Straight impact crater rim segments on Mercury

open access: yesJournal of Maps
The formation of straight impact crater rims is widely accepted to be influenced by preexisting lithospheric structure. We investigate the distribution and orientations of straight crater rim segments across Mercury. We devise a mapping workflow aimed at

Characteristics of in situ stress and its influence on coalbed methane development: A case study in the eastern part of the southern Junggar Basin, NW China

open access: yesEnergy Science & Engineering, 2020
Based on 54 sets of well test data of 29 coalbed methane (CBM) wells, the distribution characteristic of in situ stress in the eastern part of the southern Junggar Basin and its control on permeability (K), reservoir pressure (Po), and gas content (G ...

The Fine Structure Constant and Habitable Planets

open access: yes, 2016
We use the existence of habitable planets to impose anthropic requirements on the fine structure constant, $\alpha$. To this effect, we present two considerations that restrict its value to be very near the one observed.

Digital Tectonics as a Morphogenetic Process

open access: yes, 2010
p. 938-948Tectonics is a seminal concept that defines the nature of the relationship between architecture and its structural properties. The changing definition of the symbiotic relationship between structural engineering and architectural design may ...

Mineralogy and geochemistry of the Cambrain Shuijingtuo Formation black shales from Western Hubei, China: implications on enrichment of critical metals and paleoenvironment

open access: yesFrontiers in Marine Science
Black shales have attracted the attention of numerous researchers not only due to their high potential as hydrocarbon source rocks and shale gas reservoirs, but also to the enrichment of critical metal elements in black shale series.

A Global Plate Model Including Lithospheric Deformation Along Major Rifts and Orogens Since the Triassic [PDF]

open access: yes, 2019
Global deep‐time plate motion models have traditionally followed a classical rigid plate approach, even though plate deformation is known to be significant.

Curie Point Depths of the Amur Tectonic Plate

open access: yesRussian Journal of Earth Sciences
Based on the analysis of the anomaly magnetic field for the Amur Plate and adjacent territories, a Curie Point Depth (CPD) map has been constructed, which we identify with the isotherm 578°C — the temperature of the Curie point of magnetite.

Formation and Identification of Unresolved Complex Mixtures in Lacustrine Biodegraded Oil from Nanxiang Basin, China

open access: yesThe Scientific World Journal, 2014
A comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry (GC × GC/TOFMS) method has been developed for the formation and identification of unresolved complex mixtures (UCMs) in lacustrine biodegraded oils that with the same ...

Effects of Seismogenic Faults on the Predictive Mapping of Probability to Earthquake-Triggered Landslides

open access: yesISPRS International Journal of Geo-Information, 2019
The seismogenic fault is crucial for spatial prediction of co-seismic landslides, e.g., in logistic regression (LR) analysis considering influence factors.
