Investigations and Problems of Southern California Geology [PDF]

open access: yes, 1954
Recognition of geologic features and processes by the peoples of southern California dates back at least several thousand years, when Indian tribes lived in some of the coastal areas and on the shores of now-extinct lakes farther inland.

Modeling singular mineralization processes due to fluid pressure fluctuations [PDF]

open access: yes, 2020
Mineralization in the Earth's crust can be regarded as a singular process resulting in large amounts of mass accumulation and element enrichment over short time or space scales. The elemental concentrations modeled by fractals and multifractals show self-

Digital documentation of railway tunnel inspection in Austria

open access: yesCivil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.
Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.

Effective crustal permeability controls fault evolution: An integrated structural, mineralogical and isotopic study in granitic gneiss, Monte Rosa, Northern Italy [PDF]

open access: yes, 2016
Two dextral faults within granitic gneiss in the Monte Rosa nappe, northern Italy reveal key differences in their evolution controlled by evolving permeability and water/rock reactions.

Photogrammetric documentation in tunneling

open access: yesCivil Engineering Design, EarlyView.
Abstract Photogrammetric surveys for geological excavation documentation are standard practice in tunnel construction, benefiting from the sector's ongoing digitalization. However, the application of photogrammetry often remains confined to geological assessments. By creating comprehensive 3D models of excavated tunnels, it is also possible to evaluate

Weighing risks against GHG reduction benefits in emerging green technologies

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Green technologies represent promising strategies for mitigating carbon emissions and combating global warming. However, their implementation in civil and industrial applications is not without risks, as intrinsic uncertainties and latent safety concerns can threaten their effective deployment.

Natural resources inventory and monitoring in Oregon with ERTS imagery [PDF]

open access: yes
Multidiscipline team interpretation of ERTS satellite and highflight imagery is providing resource and land use information needed for land use planning in Oregon. A coordinated inventory of geology, soil-landscapes, forest and range vegetation, and land

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).
