Diagenetic neoformations in Middle Triassic evaporitic and carbonate rocks, Mecsek Mts. (S. Hungary)
In the Middle Triassic (Anisian) evaporitic and carbonate rocks of the Mecsek Mts. diagenetic neoformation of corrensite, Mg-rich chlorite, magnesite, albite and quartz has been observed by microscopic and X-ray diffraction methods. Fine-grained magnesite is found in clay mineral aggregates of silts...

| 520 | 3 | |a In the Middle Triassic (Anisian) evaporitic and carbonate rocks of the Mecsek Mts. diagenetic neoformation of corrensite, Mg-rich chlorite, magnesite, albite and quartz has been observed by microscopic and X-ray diffraction methods. Fine-grained magnesite is found in clay mineral aggregates of siltstones of detrital origin. Magnesites of very similar lithologic character have been found in the Drauzug area of the Eastern Alps and in Hesse, Germany, in a comparable stratigraphic position. Authigenic albites in limestones occur as euhearai crystals oriented according to (010). The formation of euhedral quartz of prismatic shape is accompanied by the formation of corrensite in carbonate rocks. The stability relations of these minerals are discussed in terms of thermodynamic considerations of LLPPMANN. The possible effects of Mg-enrichment in the solution and of transformation reactions of detrital expandable clay minerals are discussed. | |
