(Table T1) Radioelement concentration and radiogenic heat production of ODP Holes 173-1067A and 173-1068A@en

Mean values of radiogenic heat production are derived from measurements of radioelements on the following rock types: amphibolite (0.358 ± 0.118 µW/m**3) and tonalite gneiss (0.802 ± 0.039 µW/m**3) at Site 1067 and serpentinized peridotite (0.0108 ± 0.0003 µW/m**3) at Site 1068. The results for serpentinized peridotite and amphibolite are consistent with previous measurements on samples from Sites 897 and 900. These results suggest that the thin continental crust in this region would contribute very little to the conductive heat flow.放射性生热率的平均值基于以下岩类中放射性元素的测量结果推导得出：1067站位的角闪岩（amphibolite）为(0.358 ± 0.118 µW/m³)、英云闪长片麻岩（tonalite gneiss）为(0.802 ± 0.039 µW/m³)，以及1068站位的蛇纹石化橄榄岩（serpentinized peridotite）为(0.0108 ± 0.0003 µW/m³)。蛇纹石化橄榄岩与角闪岩的测量结果与此前897、900站位样品的检测数据相一致。上述结果表明，该区域的薄型大陆地壳对传导热流的贡献极小。
