Abstract - Summary
(short description): | |
In the result of mineralogical “pasportization” of kimberlite pipes from the different fields of Yakutian province we received a numerous data (more 10000 analysis) of chemical composition of indicator minerals of kimberlites (magnesium ilmenite, garnet and chrome spinel). The generalization of these data has practical and scientific significance. Next genetic conclusions were done about origin of indicator minerals: 1) the crystallization of macrocrysts of magnesium ilmenite and chrome spinel was connected with formation of kimberlites; 2) there is opportunity of the using of ilmenite for the deciphering of structure of kimberlite fields (that is important for elaboration of model of field formation). Analysis of tremendous volume of data on the garnet composition gives opportunity of modeling of profiles of lithosphere mantle under each studied kimberlite field. The separate metasomatised blocks of lithosphere mantle were distinguished on the high content of TiO2 in the garnets.
The mineralogical pasportization extended (improved) opportunities of the using of prospecting methods of discovery of new kimberlite pipes. The conclusions about the thorough source of any secondary halo of ilmenite it’s necessary to do by means of comparison of plots MgO- Cr2Î3 for Ilm from halo and nearest famous kimberlite pipes. |
