Late Paleozoic crustal composition and growth in West Junggar: Evidence from Sr-Nd-Pb isotopic mapping

doi:10.13745/j.esf.sf.2022.2.8

Abstract

Abstract:

The West Junggar region has experienced intense Late Paleozoic magmatic activity, where vertical and lateral crustal accretion is significant and crustal growth and evolution is multi-stage. Focusing on Sr-Nd-Pb isotopic mapping, this study found that the West Junggar region has the isotopic characteristics of high positive ε_Nd(t) value of 2.29-8.75, low ( ⁸⁷Sr/⁸⁶Sr)_i ratio of 0.697397-0.708336, and (²⁰⁶Pb/²⁰⁴Pb)_i ratio of 17.4975-19.0352; it has a young crustal model age by calculation. The source area is dominated by Paleozoic new crust, with mantle contribution greater than 50%, and there is almost no old crystalline basement in the deep crust, which is in agreement with regional tectonic geological and geophysical data. The West Junggar region mainly experienced three orogenic stages in the Late Paleozoic: arc-dominated lateral growth in the Middle-Late Carboniferous; post-collision vertical growth in the Late Carboniferous-Early Permian; and vertical growth in the Early Permian-Triassic with crust-mantle mixed source. Regional orogenesis ends in the Early Triassic.
