Oxygenation of Earth’s atmosphere and oceans played a pivotal role in the evolution of the surface environment and life. It is thought that the rise in oxygen over Earth’s history was driven by an increasing availability of the photosynthetic limiting

This paper reports the latest whole-rock elemental contents (including platinum group elements; PGE), and the Cu isotopic composition of lower continental crustal rocks from different tectonic settings (Fig. 1). What they have in common is the proliferation of porphyry deposits, but they differ in...
The ophiolitic section forms a tectonic slab, made up primarily of mantle peridotites with minor crustal cumulates and mafic dikes. The mantle rocks constitute ~93% of the exposure section and include harzburgite and less dunite. Both the drill core and surface samples indicate that the ...
The future tsunamigenic potential of the Makran subduction zone remains uncertain due to its low and strange offshore seismicity (see Figure 1). In addition, some seismotectonic characteristics of the Makran subduction zone, such as the offshore seismicity, width and dip of the slab, ...

Then, we applied a direct surface wave tomographic method for the measured phase velocity dispersion data to obtain a 3D S-wave velocity model of the Kinki region. The estimated velocity model reveals a NE–SW trending low-velocity structure coinciding with the Niigata–Kobe Tectonic Zone (NKTZ...
