“…Because these peridotites lack clinopyroxene, which is generally the main budget of incompatible trace elements in peridotites, it is difficult to obtain their mineral trace elements compositions. However, recent studies show that trace element compositions of olivine and orthopyroxene do in fact record the formation and later metasomatic/metamorphic processes (e.g., Demouchy & Alard, 2021; Jean & Shervais, 2017; Nishio et al., 2022a; Scott et al., 2016). In this study, we examine olivine and orthopyroxene trace element compositions in addition to the petrography and mineral major element compositions from one of the clinopyroxene‐free ultra‐depleted peridotite bodies from the Kamuikotan unit.…”

Ultra-depleted peridotites, which refer to peridotites that have undergone high degrees of partial melting, are an important end-member component of Earth's mantle (e.g., Xu et al., 2021). Due to their refractory physiochemical characteristics, ultra-depleted peridotites have the potential to contribute to continent stabilization (Scott et al., 2019), lithospheric mantle processes during subduction initiation (Parkinson & Pearce, 1998) and craton formation (Pearson et al., 2021). The formation of ultra-depleted peridotites may play an important role in oceanic crust formation during the early stages of the subduction zone development. However, this mechanistic link between subduction initiation has mainly been reconstructed by studies on volcanic rocks, that is,

Effective forecasting of energy consumption structure is vital for China to reach its “dual carbon” objective. However, little attention has been paid to existing studies on the holistic nature and internal properties of energy consumption structure. Therefore, this paper incorporates the theory of compositional data into the study of energy consumption structure, which not only takes into account the specificity of the internal features of the structure, but also digs deeper into the relative information. Meanwhile, based on the minimization theory of squares of the Aitchison distance in the compositional data, a combined model based on the three single models, namely the metabolism grey model (MGM), back-propagation neural network (BPNN) model, and autoregressive integrated moving average (ARIMA) model, is structured in this paper. The forecast results of the energy consumption structure in 2023–2040 indicate that the future energy consumption structure of China will evolve towards a more diversified pattern, but the proportion of natural gas and non-fossil energy has yet to meet the policy goals set by the government. This paper not only suggests that compositional data from joint prediction models have a high applicability value in the energy sector, but also has some theoretical significance for adapting and improving the energy consumption structure in China.
