Abstract

Localization of the finds of natural bitumen in archipelagos in the western segment of the Russian Arctic is considered. The nature of their appearance in relation with the subsurface geothermal regime is discussed. Based on numerical simulation, temperatures and heat flow density are calculated in 2D geometry along seismogeological profiles and in 3D geometry for the isometric structure of Franz Josef Land. It is concluded that all the noted natural bitumen manifestations are genetically related to hydrothermal activity, with signs adequately recorded in the geotemperature field.

巴伦支地区群岛俄罗斯段（法兰士约瑟夫地群岛、新地岛）有机物灾变的热压条件

摘要

考虑在俄罗斯北极西段的群岛中发现天然沥青。讨论了它们的外观性质与地下地热状态的关系。基于数值模拟，沿着地震地质剖面以 2D 几何形式计算法兰士约瑟夫地群岛等轴结构的温度和热流密度，并以 3D 几何形式计算温度和热流密度。结论是，所有注意到的天然沥青表现都与热液活动在遗传上相关，并且在地温场中充分记录了迹象。
