Новые высокобарические полиморфные модификации магнетита, ильменита, оливина, пироксенов и полевых шпатов

Новые высокобарические минералы, прису тствующие в метеоритах, испытавших ударные воздействия, могут рассматриваться как вероятные компоненты глубинных геосфер. В статье дана характеристика структурных особенностей недавно открытых минералов этого генетического типа, представляющих геофизический интерес. Особое внимание обращено на новые данные о структурных трансформациях в глубинных оболочках Земли (Fe,Ti) — оксидов со структурами типа ильменита и постшпинельных фаз, высокобарических модификаций магнетита, оливина, пироксенов и полевых шпатов. Структуры и состав новых НР-минералов из импактных зон, метеоритов и алмазных включений несут информацию о сложной петрологии глубинных геосфер, которая не может проявиться  в продуктах лабораторных экспериментов, а также позволяют спрогнозировать их роль как возможных транспортеров крупных катионов в мантии Земли, влияющих на тепловой режим Земных недр.
