This paper presents the experiences obtained in the application of Principal Component Analysis (PCA) method to map hydrothermal minerals based on remotely sensed data. In this study, Sentinel-2B MultiSpectral Instrument (MSI) image is used to detect distribution of hydroxyl-bearing minerals in Vinh Phuc province, northern Vietnam. Four bands of Sentinel-2B image including blue band (band 2), Vegetation Red Edge band (band 8A) and SWIR bands (band 11 and 12) are used to calculate the Principal Components, then and then select the Principal Component, which containing provides information on the hydrothermal minerals information. The obtained results findings show that the methodology and data are effective in detecting and mapping hydrothermal mineralization.

В данной статье представлен опыт, полученный при применении метода анализа главных компонентов (PCA) для картирования гидротермальных минералов на основе данных дистанционного зондирования. В этом исследовании изображения, полученные посредством дистанционного (спутникового) зондирования с использованием спектрозонального прибора Сентинель 2Б, используются для определения распределения минералов, содержащих гидроксил, в провинции Винь-Пхук, Северный Вьетнам. Четыре полосы (диапазона) изображения Сентинель 2Б, включая синюю полосу (полоса 2), полосу растительности (красный (длинноволновый) край спектра) (полоса 8A) и полосы SWIR (коротковолновая ИК область спектра, полосы 11 и 12), используются для расчета главных компонентов, а затем выбирается главный компонент, несущий информацию о гидротермальных минералах. Полученные результаты показывают, что рассматриваемые методология и данные эффективны при обнаружении и картировании гидротермальной минерализации.
