Floor marble (marble) of the amankutansky field
QUALITATIVE CHARACTERISTIC
MRAMORIZOVANNY LIMESTONES AND MARBLE
FIELD OF AMANKUTAN UCH. KYZYLBASH
The site Kyzyl-bash a pit Anniversary, is located in 50 km to the south from Samarkand.
The field is put by the marbleized limestones of white, pale gray, pinkish-gray coloring.
Mramorizovanny limestones under microscopes consist of grains of calcite of 0.25 in size - 0.5mm, is more rare 1±5мм izometrichno-extended, sometimes than irregular shape. Calcite recrystallization is accurately observed. Structure of mramorizovanny limestones from small - to coarse-grained.
On quality indicators mramorizovanny limestone and marble correspond to GOST 22356 on crushed stone and sand decorative of a natural stone for external and internal facing on cement mortar and TSh 64-03883365 on a rubble stone for production of calcite of marble powder.

Radioactivity of breeds productive thicknesses of-1-5 μR/hour.
Data of researches on a radiation and hygienic assessment showed that the marbleized limestones and marble on the total content of radionuclides belong to 1 class that allows to use them in constructions without restrictions.
