华北西北部狼山二辉橄榄岩包体的矿物含量、化学组成及温压估算数据集

本数据为地幔橄榄岩矿物含量估计、矿物主微量元素组成数据以及橄榄岩的温度压力估算数据。样品为2019年采自华北克拉通西北部狼山地区玄武岩中的二辉橄榄岩。橄榄岩矿物含量估计利用双目显微镜完成。矿物主量元素和微量元素数据都通过激光剥蚀-电感耦合等离子体质谱仪分析得到。橄榄岩温度压力估算数据根据矿物温压计计算得到。通过获得的数据，可以揭示华北西北部岩石圈地幔性质及交代过程，为华北西北部岩石圈性质转变及构造体制转折提供证据。

This dataset comprises estimates of mineral abundances in mantle peridotites, major and trace element compositions of minerals, and calculated pressure-temperature (P-T) data for the peridotites. All samples are lherzolites hosted in basalts collected from the Langshan area, northwestern North China Craton, in 2019. Mineral abundances of the peridotites were estimated using a binocular microscope. Major and trace element compositions of the minerals were analyzed via Laser Ablation-Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). The P-T estimates for the peridotites were calculated using mineral geothermobarometers. The acquired data can reveal the nature of the lithospheric mantle and metasomatic processes in northwestern North China, providing evidence for lithospheric property transitions and tectonic regime shifts in this region.
