Geochronology and Geochemistry of the Karadaban Bimodal Volcanic Rocks in the Altyn Area, Xinjiang: Implications for the Tectonic Evolution of the Altyn Ocean

<div>Chemical classification diagrams for the felsic volcanic rocks in the North Altyn Tagh region. (a) Ga/Al vs. Zr diagram (after [<a href="/journals/geofluids/2019/6256398/#B110">110</a>]) where all data fall into the A-type granite and (b) the Yb/Ta vs. Y/Nb diagram (after [<a href="/journals/geofluids/2019/6256398/#B102">102</a>]) exhibiting similarities to average crustal ratios between OIB (ocean island basalt) and IAB (island-arc basalt). Data of the Hongliugou granite are from [<a href="/journals/geofluids/2019/6256398/#B57">57</a>], Highland 4337 granodiorite are from [<a href="/journals/geofluids/2019/6256398/#B32">32</a>], and south Kaladawan granite are from [<a href="/journals/geofluids/2019/6256398/#B46">46</a>].</div>
