MINERAL TRANSFORMATIONS OF HYALOCLASTITE DURING LITHOGENESIS IN MASSIVE SULFIDE BEARING REGIONS OF URALS [PDF]

Минералогия, 2015
The features of the submarine transformations from primary hyaloclastites to oxide-ferruginous rocks of the Urals massive sulfide deposits are identified. These processes are accompanied by formation of smectite and Si-Fe phases transformed into chlorite-

Insights into secondary reactions occurring during atmospheric ablation of micrometeoroids [PDF]

, 2016
Ablation of micrometeoroids during atmospheric entry yields volatile gases such as water, carbon dioxide, and sulfur dioxide, capable of altering atmospheric chemistry and hence the climate and habitability of the planetary surface.

NEW DATA ON PYROCHLORE OF ALKALI PEGMATITES AND ORE ZONES OF THE VISHNEVYE MOUNTAINS (SOUTHERN URALS) [PDF]

Минералогия, 2018
The minerals of the pyrochlore group are abundant in rocks of the Vishnevogorsk alkaline complex – miaskites, mica rocks, carbonatites, and their pegmatites. Several generations of pyrochlore can be found in complex pegmatite bodies.

Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

Deep Underground Science and Engineering, EarlyView.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring
