Clay mineralogy: A signature of granitic geothermal reservoirs of the central upper Rhine Graben
(MDPI, 2021)
Clay minerals are the signature of hydrothermal alterations related to fluid circulation in
volcanic and crystalline rocks. In the French part of the Upper Rhine Graben, in the deep-seated
granites, illitic minerals ...
SEM and TEM evidence of mixed-layer illite-smectite formed by dissolution crystallization processes in continental Paleogene sequences in northwestern Argentina
(Mineralogical Soc, 2018-01)
In the northernmost Calchaquí Valley (Salta, Argentina), the Paleogene continental sediments show a transition from smectite, at the top, to R3 I-S (>90% illite) through R1 I-S (65–80% illite), in contrast to the remaining ...
Calcined illite-chlorite shale as supplementary cementing material: Thermal treatment, grinding, color and pozzolanic activity
(Elsevier Science, 2019-10)
The thermal transformation (100–1100 °C) of two shales containing illite-chlorite (I/Ch), feldspars and quartz from La Cabañita quarry (Olavarria, Argentine) was studied by TG-DTA, XRD and FTIR. It included dehydration; ...
The tectonic significance of K/Ar illite fine-fraction ages from the San Luis Formation (Eastern Sierras Pampeanas, Argentina)
(Springer, 2011-01)
The Sierra de San Luis forms the southern tip of the Eastern Sierras Pampeanas in central Argentina. Two narrow belts of low-grade phyllites and quartz arenites, i.e. the San Luis Formation, have accommodated part of the ...
