AbstractGranulite in eastern Shandong is mainly exposed in Laixi, Pingdu, Changyi and Anqiu, and the diagnostic mineral assemblage is Opx+Cpx+Hb+Pl ± Q ± Sea. The appearance of orthopyroxene and its coexistence with hornblende indicate that the reaction Hb+Q = Opx+Cpx+Pl+H2O did not proceed completely and therefore these rocks belong to the amphibolite‐ granulite transition facies, i.e., belonging to hornblende‐granulite subfacies. According to the data obtained from such geothermometers and geobarometers as Opx‐ Cpx, Opx‐ Hb, Cpx‐ Hb, Hb‐ PI, Sca‐ Pl and Fe‐ Ti oxides, it has been determined that the temperature of the main metamorphic stage was 720° – 810°C, the pressure 0.5 GPa and fo210−15.5, showing a geothermal gradient of 41–46°C / km, and thus the rocks belong to “low‐temperature” a
