Mapping Listvenite Occurrences in the Damage Zones of Northern Victoria Land, Antarctica Using ASTER Satellite Remote Sensing Data

Remote Sensing, 2019
Listvenites normally form during hydrothermal/metasomatic alteration of mafic and ultramafic rocks and represent a key indicator for the occurrence of ore mineralizations in orogenic systems.

PRECIOUS-METAL MINERALIZATION AT THE WESTERN EXOCONTACT OF THE HAUTAVAARA MASSIF, SOUTH KARELIA

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017
Intense silicification zones and metasomatic alterations (propylitic-type) with Au-Bi-Tebearing base-metal and sulfoarsenide mineralization were revealed at the exocontact of the Hautavaara granosyenite-monzogranite massif, South Karelia.

Experimental metasomatic alteration of titanite in a series of metamorphic fluids at 700 °C and 200 MPa [PDF]

Mineralogy and Petrology
AbstractSeven experiments exploring the reaction of titanite with various hydrothermal solutions have been carried out at 700 °C and 200 MPa for a run duration of 16 days. In experiments involving fluids consisting of NaCl+H2O, KCl+H2O, CaCl2+H2O, 2M NaOH, or 2M KOH, no reaction of the titanite with the fluid was observed other than a slight ...
