How Mobile Are Sorbed Cations in Clays and Clay Rocks?

Environmental Science & Technology, 2011
Diffusion of cations and other contaminants through clays is of central interest, because clays and clay rocks are widely considered as barrier materials for waste disposal sites. An intriguing experimental observation has been made in this context: Often, the diffusive flux of cations at trace concentrations is much larger and the retardation smaller ...

Rock-physics templates for clay-rich source rocks

GEOPHYSICS, 2015
Shale source rocks are composed of various minerals, mainly smectite and illite, depending on the burial depth, and they can be described as transversely isotropic media. The “pore space” may contain kerogen, water, oil, and gas determined by the in situ conditions.

Clay-shoveler’s Fracture During Indoor Rock Climbing

Orthopedics, 2013
Indoor rock climbing is becoming more popular for people of all ages. Despite the tremendous interest in this competitive sport, participants are made aware of the dangers associated with participating. The authors present the first reported case of a clay-shoveler’s fracture at the T1 spinous process during indoor rock climbing.

Using clay rock in smelting ferrosilicoaluminum

Steel in Translation, 2008
The possibility of smelting ferrosilicoaluminum (57–60% Si, 28–35% Al) from high-ash (≥65%) waste clay rock is considered. Additions of high-ash coal make up for the shortage of reducing agent.

Chemical Conditions in Clay-Rocks

2015
Abstract Until the end of the 1990s, deep geological clay formations had no direct industrial applications and little research had been conducted to characterize the chemistry of pore-water in indurated clay-rocks. The emergence of the concept of radioactive waste disposal in clay-rock formations led to a research boom in this area.

Clay-bricks from recycled rock tailings

Ceramics International, 2016
Abstract The aim of this work is to optimize the industrial applications of granite and kaolinite rock tailings in ceramics industry. Three rock tailings are selected to be characterized and equally mixed for testing. The samples are characterized using XRD, XRF, polarizing light microscope, cathodoluminescence, X-ray micro-computed tomography (3 d ...

Fault slip in clay-rich rocks due to water-clay interactions

2023
Clay-rich rocks occur in a wide range of tectonic settings. They are of great interest, for example, for the mechanical properties of shallow subduction zone interfaces, but also for natural barriers in nuclear waste deposits or as subsurface caprocks for CO2 storage.
