    Whole-rock geochemistry and crystal chemistry of apatite at intrusive suites of the Qeynarjeh-Angouran district (west of Zanjan): an approach to the identification of skarn-causati... by Afsoon Dastour, Ebrahim Tale Fazel, Ashraf Torkian

    Published 2024-10-01
    “…These intrusive suites with zircon saturation temperature (TZr) less than 900 °C and meta-aluminous to slightly peraluminous nature (A/CNK = 0.5-1.2) belong to the calc-alkaline series, which is evidence of I-type granitoids (Na2O/K2O = 0.8-2.0) in subduction zones (enrichment of LILE compared to HFSE along with P, Nb and Ti anomalies). …”

    Coseismic Deformation Responses due to Geometrical Structure and Heterogeneity of the Accretionary Wedge: Study Case 2010 Mentawai Earthquake, West Sumatra, Indonesia by Alvina K. Kuncoro, Wahyu Srigutomo, Umar Fauzi

    Published 2023-01-01
    “…The 2010 tsunami earthquake was located at the Mentawai segment, which is a part of the accretionary wedge in the Sumatra subduction zone. This active accretionary wedge is identified as the most complicated structure on earth and lies along the Sumatra subduction zone, at which most destructive earthquakes happen in this region. …”
