本文总结并报导了斯洛伐克西喀尔巴阡山脉内侧的石炭纪岩石中产出的菱镁矿和滑石成因的最新资料。这些矿床赋存于Veporicum构造超单元中和该超单元与Gemericum的接触带中。北部Sinec成矿带是主要的菱镁矿和滑石矿化区,产出的主要矿床有Kokava,Sinec,Samo,Hnst’a-Mutnik等矿床。而南部的Ochtina成矿带只产有菱镁矿床,主要矿床包括在Dubrava地体上的Dubrava,Mikova,Mikova,JedLovec;Lubenik,Ochtina,Kosice-Bankov,Banisko,Medvedia等矿床。 菱镁矿形成于变质M1期石炭系中方解石被白云石和菱镁矿连续交代过程(北矿带成矿温度为280~400℃,南矿带成矿温度为370~420℃;Radvanec & Prochaska,2001;Kodera & Radvanec,2002)。Permoscythian蒸发卤水提供了Mg。成矿事件和华力西期碰撞后运动有关。拉伸构造和高热流值促使成矿热液系统的产生。 滑石矿化则形成于稍晚的不同期变质事件(M2),成矿流体来源也与菱镁矿化不同。构造的、微构造的、变质的以及地质年代学的数据将滑石成矿作用和阿尔卑斯上白垩系的构造地热事件AD2联系在一起。AD2事件是阿尔卑斯碰撞(AD1)地壳加厚和变质核杂岩体起源的结果,体现在地壳不整合面上的区域拉伸,及开放系统中大规模热液流动。这一过程在更靠近Veporic热穹的北带区域(Sinec剪切带
This paper summarizes and reports on the latest information on the genesis of magnesite and talc from Carboniferous rocks inside the Western Carpathians, Slovakia. These deposits occur in the Veporicum tectonic unit and in the contact zone between the unit and Gemericum. The northern Sinec metallogenic belt is the main area for magnesite and talc mineralization. The major deposits produced are the Kokava, Sinec, Samo and Hnst’a-Mutnik deposits. In the southern Ochtina metallogenic belt, only magnesite deposits are produced. The major deposits include the Dubrava, Mikova, Mikova, Jedovec; Lubenik, Ochtina, Kosice-Bankov, Banisko and Medvedia deposits on the Dubrava land. Magnesite formed in metamorphic M1 carboniferous calcite was dolomite and magnesite continuous concretion process (mineralization temperature of 280 ~ 400 ℃ in the northern ore zone, the mineralization temperature of the South ore zone 370 ~ 420 ℃; Radvanec & Prochaska, 2001; Kodera & Radvanec, 2002). Permoscythian evaporation brine provides Mg. The ore-forming event is related to the post-collision movement in the Hurley period. Tensile structures and high heat flux values promote the formation of ore-forming hydrothermal systems. Talc mineralization was formed in later metamorphic events (M2), and the origin of ore-forming fluid was also different from magnesite mineralization. Tectonic, microtithetic, metamorphic, and geochronological data link talc mineralization with tectonic geothermal event AD2 in the Cretaceous in the Alps. The AD2 event is the result of the origin of the Alps collision (AD1) crustal thickening and metamorphic core complex, regional stretching on the unconformity of the crust, and large-scale hydrothermal flows in open systems. This process is in the northern zone closer to the Veporic thermal dome (Sinec shear zone
