Abnormal heat flow and the trough’s nature in the Northern Svalbard plate

Abnormal heat flow in the Northern Svalbard plate was investigated. The study discovered the recent activity of western troughs (the Orel trough and Spitsbergen grabenfjords); we cannot state the same for eastern troughs (the Franz Victoria trough and others). Their tectonic origin is quite evident,...

Description
Summary:Abnormal heat flow in the Northern Svalbard plate was investigated. The study discovered the recent activity of western troughs (the Orel trough and Spitsbergen grabenfjords); we cannot state the same for eastern troughs (the Franz Victoria trough and others). Their tectonic origin is quite evident, but the peak of activity occurred in the late Mesozoic [5, 6], and at present, in addition to the relaxation of the Cretaceous thermal activity, they might serve as channels for sedimentary material transport.
