Overlooked experimental evidence for K-replacements of plagioclase and origin of microcline in granite plutons [PDF]
, 2000 Experimental studies show that K replacement of Na in triclinic plagioclase under hydrothermal conditions results directly in triclinic microcline without forming intermediate monoclinic orthoclase.

Journal of Petroleum Geology, EarlyView.ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract NASA has led multispectral (≥3 wavelength bands) thermal infrared (TIR) sensor development from the earliest days of the agency. These data are critical in addressing a wide range of scientific questions and administration priories by measuring both temperature (for wildfire and volcanic eruption monitoring, agricultural plant stress, and ...

An intrusive-like tectonic breccia in the archipelago of southwestern Finland [PDF]
Bulletin of the Geological Society of Finland, 1986 On an islet in the archipelago of southwestern Finland with metamorphic rocks belonging to the Svecofennian zone it is possible to follow in exposure for a distance of some metres the transition from a layered paragneiss with amphibolite bands to a ...

Fossils as cultural heritage: Scientific, commercial and legislative issues
Geology Today, Volume 42, Issue 5, Page 263-272, September/October 2026.Fossils are among the principal sources for understanding the history of life through ‘Deep Time’ and can inform projections of biotic responses to environmental change. Despite a widespread recognition of the scientific, historical and communication significance of fossils in our culture, their role as part of our cultural heritage is still far from ...
