Data for: Geochemistry, petrogenesis, zircon U-Pb geochronology and Sr-Nd isotopic composition of Kuh-e-Shah volcanic rocks: Implications for an active continental margin along with eastern Iran during the Paleogene

In this study, we present new geochemical (whole-rock major and trace element), isotopic (Rb-Sr and Sm-Nd) and geochronological (U-Pb) data from the Kuh-e-Shah volcanic rocks with a comparison to other scattered volcanic rocks throughout the Lut Block (Pang et al., 2013; Saadat & Stern, 2016; Javidi Moghaddam et al., 2019) in order to better understanding the Paleogene magmatism evolution of the Lut Block and to place constraints to the timing and onset of volcanism, its tectonic implications, the geochemical features of the mantle source involved in volcanic rocks genesis, petrogenetic processes and the controls of magma generation processes, the probable effects of fractional crystallization and crustal contamination, and geodynamic evolution of volcanic rocks which exposed in the western part of the Kuh-e-Shah volcano-plutonic complex.

本研究报道了库赫沙赫（Kuh-e-Shah）火山岩的全新地球化学数据（全岩主量与微量元素数据）、Rb-Sr与Sm-Nd同位素数据，以及U-Pb地质年代学数据，并与卢特地块（Lut Block）内已发表的其他零散分布火山岩开展对比（Pang等，2013；Saadat & Stern，2016；Javidi Moghaddam等，2019）。本研究旨在深入解析卢特地块古近纪岩浆作用的演化历程，约束火山作用的发生时限与起始节点，阐明其构造指示意义、火山岩成因所涉及的幔源地球化学特征、岩石成因过程与岩浆生成作用的控制机制、结晶分异与地壳混染的潜在影响，以及库赫沙赫火山-侵入杂岩体西部出露火山岩的地球动力学演化规律。
