Formation of Ultra‐Depleted Mantle Peridotites and Their Relationship With Boninitic Melts: An Example From the Kamuikotan Unit, Hokkaido, Japan

Abstract

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,

CoDA-Based Geo-Electrochemical Prospecting Prediction of Uranium Orebodies in Changjiang Area, Guangdong Province, China

“…This method represents Aitchison's space data in a logarithmic ratio coordinate system and transforms it into Euclidean space in order to overcome the closure effect of compositional data, making it possible to analyze the data using multivariate statistical methods [17]. This method has been proven effective in numerous research examples [18][19][20][21][22][23][24][25][26][27][28][29]. Scholars generally believe that data transformed by this method can better reflect the true distribution patterns of data in space, accurately identifying the background and anomalous information of elements.…”
