Ore-bearing rocks were formed in the environment of passive continental margin, in unstable conditions, in the basin with strongly marked redox conditions. Systems of concordant thrusts and transverse faults, closely associated with them are the major ore-controlling structures. Several types of mineralization are manifested (from early to later ones): orogenic (metamorphogenic-hydrothermal, gold-quartz low-sulfide, gold-bismuth) and post-accretional (berthierite-antimonite and silver-antimony). Connection between mineral types of mineralization and stages of geodynamic development of the area is found. Key words: structural analysis, deformations, ore zones, mineral associations, mineralization stages, localization conditions, recycling, redox conditions, Triassic, East Р. 3-9 |

High-quality mortar, fast setting time, short waiting time on cement – the key to the successful construction of the well. However, as at any phase of well construction, mounting phase is accompanied by various complications. One such complication is the reduction in strength after cement hydration.
