The anatomy and evolution of a transpressional imbricate zone, Southern Uplands, Scotland

A new tectonic model for the Palaeoproterozoic Kautokeino Greenstone Belt, northern Norway, based on high-resolution airborne magnetic data and field structural analysis and implications for mineral potential

“…When comparing the gneissic sequences of the Jergul transpression (e.g., Holdsworth et al, 2002;Jones et al, 2004;Tavarnelli et al, 2004;Bergh et al, 2010;2015;Viola & Henderson, 2010;Angvik, 2014). Shearing along the NNW-SSE-trending western KkGB postdates the 1865 Ma Vuolgamašvuopmi granite (area D in Fig.…”

“…This is because ductile shear zones at all scales are an essential part of any orogenic belt, often accommodating strain during polyphase deformation histories (e.g., Sanderson & Marchini, 1984;Jones & Tanner, 1995;Tavarnelli et al, 2004). Geometric and kinematic models derived from their in depth analysis are thus of key importance and, when combined with geochronological data, place tight constraints on orogen build up and collapse processes.…”

Transpressional tectonics and nappe stacking along the Southern Variscan Front of Morocco

“…Oldow et al 1990;Tikoff and Teyssier 1994;Jones and Tanner 1995;Dewey et al 1998) has been described in many orogenic belts and invoked to explain their structural complexity (Brun and Burg 1982;Hubbard and Mancktelow 1992;Cerrina Feroni et al 2004;Tavarnelli et al 2004;Malusà et al 2009). …”

Thrusting and transpressional shearing in the Pan-African nappe southwest El-Sibai core complex, Central Eastern Desert, Egypt

“…Changes in tectonic regime from compressional arcaccretion setting to an extensional regime is due to extensional collapse, which resulted from an increase in resistance of the down-going plate due to buoyancy forces (Thompson et al, 2001;Ngako et al, 2003;El-Bahariya and Abd El-Wahed, 2003;Acosta et al, 2004;Tavarnelli et al, 2004;Knopásek et al, 2005). Rapid exhumation of the Neoproterozoic core complex in Wadi Kid area of the Sinai was initiated when lateral buoyancy forces exceeded horizontal driving forces (Blasband et al, 2000;Brooijmans et al, 2003).…”
