, etc..
migmatite rocks consist of a mixture of one part of metamorphic rocks and granite on one side or aplitica.
Milone
Rocks rnetamorfismo expatriation, having undergone deeper changes than those of cataclasiti. The composizione mineralogica è varia, dipendendo dalle rocce attraversate dalla zona di frattura in cui esse si formano.
MONZONITI
Rocce intrusive a struttura ipidiomorfa, caratterizzate da feldspato potassico e plagioclasio più o meno nella stessa quantità, da pirosseni, biotite e anfiboli.
NEFELINITI
Rocce filoniane e effusive laviche, ultrabasiche, prive di feldspati, con nefelina e augite.
NORITI
Gabbri a plagioclasi e pirosseno rombico predominanti: si distinguono inoltre noriti oliviniche con olivina; raramente le noriti non oliviniche possono contenere piccole quantità di quarzo (noriti quarzifere).
Ophiolites
Association of igneous and metamorphic rocks (diabase, Spilia, gabbro, serpentine, prasina, amphibolites) derived from basic magmas.

The quartz porphyry correspond to composition a rhyolite-daciti, quartz or non ortofiri to trachyte. Since the acid magma is viscous and their lavas do not expand easily, the vast expansion in quartz porphyry are interpreted as ignimbrites from the genetic point of view.

ROCKS _ A - B - C - D - E
When describing the minerals and speaks of their presence on Earth's surface, it is inevitable to mention the rocks in which they are found. Since this blog is dedicated exclusively to the minerals, I thought it appropriate to create a short dictionary of the rocks above. It is not a complete dictionary, but includes the most common rocks and it is sufficient to guide the reader of these pages in the complex world of petrography, which is the science that studies the rocks, their origin and their composition.
ALABASTER
Limestone (calcareous alabaster) or gypsum (alabaster gypsum) of chemical deposition in caves, sometimes on the surface, listings, for the most colorful areas in vanishing, typically translucent. The stalactites and other concretions of limestone caves are generally made of alabaster.
ANDES

amphibole
green rock consisting essentially of regional metamorphism of amphibole and plagioclase. They differ different types of amphibolites adding the adjective of the mineral characteristic: epidote amphibolite, biotitic, etc. granatifere.
anorthosite
Intrusive rocks consist almost entirely of calcic plagioclase with small amounts of minerals femici (pyroxene and amphibole).
APLITI
intrusive and metamorphic rocks rich in silica (ipersiliciche), with abundant quartz and feldspar, less or no mineral femici. Generally constitute the bulk of the granitic migmatite or differentiation of acid magma in different compositions, or the filling of veins, veins and apophyses; grain have very minute.
SANDSTONE

BASALT
blackish effusive rocks consist of calcic plagioclase, pyroxene, olivine, sometimes with amphiboles, the structure is often microcrystalline, rarely porphyritic with phenocrysts of plagioclase, pyroxene, olivine.

sediments and sedimentary rocks composed predominantly of calcium carbonate (CaC03). Similar rocks, are completely recrystallised metamorphic environment in these marbles. We consider pure limestones that contain at least 95% of CaC03, impure or mixed ones containing less, up to 50%.
CALCEFIRI
contact metamorphic rocks derived from marly limestone or acidic, limestone is also recrystallized. The calcefiri are rich in silicates calciferous and sometimes of rare minerals.
schists
shale produced by intense metamorphism non Sediment predominantly limestone or marl. The calcite, recrystallized, alternate with beds of mica and other silicates. For the formation of schists is the presence of pressure-oriented a determining factor.
CARBONATE
Rocks with predominantly calcite, with magnetite, Mg minerals, micas, apatite and other minerals found in veins, associated with alkaline igneous rocks. Their origin is debated and difficult to explain: they are considered intrusive rocks formed by consolidation of magma hypothetical carbonate, or limestone metamorphosed sedimentary or limestone dissolved in streams and rideposti from hydrothermal solutions.
CHERATOFIRI
extrusive igneous rocks acidic or neutral or filoniane, spilitizzate (enriched, ie, minerals sodium) containing albite or sodic plagioclase, chlorite, calcite and epidotes, and the varieties that contain cheratofiri quartz crystal are called.

