Origin and Formation of Carbonatoblastites (Known as Carbonatites); The First Prototype Constitution of the Article
Year: 2024
Type: article
Abstract: To date, carbonatites are known as rocks of magmatic origin, rare in nature. However, as a result of our scientific research (field, petrographic and mineralogical studies, etc.), it has been determined that carbonatites are not of magmatic origin. Carbonatoblastites (known as carbonatites of magmatic origin and rarely seen in nature); developed within the regional dynamothermal Tarhan metamorphism cycle, and developed in the changing physical conditions (P/T) of the facies and sub-facies of the Abukuma type reversed regional regressive dynamothermal metamorphism, where temperatures are effective compared to pressures (T>P, temperatures have left their mark/seal on the metamorphism). Pure-impure carbonate/limestones, which are primary rock units, and pure-impure marbles, which are the metamorphic equivalent rocks of Barrow-type regionally progressive dynamothermal metamorphism, where pressures are effective compared to temperatures of primary rock units (P/T, pressures have left their mark on metamorphism), they were formed within. Carbonatoblastites are derived in the solid phase and in-situ from the rock units in which they were formed. Carbonatoblastites/Carbonatoblastic rock series and their derivatives are defined, named and classified under the general name of modern metablastic rock series and their derivatives, which are a new type of metamorphic rocks of metamorphic origin, rootless, of pure-impure carbonate/limestones with different primary rocks. Metablastic rock series and their derivatives are formed from different primary source rock units. Under the name of carbonatoblastites/carbonatoblastic rock series and their derivatives, many different carbonatoblastite type metablastic rocks (alkali metablastites, syenitoblastite, monzonitoblastite, calcitoblastite, calcito-dolomitoblastite, dolomitoblastite, sideritoblastite, stroncianitoblastite etc.) and carbonate-based rock-forming main-secondary-trace carbonatoblast type different crystalloblast neominerals (calcitoblast, dolomitoblast, witheritoblast, stroncianitoblast etc.) have been etymologically redefined, named, classified and their physical-chemical properties have been determined. Carbonatoblastic rock series and their derivatives/carbonatoblastites (known as carbonatites of magmatic origin and rare), contrary to the views in Geology/Earth Sciences literature that they are rarely seen in nature, have very thick and widespread outcrops within the metamorphic belts on our planet, the Earth. They were generally defined and mapped as recrystallized limestone/carbonate and marbles by previous researchers.
