Marine geoheritage comprises unique geological features of modern and ancient seas and oceans. The Russian Altai (southern Siberia) is a vast and geologically rich area, which was covered by a marginal sea of the Panthalassa Ocean in the Devonian. New geosites representing shallow- and deep-marine depositional environments and palaeoecosystems of submarine volcano slopes are proposed, namely, Melnichnye Sopki and Zavodskie Sopki. They are located near the town of Zmeinogorsk (Altai Region of the Russian Federation). These pieces of marine geoheritage are valuable on an international scale. Special geoconservation procedures are recommended to manage the proposed geosites efficiently. They can be included in a geopark, which is reasonable to create due to the concentration of geological and mining heritage in the study area.

俄罗斯阿尔泰的新海洋地质遗迹

海洋地质遗迹具有现代和古代海洋的独特地质特征。俄罗斯的阿尔泰（西伯利亚南部）是一个广阔而地质丰富的地区，被泥盆纪的潘塔拉萨海洋边缘海所覆盖。提出了代表浅海和深海沉积环境以及海底火山斜坡古生态系统的新地理位置，即Melnichnye Sopki和Zavodskie Sopki。他们位于Zmeinogorsk镇（俄罗斯联邦的阿尔泰地区）附近。这些海洋地质遗迹在国际上具有重要价值。建议采用特殊的地质保护程序，以有效管理建议的地理位置。它们可以包含在地质公园中，由于研究区域中地质和采矿遗产的集中，因此可以合理地创建它们。
