ABSTRACT

The Kamchatka Peninsula lies on the eastern active margin of Eurasia, adjacent to the Kuril-Kamchatka subduction zone. In this study, we provide a geomorphological map of the Central Kamchatka Depression – the largest sedimentary basin in Kamchatka and also in all the island arcs of the North Pacific. The depression extends along Kamchatka at latitudes ∼44–46° N for more than 400 km and is up to 100 km wide. The geomorphological map of the Central Kamchatka Depression is designed at a scale of 1:500,000 and contains ∼3000 mapped objects. Volcanic and tectonic landforms have been collected from published sources and generalised to the map scale. Glacial and fluvial landforms have been mapped using remote sensing data and field geomorphological surveys. Areas of ambiguous interpretation have been outlined. This map is the most detailed geomorphological map published for this region that may guide further geomorphological and paleogeographical investigations.

摘要

堪察加半岛位于欧亚大陆东部活动边缘，毗邻千岛堪察加俯冲带。在这项研究中，我们提供了堪察加半岛中部凹陷的地貌图——堪察加半岛以及北太平洋所有岛弧最大的沉积盆地。该洼地沿着北纬~44-46°的堪察加半岛延伸超过400公里，最宽可达100公里。堪察加凹陷中部地貌图的设计比例为 1:500,000，包含约 3000 个测绘对象。火山和构造地貌是从已发表的来源收集的，并推广到地图比例尺。利用遥感数据和实地地貌调查绘制了冰川和河流地貌图。已经概述了解释不明确的领域。
