Widespread erosion on high plateaus during recent glaciations in Scandinavia [PDF]

, 2018
Glaciers create some of Earth’s steepest topography; yet, many areas that were repeatedly overridden by ice sheets in the last few million years include extensive plateaus.

Petrochemical Characteristics of Cenozoic Basalts in Datong, Shanxi

Taiyuan Ligong Daxue xuebao, 2021
Basalt in the Cenozoic period in Datong, Shanxi can be divided into two types: alkaline basalt in the northwest and tholeiite basalt in the southeast. Petrological and geochemical analyses were carried out on the basalts in Datong area. As known from the

On the origin of the North Pacific arcs [PDF]

, 2004
We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean.

Pliocene adakite-like accent of andesites and dacites from the Orlov volcanic field (Sakhalin Island)

Геосистемы переходных зон, 2021
Adakite-like geochemical signature (high Sr/Y ratio at a low Y concentration) is recognized in andesites and dacites, associated with intraplate basalts in the Orlov volcanic field of Sakhalin Island.

Early Cenozoic denudation of central west Britain in response to transient and permanent uplift above a mantle plume [PDF]

, 2018
Upwelling mantle plumes beneath continental crust are predicted to produce difficult to quantify, modest uplift and denudation. The contribution of permanent and transient components to the uplift is also difficult to distinguish.

Petrochemistry and origin of basalt breccia from Ban Sap Sawat area, Wichian Buri, Phetchabun, central Thailand [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2013
Thailand is usually considered to be controlled by escape tectonics associated with India-Asia collision during theLate Cenozoic, and basaltic volcanism took place in this extensional period.

Geodynamic conditions for Cenozoic activation of tectonic structures in Southeastern Mongolia

Геодинамика и тектонофизика, 2018
The knowledge of the neotectonic structures inSoutheastern Mongolia, that is considerably distant from the active plate boundaries, is important for determining a source of tectonic deformation and regular features of activation in the intracontinental ...

The karst and palaeokarst of North and North-East Greenland – physical records of cryptic geological intervals

GEUS Bulletin, 2022
Carbonate rocks of Neoproterozoic to Silurian age are abundantly distributed around the coasts of North and North-East Greenland. Palaeokarst horizons are particularly well developed within the Portfjeld Formation (Ediacaran – earliest Cambrian) and ...

Stable oxygen and carbon isotope compositional fields for skeletal and diagenetic components in New Zealand Cenozoic nontropical carbonate sediments and limestones: a synthesis and review [PDF]

, 1996
The stable oxygen isotope composition (d¹⁸O) of a precipitated carbonate depends mainly on the isotope composition, salinity, and temperature of the host fluid, whereas the stable carbon isotope composition (d¹³C) reflects the source of CO2 for ...
