Neotectonics and geodynamics of the Kuznetsk Basin

Geoecological aspects of stress-strain state modeling results of Leninsky coal deposit (Kuzbass, Russia)

“…The fault in the model corresponds to mechanically dispersed environment with the width of the fracture zone up to 500 m [Morozov et al, 2012]. The dip of fault was assumed as vertical at interval depth of intensive mining works.The external field of tectonic stresses is specified by the dominant compression stress with the submeridional orientation axis, which is consistent with the materials of morphotectonic [ Novikov et al, 2013;Panina and Zaitsev, 2012] and seismological [Emanov, 2009;Ovsyuchenko et al, 2010;Zhalkovsky et al, 1995] research.…”

“…Against the background of Altai-Sayan folded region, represents a set of mountain ranges, clearly expressed in relief in the form of mountain ranges [Nedra, 1967]. Modern geodynamic activity is expressed in the growth of new elevations due to the reduction of depressions resulted from the general uplift of the territory [Panina and Zaitsev, 2012]. This is confirmed by geo-morphological data, by the results of re-leveling, by observations using global navigation satellite systems (GNSS), as well as by spontaneous gas emission in the territory of the Leninsky coal deposit (LCD) [Batugina and Petukhov, 1988;Kartashev and Yesikov, 1983;Novikov et al, 2013;Panina and Zaitsev, 2012].…”

“…A large amount of geological, tectonic and seismological data about the state of this area has been accumulated over the long period of LCD operation [Adushkin, 2015;Emanov, 2009;Lazarevich and Polyakov, 2009;Novikov et al, 2013;Panina and Zaitsev, 2012;Yakovlev et al, 2013]. Large-scale mining operations cause massive anthropogenic changes in the geological environment, which lead to a negative impact on the geological environment, water objects, the ground surface and the biosphere.…”

“…To determine the tectonic component of stresses, we used the data on the direction of the axes of the main tectonic stresses. The data was based on the results of morphotectonic studies of the Kuznetsk basin [Novikov et al, 2013;Panina and Zaitsev, 2012]. The modeling of the stress-strain state of LCD is made using the calculation method of stress-strain state of heterogeneous block arrays with system of tectonic faults.…”

Deep structure of the Salair fold-nappe terrane (NW CAOB) according to magnetotelluric sounding

“…1). В тектонической истории Салаира выделяется несколько орогенических событий: 1) раннеордовикская аккреция островодужных комплексов к Сибирскому континенту, вызвавшая складчатость кембрийско-раннеордовикского фундамента [Berzin et al, 1994, Berzin, Kungurtsev, 1996Metelkin, 2012]; 2) позднепермский орогенез, связанный с закрытием Палеоазиатского океана и явившийся причиной формирования гранитоидных интрузий и складчато-покровной структуры Салаира [Zonenshain et al, 1990]; 3) мезозойский орогенез, проявившийся в накоплении грубообломочных отложений сопряженных с Салаиром грабен-синклиналей и реактивации позднепалеозойских надвигов [Vdovin, 1976;Novikov et al, 2019], и, наконец, 4) позднекайнозойская активизация, свидетельством которой служит неотектоническое поднятие Салаирского кряжа [Novikov et al, 2008b[Novikov et al, , 2013[Novikov et al, , 2019Novikov, Sokol, 2007;Panina, Zaitsev, 2012]. Целью данного исследования является определение глубинной геоэлектрической структуры Салаира и ее сопоставление с геологическим строением и неотектоническим структурным планом региона.…”
