Energetics of the Citric Acid Cycle in the Deep Biosphere

open access: yesGeophysical Monograph Series, Page 303-327., 2020

This book is Open Access. A digital copy can be downloaded for free from Wiley Online Library.

Explores the behavior of carbon in minerals, melts, and fluids under extreme conditions

Carbon trapped in diamonds and carbonate-bearing rocks in subduction zones are examples of the continuing exchange of substantial carbon ...

Research on the characteristics and influencing factors of terrestrial heat flow in Guizhou Province

open access: yesJournal of Groundwater Science and Engineering, 2022
Terrestrial heat flow is an important physical parameter in the study of heat transfer and thermal structure of the earth and it has great significance in the genesis and development and utilization potential of regional geothermal resources.

Seismological structure of the 1.8 Ga Trans-Hudson Orogen of North America [PDF]

open access: yes, 2016
Precambrian tectonic processes are debated: what was the nature and scale of orogenic events on the younger, hotter, and more ductile Earth? Northern Hudson Bay records the Paleoproterozoic collision between the Western Churchill and Superior plates—the ∼

Moho Geometry Estimation Beneath the Gulf of Guinea From Satellite Gravity Data Based on a Regularized Non‐Linear Gravity Inversion

open access: yesEarth and Space Science, 2023
In this work, we present a new gravimetric Moho model over the Gulf of Guinea computed from the inversion of the global gravity EIGEN‐6C4 model. The computation procedure contains a regularized non‐linear inversion algorithm.

Moho depth inversion in the Tibetan Plateau from high-precision gravity data

open access: yesEarth and Planetary Physics, 2023
The Tibetan Plateau (TP) is the youngest orogenic belt resulting from a continental collision on the Earth. It is a natural laboratory for studying continental dynamics, such as continental convergence, plate subduction, and plateau uplift. Investigating

Global crustal thickness from neural network inversion of surface wave data [PDF]

open access: yes, 2007
We present a neural network approach to invert surface wave data for a global model of crustal thickness with corresponding uncertainties. We model the a posteriori probability distribution of Moho depth as a mixture of Gaussians and let the various ...

Moho and uppermost mantle structure in the Alpine area from S-to-P converted waves [PDF]

open access: yesSolid Earth, 2021
In the frame of the AlpArray project we analyse teleseismic data from permanent and temporary stations of the Alpine region to study seismic discontinuities down to about 140 km depth.

Effective elastic thickness in the Central Andes. Correlation to orogenic deformation styles and lower crust high-gravity anomaly [PDF]

open access: yes, 2018
Global studies have assessed the importance of elastic thickness (Te) on orogenic evolution, showing that the style and nature of upper crustal shortening are influenced by the inherited lithospheric strength. Thus, pioneer works have identified that the

Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina [PDF]

open access: yes, 2017
The North Patagonian Massif is an Argentinean plateau that has an average height of 1200 m and stands from 500 to 700 m above the neighboring areas. During Paleogene, it suffered a sudden uplift of more than 1200 m without noticeable internal deformation;

An Approach to Moho Topography Recovery Using the On-Orbit GOCE Gravity Gradients and Its Applications in Tibet

open access: yesRemote Sensing, 2019
It is significant to determine the refined Moho topography for understanding the tectonic structure of the crust and upper mantle. A novel method to invert the Moho topography from the on-orbit gravity gradients is proposed in the present study. The Moho
