In the Geology/Earth Sciences literature, carbonatites are accepted as rocks of magmatic origin that are rarely seen in nature as intrusions, carbonatite dykes, veins, pegmatitics, stocks, sills and lenses. The view that carbonatites are of magmatic origin and rarely seen in nature is definitely not true. On the contrary Carbonatites are rootless, metamorphic origin, a new type of modern metamorphic rocks, pure-impure leucocratoblastic (light colored, rock composed of different carbonate origin/based crystalloblast neominerals) carbonatoblastic rocks / carbonatoblastites / carbonatoblastic rock series and their derivatives. Pure-impure leucocratoblastic carbonatoblastic rocks / carbonatoblastites, whose primary source rocks are different (pure-impure carbonate/limestone) They form a type of leucocratoblastic metablastic rocks, which are of metamorphic origin, rootless, a type of new modern metamorphic rocks, with a granite mineralogical composition and composed of silicate origin/based crystalloblast neominerals. Carbonatoblastic rocks (known as carbonatites, rarely seen in nature, which are of magmatic origin until today) They developed in the last/second closing stage of the regional dynamothermal Tarhan metamorphism cycle, and they developed in the changing physical conditions (P/T) of the facies and sub-facies of Abukuma type reversed regional regressive dynamothermal metamorphism, where temperatures are effective in proportion to/compared to pressures (T>P, P, Pressure T, Temperature Temperatures put their stamp on the metamorphism). Previously existing primary source rock units pure-impure carbonate/limestones They developed in the first initial phase of the regional dynamothermal Tarhan metamorphism cycle, within pure and impure classical marbles, which are the metamorphic equivalents of Barrow type regional progressive dynamothermal metamorphism, where pressures are effective compared to/in proportion to temperatures (P>T, pressures put their stamp/mark on the metamorphism). Carbonatoblastic rocks/carbonatoblastites were derived in solid phase and in-situ (autochthonous) from the pure-impure classical marbles in the Abukuma type inverted regional regressive dynamothermal metamorphism type/phase that developed in the second/last closing phase of the metamorphism cycle. Metamorphic origin leucocratoblastic pure-impure carbonatoblastic rocks derived from pure-impure carbonate/limestones of different primary rocks They constitute a new type of modern metamorphic rocks of metamorphic origin, rootless, leucocratoblastic metablastites / metablastic rocks / metablastic rock series and their derivatives, defined for the first time under the general name, named and different types. Pure-impure carbonatoblastic rocks / carbonatoblastites / carbonatoblastic rock series and derivatives under the name of many carbonatoblastite type metablastic rocks (alkali metablastites, syenitoblastite, monzonitoblastite, calcitoblastite, calcito-dolomitoblastite, dolomitoblastite, sideritoblastite, stroncianitoblastite etc.) and carbonate origin / based rock forming main-secondary-trace crystalloblast neominerals (calcitoblast, dolomitoblast, witheritoblast, stroncianitoblast etc.) etymologically redefined for the first time, named, classified, physical-chemical properties determined. Carbonatoblastic rocks / Carbonatoblastites / Carbonatoblastic rock series and their derivatives It has been determined for the first time that they have very rich and widespread potential in terms of metablastic ore/mine deposits of metamorphic origin, defined and named for the first time. Different carbonatoblastic rock types develop depending on the composition and contents of pure-impure carbonate/limestones, which are pre-existing primary origin rock units. In the changing physical conditions (P/T) of the facies and sub-facies of the Abukuma type reversed regional regressive dynamothermal metamorphism, which developed in the last/second/closing phase of the regional dynamothermal Tarhan metamorphism cycle, where temperatures are effective compared to pressures (T>P, temperatures put their stamp on the metamorphism), protominerals (minerals of primary source rocks) - metaprotominerals (classical metamorphic minerals of metamorphic equivalent rocks of primary source rocks) lose their stability and are partially and completely gradually dissolved in the solid phase and in-situ. With dissolution in the solid phase solid neo-solutions with different chemical compositions, anhydrous, unstable and disordered structures, consisting of free and unstable ions (cation, anion) of different elements with increased electrically charged and atomic diffusion rates are widely developed. In the current physicochemical conditions of the facies and subfacies of the abukuma type inverted regional regressive dynamothermal metamorphism, recrystallization by metablastization commonly develops from unstable solid neo-solutions with different chemical compositions due to the temperatures effective in the environment. With the recrystallization developing by metablastation from solid neo-solutions rock-forming main-secondary-trace element cations, metallic-non-metallic ore cations, radioactive and rare earth elements/REE, which are incompatible elements with large ionic radii, are electrically charged, have increased atomic diffusion rates, and are free and unstable cations They combine with root carbonate anion (CO3)2-, root silicate anion (smooth surface silicon tetrahedral) (SiO4)4- / or [(Si, Al)O4]4- and oxygen (O2-) anions (due to polarization, solid-solid chemical reactions) and develop free blast/embryo/nucleus/bud and blast/embryo aggregates of their own unique/belonging minerals. In this way, the ions become electrically neutral and become stable. Blast/embryo, blast/embryo aggregates with the same and similar geochemical properties formed in the current/setting physicochemical conditions of Abukuma type reversed regional regressive dynamo-thermal metamorphism where temperatures are effective compared to pressures (T>P, temperatures put their stamp on the metamorphism) group among themselves and add to each other, and gradually grow as crystalloblast, porphyroblast and megacrystalloblast type rock-forming main-secondary-trace, metallic-non-metallic ore-forming, strategic, radioactive and light-heavy rare earth elements/REE free/independent crystalloblast neominerals. In this way, metallic-non-metallic ore crystalloblast neominerals, strategic crystalloblast neominerals, radioactive-rare earth elements/REE from incompatible elements with large ionic radii that cannot easily enter the crystal structures of rock-forming main-secondary-trace crystalloblast neominerals are naturally produced by their own crystalloblast neominerals. They become enriched and visible in the environment/setting. They are naturally enriched and become visible in the form of crystalloblast neominerals in leucocratoblastic carbonatoblastic rocks, which are rootless and a type of new modern metamorphic rocks of metamorphic origin. It has been determined and suggested for the first time that they develop the richest metamorphic-origin metablastic ore/mine deposits in the world by growing freely in the form of metallic-non-metallic crystalloblast neominerals that are unique/belonging to them. Carbonatoblastic rocks / Carbonatoblastites / Carbonatoblastic rock series and their derivatives are also very rich in terms of their contents of precious and semi-precious stones, ornamental stones (Gemology) and natural colored-patterned building stones (natural ceramic stones). Carbonatoblastic rocks They form the 2nd generation metamorphic rocks, the 3rd generation rocks, allotropic superionic metablastic matter / mine / rock / minerals and the 5th classical state of matter. All these geological phenomena appear before us as the products of the metamorphic view that constitutes the regional dynamo-thermal Tarhan metamorphism cycle that has been determined and suggested for the first time. They are not the products of the magmatic view. They are not the products of logical imagination models either. Therefore, if material, moral and temporal losses are not desired for scientific studies on similar topics, but reversible economic gains are desired, the magmatic view should be rejected. In contrast, the metamorphic view should be accepted.
