Near Surface Geophysics, Volume 20, Issue 6, Page 637-660, December 2022., 2022 ABSTRACT In mineral exploration, reliable and comprehensive petrophysical groundwork helps evaluate the success rate of applying geophysical methods to the target and thus improves the quality of decision‐making related to geophysical surveys. Petrophysical data for potential field exploration can be efficiently collected from drill cores together with

Boletín Geológico, 2020 The products of metasomatic alteration (e.g., carbonation) of peridotites are called listvenites. Based on a description of the outcrops in the laterite deposit at Cerro Matoso located in the NW of Colombia, the mineralogical composition confirmed by ...

Zircon survival in shallow asthenosphere and deep lithosphere [PDF]
American Mineralogist 2020 volume 105 pages 1662 to 1671, 2020 Zircon is the most frequently used mineral for dating terrestrial and extraterrestrial rocks. However, the system of zircon in mafic/ultramafic melts has been rarely explored experimentally and most existing models based on the felsic, intermediate and/or synthetic systems are probably not applicable for prediction of zircon survival in terrestrial ...

Melt-Enhanced Rejuvenation of Lithospheric Mantle: Insights from the Colorado Plateau [PDF]
(2016) J. Geophys. Res. Solid Earth, 121, 2012 The stability of the lithospheric mantle beneath the ancient cratonic cores of continents is primarily a function of chemical modification during the process of melt extraction. Processes by which stable continental lithosphere may be destabilized are not well-understood, although destabilization by thickening and removal of negatively-buoyant ...

ONTOGENETIC APPROACH TO THE METASOMATISM THEORY [PDF]
Минералогия, 2016 Metasomatism is a phenomenon of substitution of some minerals by other minerals under simultaneous dissolution of early minerals and crystallization of late minerals.
