Halite thickness in Mbr 2 of the Kumugeliemu can reach 1000 m. The thick halite is associated with sedimentary rock with shallow water fabrics. The thick halite was formed in a shallow‐sea water environment. The ‘Multiple transgression‐salt‐forming’ model was established.

X-ray Amorphous Components of Antarctica Dry Valley Soils: Weathering Implications for Mars [PDF]
The Antarctic Dry Valleys (ADV) comprise the largest ice-free region of Antarctica. Precipitation usually occurs as snow, relative humidity is frequently low, and mean annual temperatures are about -20C [1]. Substantial work has focused on soil formation

Clay mineralogy and shale instability: an alternative conceptual analysis
The instability of shales in drilled formations leads to serious operational problems with major economic consequences for petroleum exploration and production.

Sedimentological and geochemical characteristics are used to reconstruct sedimentation dynamics and erosional processes. Several rapidly deposited layers are characterised over changing depositional environments during the Late Holocene, from a phase when the lake was connected to the sea to a more stable state conducive to varve formation.

Clay Minerals – Mineralogy and Phenomenon of Clay Swelling in Oil & Gas Industry
Among the minerals found in the earth's crust, clay minerals are of the widest interest. Due to the specific properties such as plasticity, absorbing and catalytic properties clay minerals are used in many industries (oil & gas, chemistry, pharmacy ...

A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

Mineralogical characterisation and processing of some industrial minerals from Uganda [PDF]
This report describes the mineralogical characterisation and processing of several industrial minerals collected by Dr DJ Morgan in October 1991 during a visit to Uganda (Visit report WG/91/31R).
