Динамика новейших орогенических движений и трансгрессивно-регрессивных циклов Понто-Каспия предопределила развитие горного рельефа Западного Кавказа и суши – Предкавказья. Обобщены данные о строении и корреляции сводных разрезов моласс Западного Предкавказья, составленных на основе многолетнего изучения, а также био- и магнитостратиграфического датирования. Выделены циклы накопления континентальных отложений Западного Предкавказья, коррелятные основным этапам формирования орогена. Оценена динамика новейших поднятий Западного и Северо-Западного сегментов орогена, разделенных Пшехско-Адлерской зоной разломов. Приводятся данные о существовании суши Западного Кавказа в среднем и Северо-Западного – в позднем миоцене. Установлено, что первый импульс горообразования Западного Кавказа относится к сармату, а его резкое ускорение – к квартеру. Составленная серия палеогеографических карт Западного Кавказа и Предкавказья в неогене–квартере отражает динамику кавказской орогении, береговых линий Предкавказских морей и историю формирования речной сети территории. Установлено, что неоген-четвертичная речная сеть Западного Кавказа и Предкавказья выстроена в виде трех зон, отвечающих по возрасту различным этапам становления орогена. Каждой из них свойственна собственная ориентировка палеодолин, связанная с конфигурацией поднятых на разных этапах водораздельных поверхностей в их истоках и береговых линий, принимающих морских или озерных бассейнов – в устьях.
