Геоэлектрическая модель NARYN, проходящая вдоль меридиана 76° в.д. через Центральный Тянь-Шань от Казахского щита до Таримской платформы, является одним из самых протяженных сечений во внутриконтинентальной Азии. В данной статье дан исторический обзор геоэлектрических моделей по данным магнитотеллурических (МТ) зондирований 1999–2000 гг. и 2005 г. Показаны две построенные на основе этих данных с помощью разных алгоритмов инверсии: дискретно-сглаженной модели NARYN-RLM и кусочно-непрерывной модели NARYN-INV2D. Рассматривается локальный каталог землетрясений за 1980–2022 гг. Распределения гипоцентров из четырех региональных и глобальных сейсмических каталогов наложены на эталонный поперечный разрез для повторной проверки ранее выявленной взаимосвязи между проводимостью земной коры и распределением землетрясений по глубине. Отмечается, что слабая сейсмичность в основном сосредоточена над верхней границей средне- и нижнекорового проводника, тогда как самые сильные события группируются в резистивных, консолидированных блоках земной коры или на их контактах с проводящими зонами.

The “NARYN” geoelectric model, which runs along the 76° E meridian through the Central Tien Shan from the Kazakh Shield to the Tarim Platform, is one of the longest cross-sections in continental Asia. This paper provides a historical overview of geoelectric models based on magnetotelluric (MT) soundings from 1999-2000 and 2005. Two inversion models constructed from these data using different algorithms are presented: the discrete-smoothed NARYN-RLM model and the piecewise continuous NARYN-INV2D model. A local earthquake catalog for 1980­2022 is considered. Hypocenter distributions from four regional and global seismic catalogs are superimposed on a reference cross-section to re-examine the previously identified relationship between crustal conductivity and earthquake depth distribution. It is noted that weak seismicity is mainly concentrated above the upper boundary of the middle and lower crustal conductor, while the strongest events are grouped in resistive, consolidated blocks of the earth’s crust or at their contacts with conductive zones.
