      <abstract xml:lang="ru">
        <p>Перед рентгенометрическим исследованием ставились следующие задачи: установить аморфную или кристаллическую природу образцов; выяснить, имеются ли существенные структурные изменения для раз­личных образцов гуммитов, обособляемых по морфологическим призна­кам в разновидности; выявить, по возможности, причины структурных особенностей различных образцов; дать рентгенометрические эталоны для гуммитов, сравнив их с имеющимися в литературе результатами рентгенометрических исследований этих минералов; проследить харак­тер изменений минералов при их термической обработке. Работа выполнялась в рентгенометрической лаборатории Федоров­ского института при Ленинградском горном институте в 1948 г.</p>

        <p>The following tasks were set before the X‑ray diffractometric study: to establish amorphous or crystalline nature of samples; to find out whether there are significant structural changes for different samples of gummites, isolated by morphological features into varieties; to identify, if possible, the reasons for the structural features of different samples; to give X‑ray diffractometric standards for gummites, comparing them with the results of X‑ray diffractometric studies of these minerals available in the literature; to trace the nature of changes in minerals during their heat treatment. The work was carried out in the X‑ray diffractometric laboratory of the Fedorovsky Institute at the Leningrad Mining Institute in 1948.</p>
