chromium isotopes of chromite in ophiolite

This is the first Cr isotope data for orthopyroxene, olivine and chromite in residual harzburgite, dunite and chromitite from the mantle-crust transition zone and upper mantle parts of the Kızıldağ ophiolite, SE Turkey.本数据集为首次报道的土耳其东南部基兹尔达格（Kızıldağ）蛇绿岩（Kızıldağ ophiolite）壳幔过渡带（mantle-crust transition zone）与上地幔（upper mantle）区域内，残留方辉橄榄岩（residual harzburgite）、纯橄榄岩（dunite）及铬铁岩（chromitite）中的斜方辉石（orthopyroxene）、橄榄石（olivine）与铬铁矿（chromite）的铬同位素数据。
