The diagenetic evolution of kaolin and illitic minerals in sandstones is described here. The
structural characterization of these minerals, the possible reaction pathways leading to their …

The kaolinite-group minerals kaolinite, dickite, nacrite, halloysite including its metaform and
their associates allophane and imogolite are phyllosilicates characterized by a rather simple …

The thick Eocene carbonate deposits that are newly ascribed as Radwany Formation
(previously Thebes Formation) in the October basin within the Gulf of Suez region, are of …

The spatial and temporal distribution of diagenetic alterations in siliciclastic sequences is
controlled by a complex array of interrelated parameters that prevail during eodiagenesis …

ABSTRACT Five Lower to Middle Jurassic sandstone reservoirs from the Norwegian sector
provide examples of deep porosity preservation caused by grain-coating, authigenic …

Dissolution of feldspar and mica and precipitation of kaolinite require a through flow of
meteoric water to remove cations such as Na+ and K+ and silica. Compaction driven pore …

Presently available techniques for predicting quantitative reservoir quality typically are
limited in applicability to specific geographic areas or lithostratigraphic units, or require input …

It is our pleasure to present this large body of information and thoughts of many mineral
scientists which has accumulated over decades. Illite is a mineral that has been discovered …

Replacement of kaolinite by dickite has been observed to occur with increasing depth of
burial in sandstones from three different basins on the Norwegian continental shelf. In the …