CORNUBIANITI
metamorphic rocks derived from sedimentary rocks, generally clastic, to intense thermal metamorphism. The structure is granoblastica; between the components are: quartz, feldspar, garnet, cordierite, andalusite, and other silicates epidotes The cornubianiti are tough, compact, fine grain, are formed in the inner part of dell'aureola contact.
DACITI
neutral effusive rocks, lava, tuff and ignimbrite often, Orphic structure, with phenocrysts of quartz, plagioclase, biotite, amphibole or pyroxene may, with the bottom dough microcrystalline or glassy. Chemical composition may be the granodiorite. Formed from magmas of the province peaceful.
Diabas

When there are phenocrysts of the rock called diabase porphyrias. They are also called diabase rocks and submarine effusion subvulcanica basic, spilitiche (ore-sodium).
DIOR
neutral intrusive rocks with a predominance of plagioclase and pyroxene, amphibole and / or biotite. The structure is almost always granular olocristallina. Rocks are widespread and normally associated with granodiorite and granite.
DOLOMITE
rocks consist mainly of dolomite. There are all intermediate steps between limestone and dolomite.
Eclogite
metamorphic rocks with pyroxene and garnet, sometimes associated with other minerals such as amphiboles, which bear witness to the phenomena of retrometamorfismo (transition from metamorphism metamorphism intense light). They have different colors, more often green-red, and high density.
ECTINITI
regional metamorphic rocks of metasomatic not, that is, with no or with minor changes from the original chemical composition of the rock.
ESSEX
alkaline intrusive rocks, rare, characterized by the association of plagioclase, amphibole and sodic pyroxene, nepheline and alkali feldspar.
EUFOTIDE
Gabbro to coarse plagioclase and pyroxene (diallagio), widespread in the Apennines.
STEAMED
chemical sedimentary rock consisting of precipitated salts for supersaturation of the waters in which they were dissolved, by evaporation. Carbonates, sulfates, chlorides of Ca, Mg, Na, K are its constituents.

sediments and sedimentary rocks composed predominantly of calcium carbonate (CaC03). Similar rocks, are completely recrystallised metamorphic environment in these marbles. We consider pure limestones that contain at least 95% of CaC03, impure or mixed ones containing less, up to 50%.
CALCEFIRI
contact metamorphic rocks derived from marly limestone or acidic, limestone is also recrystallized. The calcefiri are rich in silicates calciferous and sometimes of rare minerals.
schists
shale produced by intense metamorphism non Sediment predominantly limestone or marl. The calcite, recrystallized, alternate with beds of mica and other silicates. For the formation of schists is the presence of pressure-oriented a determining factor.
CARBONATE
Rocks with predominantly calcite, with magnetite, Mg minerals, micas, apatite and other minerals found in veins, associated with alkaline igneous rocks. Their origin is debated and difficult to explain: they are considered intrusive rocks formed by consolidation of magma hypothetical carbonate, or limestone metamorphosed sedimentary or limestone dissolved in streams and rideposti from hydrothermal solutions.
CHERATOFIRI
extrusive igneous rocks acidic or neutral or filoniane, spilitizzate (enriched, ie, minerals sodium) containing albite or sodic plagioclase, chlorite, calcite and epidotes, and the varieties that contain cheratofiri quartz crystal are called.
CLORITOSCISTI
metamorphic rock mainly chlorite, sometimes with talc and various carbonates, derived from basic and ultrabasic igneous rocks, formed by low-grade metamorphism.
CORNUBIANITI
metamorphic rocks derived from sedimentary rocks, generally clastic, to intense thermal metamorphism. The structure is granoblastica; between the components are: quartz, feldspar, garnet, cordierite, andalusite, and other silicates epidotes The cornubianiti are tough, compact, fine grain, are formed in the inner part of dell'aureola contact.
DACITI
neutral effusive rocks, lava, tuff and ignimbrite often, Orphic structure, with phenocrysts of quartz, plagioclase, biotite, amphibole or pyroxene may, with the bottom dough microcrystalline or glassy. Chemical composition may be the granodiorite. Formed from magmas of the province peaceful.
Diabas
basic igneous rocks with similar composition to that of gabbros and basalts, subvulcaniche often filoniane, Ophites structure, with abundant calcic plagioclase, pyroxene, olivine rarely. When there are phenocrysts of the rock called diabase porphyrias. They are also called diabase rocks and submarine effusion subvulcanica basic, spilitiche (ore-sodium).
DIOR
neutral intrusive rocks with a predominance of plagioclase and pyroxene, amphibole and / or biotite. The structure is almost always granular olocristallina. Rocks are widespread and normally associated with granodiorite and granite.
DOLOMITE
rocks consist mainly of dolomite. There are all intermediate steps between limestone and dolomite.
Eclogite
metamorphic rocks with pyroxene and garnet, sometimes associated with other minerals such as amphiboles, which bear witness to the phenomena of retrometamorfismo (transition from metamorphism metamorphism intense light). They have different colors, more often green-red, and high density.
ECTINITI
regional metamorphic rocks of metasomatic not, that is, with no or with minor changes from the original chemical composition of the rock.
ESSEX
alkaline intrusive rocks, rare, characterized by the association of plagioclase, amphibole and sodic pyroxene, nepheline and alkali feldspar.
EUFOTIDE
Gabbro to coarse plagioclase and pyroxene (diallagio), widespread in the Apennines.
STEAMED
chemical sedimentary rock consisting of precipitated salts for supersaturation of the waters in which they were dissolved, by evaporation. Carbonates, sulfates, chlorides of Ca, Mg, Na, K are its constituents.
