为了研究单个火山内部和周围 3He/4He 比率分布的精细结构，在日本箱根火山火山口内的 13 个地点收集了喷气孔气体、地热气体和水。 3He/4He 和 4He/20Ne 比率分别为 6.7 × 10-6 至 9.6 × 10-6 和 0.85 至 26。火山口内样本的 3He/4He 比率（根据空气污染进行校正）是均匀的，并且与日本列岛岩浆液的比率一样高。火山口外部两个地热水样品的 3He/4He 比值明显低于火山口内部。观察到的 3He/4He 比率分布被解释为火山区域下方存在具有高 3He/4He 比率的源岩浆的指示。
To investigate a fine structure of the 3He/4He ratio distribution in and around a single volcano, fumarolic gases, geothermal gases and waters were collected at 13 sites within the caldera of the Hakone volcano, Japan. The 3He/4He and 4He/20Ne ratios vary from 6.7 × 10-6 to 9.6 × 10-6, and 0.85 to 26, respectively. The 3He/4He ratios, corrected for air contamination, of samples within the caldera are uniform and as high as those of magmatic fluids in the Japanese Islands. The 3He/4He ratios of two geothermal water samples outside the caldera are significantly lower than those of inside. The observed 3He/4He ratio distribution is interpreted as an indication of the presence of source magma with a high 3He/4He ratio beneath the volcanic region.
