Peridotite-melt interaction: a key point for the destruction of cratonic lithospheric mantle

Indo‐Asian Collision: Transition from Compression to Lateral Escape Tectonics

“…Since the North China craton experienced more complete removal, it has become a typical region for the studies of craton rejuvenation and delamination (Fan et al, 2000;Xu, 2001;Gao et al, 2004;Wu et al, 2006Wu et al, , 2008Menzies et al, 2007;Foley, 2008;Yang et al, 2008). It is important to understand the cause of the lithosphere destruction, the mechanism of the compositional transformation and the overall geodynamic environment (Zhang, 2009;Li et al, 2011). Since 2008, the Natural Science Foundation of China has launched a major research plan focusing on the major issues concerning the cratonic destruction in North China (Zheng & Wu, 2009).…”

“…During this process, the interactions of eclogite-derived melt with peridotites re-fertilized and undermined the cratonic lithospheric mantle (Gao et al, 2009;Li and Gerya, 2009). The destruction and thinning of the North China craton is the result of peridotite-melt interactions (addition of volatile) combined with enhanced regional thermal anomaly and lithospheric extension (Zhang, 2009). ancient basement complex reduce obviously (Fig.…”

Destruction of North China Craton: Insights from temporal and spatial evolution of the proto-basins and magmatism

“…There are obvious differences in the density of earth's spheres. For instance, the density of the lithosphere is 3.0 g/cm 3 , whereas that of the asthenosphere is 3.35 g/cm 3 [67]. Therefore, variation of lithosphere thickness can lead to variation of gravity gradient.…”

Adakitic rocks and destruction of the North China Craton: Evidence from experimental petrology and geochemistry

“…Essential information, such as the pattern, accurate timing and controlling factors of the dynamics for the destruction of the North China Craton have been discussed among Earth scientists, yielding different perspectives, including the potential for delamination [6][7][8][9][10][11][12][13][14][15][16][17][18][19], thermomechanical-chemical and subduction erosion [20][21][22][23][24][25][26][27][28][29][30][31][32][33], peridotite-melt reactions [34][35][36][37][38][39], and lithospheric mantle weakening by hydration [40]. A recent geophysical investigation [41], combined with petrology and geochemistry data, further demonstrate the main dynamic process for destruction of the North China Craton as follows: Subduction of the Mesozoic Pacific Plate caused the mantle underneath the eastern Asian continent to become unstable and flow faster.…”
