Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Forecast of tectonic disturbances zones in coal layers
Geofizicheskiy Zhurnal, 2023 У статті розглянуто проблему виділення поширених геологічних порушень у гірських породах. Мета дослідження — апробація методики виявлення тектонічних порушень і їх геометричних параметрів у вугільних пластах. Наведено результати аналізу накопиченої інформації, що стосуються вивчення мікроструктури вугілля — квазікристалів, яка є наслідком тектонічних ...
