Quantitative evaluation method of fault lateral sealing

open access: yesPetroleum Exploration and Development, 2016
The fault-reservoir displacement pressure differential method, as a quantitative evaluation method of fault sealing which considering diagenetic time of fault rock, was improved based on the study of fault sealing mechanism and its influencing factors. A

Contrasting stress fields on correlating margins of the South Atlantic [PDF]

open access: yes, 2015
The “passiveness” of passive continental margins across the globe is currently under debate since several studies have shown that these margins may experience a variety of stress states and undergo significant vertical movement post-breakup.

Control of bedrock geology on active structural deformation revealed by changes in geomorphic parameters: A case study of the Fodongmiao-Hongyazi Frontal Thrust, NE Tibet

open access: yesDizhi lixue xuebao
Objective  Widely distributed active faults are natural carriers that produce surface-rupture events; multidisciplinary observations have revealed that geometric changes in active faults significantly influence surface-rupture development.

Deformation of continental crust along a transform boundary, Coast Mountains, British Columbia [PDF]

open access: yes, 2010
New structural, paleomagnetic, and apatite (U-Th)/He results from the continental margin inboard of the Queen Charlotte fault (~54°N) delineate patterns of brittle faulting linked to transform development since ~50 Ma.

Geology of the Transverse Range Province, Southern California [PDF]

open access: yes, 1954
The Transverse Range province of southern California is an elongate geomorphic and structural unit that trends essentially east-west across parts of Santa Barbara, Ventura, Los Angeles, San Bernardino, and Riverside Counties (pl. 4).

Benefits of a 3D geological model for major tunnelling works : an example from Farringdon, east-central London, UK [PDF]

open access: yes, 2012
In the design of major construction works, the better the ground conditions are known, the more control there is on the assessment of risks for construction, contract and personnel, and ultimately on final costs. Understanding of the ground conditions is

Unveiling Aggregation‐Induced Singlet Fission in Push–Pull Diketopyrrolopyrrole Water Dispersed Nanoaggregates and Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Aggregates of diketopyrrolopyrrole dipolar and quadrupolar systems exhibit panchromatic absorption spectra extending in the entire visible range. Upon aggregation in water and in the solid state, their fluorescence is almost completely quenched and their singlet excited state lifetime is significantly shortened.

Analytical Solution for the Frictional Anisotropy of a Corrugated Fault

open access: yesGeophysical Research Letters
Fault surfaces exhibit anisotropic roughness, with elongate ridges and grooves aligned in the slip direction. When inactive faults are reactivated under a new stress regime, induced by natural processes or human activities, the maximum resolved shear ...

Hydrogeological structure model of the fault zone in the karst area of north China

open access: yesCarsologica Sinica, 2022
The fault zone has a controlling effect on the mechanical properties and fluid flow characteristics of the crust. It is an extensively distributed and very important structural pattern in the upper crust, and widely participates in the crustal activity ...

Scale-dependence of lithological control on topography: Bedrock channel geometry and catchment morphometry in western Scotland [PDF]

open access: yes, 2010
We propose that a scale-dependent topographic signature of erodibility arises due to fluvial and glacial erosion acting on different parts of the landscape at different times.
