Применение функции взаимной корреляции для картирования сдвигов по данным потенциальных полей (на примере трансформных разломов хребта Колбейнси)

N. P. Senchina, A. E. Asoskov, D. A. Matykina

Аннотация


В работе представлены результаты опробования алгоритма оценки амплитуды сдвига на смоделированном (искусственно синтезированном) поле и на реальном магнитном поле окрестностей хребта Колбейнси. Алгоритм основан на расчете в пределах площади исследования характеристик взаимнокорреляционной функции в скользящих окнах и позволяет количественно оценить амплитуду сдвига и определить его лево- или правостороннюю кинематику. Подход реализован в форме авторской программы WindowXCorr. Тестирование на модели и на реальных данных показало работоспособность алгоритма и наличие негативных элементов в результатах расчета, что говорит о потенциале данного подхода и необходимости его доработки с учетом сложности и полигенности реальных геофизических данных.
