Abstract:
This dataset reports in situ major elements of plagioclase of andesite from Kueishantao, north of Taiwan, China. Major element compositions of Pl were obtained with a JEOL JXA-8230 electron microprobe at Ocean University of China.
Keyword(s):

Comment:
Thermobarometry calculations of Pl were conducted using equation of Putirka (2008). The albite-anorthite exchange coefficient KD(Ab-An)pl-liq is used as a test for equilibrium, and has been experimentally determined to be 0.27 ± 0.11 for melt ≥ 1050 °C and 0.10 ± 0.05 for melt < 1050 °C (Putirka, 2008).
