      <abstract xml:lang="ru">
        <p>Известно, что все объекты в геологии имеют пределы как в про­странстве, так и во времени. Эти пределы не бесконечны. Гранины их носят различный характер, причем типы границ близки для объектов и явлений, изменяющихся как во времени, так и в пространстве.</p>

      <abstract xml:lang="en">
        <p>It is known that all objects in geology have limits both in space and time. These limits are not infinite. Their boundaries are of different character, and the types of boundaries are close for objects and phenomena changing both in time and in space.</p>
