PECULIARITIES OF THE MINERAL COMPOSITION AND ORIGIN OF THE SIILLINJARVI CARBONATITES (FINLAND)
Keywords:
carbonatite, igneous silicate rocks, apatite, tetraferriphlogopite, petrogenesis, isotopes of C, O, Sr, Siilinjarvi, Finland.Abstract
The article presents the results of investigations of the Precambrian carbonatites (alvikites and beforcites) from the Siillinjarvi deposit (Finland). The carbonatites intruded into the older phlogopite-bearing rocks – syenites and glimmerytes. Dolomite and calcite are the main minerals of the carbonatites (more than 70 % of the total carbonatite volume). Apatite, tetraferriphlogopite and richterite are the secondary minerals. The accessory minerals are presented by strontianite, monazite, pyrochlore, baddeleyite, ilmenite, magnetite and pyrite. We established the stable chemical composition of the phlogopite. Take into consideration carbonates homogeneity and absence of their secondary phases we estimated crystallization temperature about 540 °С (according to the Talantsev’s thermometer), and it is close to crystallization temperature of the coexisting carbonates according to isotopic calculations. Apatite of the deposit is rich in strontium and considerable variations of the strontium isotopes are characteristic. Isotopic composition of carbon and hydrogen from the Siillinjarvi carbonates are also variable, and often are not similar to the typical for young carbonatites.
