Modal mineralogy for pyroxenite and chromitite samples from the MG1 chromitite layer in the Bushveld Complex, South Africa

Modal mineralogy for chromitite and pyroxenite samples from the Bushveld Complex. These come from drill core ZK135 collected in the Thaba mine located in the northwestern part of the Bushveld. The drill core intercepts the MG1 chromitite layer, which is bounded at the top and bottom by orthopyroxenite cumulate rocks.

布什维尔德杂岩（Bushveld Complex）中铬铁矿岩（chromitite）与辉石岩（pyroxenite）样品的模态矿物学数据集。该批样品采自位于布什维尔德西北部的塔巴矿（Thaba mine）的ZK135钻孔岩心。此钻孔岩心揭露了MG1铬铁矿层，其顶、底界面均被斜方辉石岩堆积岩（orthopyroxenite cumulate rocks）所围限。
