, 2018 The idea that plate tectonics may not have operated deep in Earth's Precambrian past has a long legacy. What predated plate tectonics is unknown, and advances in data – from geochemical, geological and tectonic, to paleomagnetic, as well as modelling ...

The Effect of Obliquity of Slip in Normal Faults on Distribution of Open Fractures
Frontiers in Earth Science, 2019 Close to surface, cohesive rocks fail in extension, which results in open fractures that can be several tens of meters wide, so-called massively dilatant faults. These open fractures make fault slip analysis in rifts challenging, as kinematic markers are

Multiphase boudinage: a case study of amphibolites in marble in the Naxos migmatite core [PDF]
Solid Earth, 2018 In multiply deformed terrains multiphase boudinage is common, but identification and analysis of these is difficult. Here we present an analysis of multiphase boudinage and fold structures in deformed amphibolite layers in marble from the migmatitic ...

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о ЗемлеThe paper considers the possibility of determining the age and correlating peat sections by solving the inverse problem of magnetostratigraphy based on the findings of comprehensive (palaeomagnetic, petromagnetic, microprobe, and radiocarbon) studies on ...

Observing eruptions of gas-rich compressible magmas from space
Nature Communications, 2016 Satellite observations are an important tool in volcano monitoring, but observations such as ground deformation and gas emissions are treated independently. Here, the authors present a model coupling them through their link to magma volatile contents and

Present-day stress orientations and tectonic provinces of the NW Borneo collisional margin [PDF]
, 2010 Extent: 15p.Borehole failure observed on image and dipmeter logs from 55 petroleum wells across the NW Borneo collisional margin were used to determine maximum horizontal stress (σH) orientations; combined with seismic and outcrop data, they define seven

Icarus, 2017 New Horizons images of Pluto's companion Charon show a variety of terrains that display extensional tectonic features, with relief surprising for this relatively small world. These features suggest a global extensional areal strain of order 1% early in Charon's history.
