... setting unrelated to subduction. The Anjishan adakitic intrusive rocks, which are exposed in the Ningzhen area of east China, have high Sr/Y and La/Yb ratios coupled with low Yb and Y as well as relatively high MgO contents and Mg numbers (Mg#; 0.4–0.6), similar to products from slab melting. However, low...

The triangles denote the permanent stations deployed by China Digital Seismological Network. (b) Installation of the sensor. A flat marble board is fixed horizontally at the bottom of an excavation (the depth of the excavation is about 100 cm) using fast concrete mix. The sensor is then placed on this marble inside this excavation, with its horizontal components oriented north–south. The excavation is protected by a large, 50  cm×50  cm box without a base panel, which allows the closing of the geophone space and is used to thermally isolate the sensor.
