ГЕОЛОГИЧЕСКАЯ ХАРАКТЕРИСТИКА И ЭКОЛОГИЧЕСКИЕ АСПЕКТЫ ОСВОЕНИЯ СКАРНОВОГО ЖЕЛЕЗОРУДНОГО МЕСТОРОЖДЕНИЯ ЖУАНТОБЕ

Скарновые железорудные месторождения являются важной составляющей мировой сырьевой базы железа, однако их освоение, как правило, сопровождается значительным воздействием на окружающую среду вследствие масштабных открытых горных работ. В настоящем исследовании представлена комплексная геологическая и геоэкологическая оценка Жуантобинского скарнового железорудного месторождения (Центральный Казахстан) с акцентом на взаимосвязь процессов рудообразования и реакции окружающей среды в условиях действующего горного производства. В работе объединены геологические, минералогические, геохимические, геофизические данные, а также результаты долгосрочного экологического мониторинга за период 2018–2025 гг. Рудные тела характеризуются сложной морфологией, контролируемой разрывными нарушениями и многостадийной эволюцией скарнообразования, включая проградную (гранат–пироксеновую) и ретроградную (магнетит–сульфидную) стадии. Результаты экологического мониторинга свидетельствуют о систематическом снижении антропогенной нагрузки, в том числе уменьшении пылевой нагрузки (>40%), содержания железа в почвах (~40%) и выбросов CO₂ (~35%). Показано, что реализация комплекса природоохранных мероприятий обеспечивает стабилизацию экологических показателей в пределах допустимых нормативов. В работе предложена концептуальная модель, связывающая геологическое строение месторождения с экологическими характеристиками, а также сформулирован комплекс универсальных подходов к устойчивому освоению скарновых железорудных месторождений.
