Аннотация

Геологическое изучение разрезов мезозоя архипелага Новосибирские острова, наряду с разрезами азиатского побережья Северного Ледовитого океана, играет ключевую роль для увязки полученных результатов комплексных исследований с данными сейсмических методов изучения шельфа моря Лаптевых и запада Восточно-Сибирского моря. Поэтому крайне актуально совершенствование расчленения триасовой системы Новосибирского архипелага и определение места системы в структуре осадочного бассейна лаптевоморского шельфа. Проведенные исследования позволили усовершенствовать и детализировать литостратиграфическое расчленение триаса этого региона и проследить в этом регионе яркий межрегиональный маркирующий стратиграфический репер - чекановскую свиту (нижний оленек). Генетические, структурные и седиментологические особенности строения триасовых толщ позволяют объединить их в две серии: решетниковскую (инд-верхний ладин) и светлую (ладин-рэт), отражающие крупные этапы седиментогенеза. Для триаса восточных районов лаптевоморского шельфа и прилегающей суши на единой основе разработано и уточнено фациальное районирование. Анализ строения фанерозойских разрезов территории позволяет рассматривать их в составе промежуточного структурного этажа Лаптевоморской плиты на периферии Сибирского кратона.
