摘要:... Hydrothermal alteration is zoned outward and rarely extends for more than 15 m away from the vein walls; five alteration zones were defined: an adularia zone close to the veins, an intermediate halo characterized by illite and illite–smectite zones, and a distal smectite ...

摘要:... We identify volcanic areas in which the deformation is mainly related to the depressurization of the local hydrothermal systems, and recognize deformations along seismogenic and aseismic NNW–SSE and NW–SE faults. The deformations localized along the Southern Apennines ...

摘要:... Instead, hydrothermal-metasomatic events affected the sedimentary rocks in the study area, resulting in the depletion of alkaline earth elements and K metasomatism. Provenance modelling using REEs and trace element ratios indicate varying contributions from ultramafic to mafi...

摘要:采用沉积盆地构造—古地理位置恢复重建和构造—岩相学等新方法研究认为,凤太晚古生代沉积盆地属于受板块斜向俯冲碰撞动力学控制下的拉分盆地。在中泥盆世初期,凤太沉积盆地被周缘垂向基底隆起分隔,其成...
