Post-rift pelagic-hemipelagic sequence is classified as a parallel layer with moderate to high continuous reflections, moderate amplitude with varying frequency. This sequence is generally considered to be deposited in a deep-water condition. The highly faulted syn-rift package is unconformably overlai...

Recent studies indicate that a prominent tear in the Indian lithosphere, sub-parallel to the rift, is the most likely source of the tectonic-thermal anomalies, responsible for remelting the lithospheric mantle and lower crust (Luo et al., 2022; Wang et al., 2022). The UPVs mainly erupted ...
Rocks are classified as monzo-diorites, monzonites, quartz-monzonites and granites and plot mostly below the alkaline suite line on the TAS diagram (Fig. 8A). Total alkali contents are high (7.61 wt.% to 9.53 wt.%) and the K2O/Na2O ratio is greater than 1.0, with signatures close to...
These units occur along the SW termination of the Alto Moxotó Terrane of the Borborema Province and, despite the influ- ence of the Brasiliano-related shear zones, this region preserves old lithosphere, providing a unique opportunity to unravel hidden crustal processes within a Neoproterozoic ...
The samples are classified as andesite, dacite, trachyandesite and trachyte on the TAS diagram (Fig.5b) and as andesites on the Nb/Y-SiO2diagram (Fig.5c). The rocks share a similar composition that is consistent with Permian calc-alkaline magmatism of the Iberian Chain (Lago et al.,2004...
Pedosphere: Used interchangeably with soil and captures the concept that the soil is a habitat where the integration of rock (lithosphere), air (atmosphere), water (hydrosphere), and living things (the biosphere) occurs. (Brady & Weil 2002) ...

2011). The latter number takes into account the mechanical state of the lithosphere, porosity of the crust and calculates the depth at which the pores/fractures would close due to plastic deformation. This number could act as an upper limit for present-day Venus, considering the higher surface...
The mantle-crust boundary of the northern Pannonian lithosphere is derived from geophysical data in Dérerová et al. (2006) Full size image Temperatures around 800 °C are constrained by the P-saturation limit of calcic carbonatite with 51–51.5 wt% CaO dissolving ~ 0.6 wt% P2O5. ...
