Integrated geophysical and geological investigations applied to sedimentary rock mass characterization

open access: yesAnnals of Geophysics, 2008
The Salento Peninsula (south-eastern Italy) is characterized by sedimentary rocks. The carbonatic nature of the rocks means they are affected by karst phenomena, forming such features as sinkholes, collapsed dolines and caverns, as a result of chemical ...

Fault rock evolution and fluid flow in sedimentary basins [PDF]

open access: yes, 1989
Structural studies have been undertaken in two extensional fault regimes associated with post-Caledonian basin-forming events in northern Scotland. A combination of detailed mapping and microstructural analysis has revealed the deformation processes and ...

Characterisation of sedimentary structure and hydraulic behaviour within the unsaturated zone of the Triassic Sherwood Sandstone aquifer in North East England [PDF]

open access: yes, 2004
A study of the sedimentological framework and permeability characteristics of the Sherwood Sandstone has been undertaken together with a detailed investigation of moisture migration in the vadose zone at a single field site.

Depositional environment of Jurassic deposits in the Binalud basin, according to the provenance and paleo-tectonic setting, northwest of Mashhad, Iran [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2021
The thick Jurassic fluvial coarse-grained sediments rest non-conformably on older metamorphic rocks to the northwest of Mashhad. Two sections, 300 and 400 m thick, were measured and studied through the Jurassic deposits.

Types of fine-grained sedimentary rocks assemblage and its significance for shale oil exploration: A case study of the fifth member of Xujiahe Formation in western Sichuan Depression, Sichuan Basin [PDF]

open access: yesYouqicang pingjia yu kaifa, 2023
Due to the complex lithology of fine-grained sedimentary rocks and the difficulty to determine the “sweet spot” of the fifth member of Xujiahe Formation(short for Xu-5 Member) of western Sichuan Depression, Sichuan Basin, a comprehensive geological ...

Discussion on classification and naming scheme of fine-grained sedimentary rocks

open access: yesPetroleum Exploration and Development, 2022
Based on reviews and summaries of the naming schemes of fine-grained sedimentary rocks, and analysis of characteristics of fine-grained sedimentary rocks, the problems existing in the classification and naming of fine-grained sedimentary rocks are ...

Study on sedimentary facies characteristics of Xujiahe Formation in Sichuan Basin [PDF]

open access: yesE3S Web of Conferences, 2021
Sedimentary facies is the summation of all primary sedimentary features in a sedimentary unit, which is the product of sedimentation in a specific environment. It emphasizes the material performance of sediment formation conditions, including mineralogy,

Study of a damage constitutive model for water-bearing coal measures sedimentary rock with nonlinear deformation during compaction stage

open access: yesGeohazard Mechanics, 2023
The problem of repeated immersion-induced fatigue damage in engineering coal measures sedimentary rock, including coal-rock pillars, reservoir bank slopes, and water-rich tunnels at the boundary of coal mine underground reservoirs, has profound ...
