Mg-minerals of recent hydrothermal formations of the Cu-porphyric mineralisation at Recsk, Hungary
A great variety of minerals precipitated from thermal waters (35—44 °C) were observed in the drifts of the copper-porphyritic skarn ore deposit at Recsk. Beside calcite-aragonite and various salts with different solubility, the Mg-minerals (nesquehonite—dypingite—hydromagnesite—giorgiositenorthupite...

| Tartalmi kivonat: | A great variety of minerals precipitated from thermal waters (35—44 °C) were observed in the drifts of the copper-porphyritic skarn ore deposit at Recsk. Beside calcite-aragonite and various salts with different solubility, the Mg-minerals (nesquehonite—dypingite—hydromagnesite—giorgiositenorthupite—astrakhanite— /vanthoffite; langbeinite/ —epsomite—palygorskite) have outstanding importance at this locality. The present work focussea on the study and interpretation of the hydrothermal formation of the Mg-minerals otherwise known as hypergenitic evaporites. AUSZUG : In den Stollen des porohyrischen-skarn Cu-Erzlagers in Recsk ist eine ausserordentlich grosse Variation von hydrothermalen (35—44 °C) Mineralienabsonderungen vorhanden. Unter den KalzitAragonit-, und anderen Mineralsalzen von veränderlicher Lösbarkeit spielen die Magnesiumminerale (Nesquehonit—Dypingit—Hydromagnesit—Giorgiosit—Northupit—Astrakhanit— /Vanthoffit; Langbeinit/— Epsomit—Palygorskit) eine beachtliche Rolle. In dieser Arbeit wird die hydrothermale Entstehung dieser, von anderen Lokalitäten meistens als hypergen-evaporitischen Phasen beschriebenen Mg-Mineralien untersucht und erklärt. |
