Analyses were carried out on both gas hydrate microdolomite inclusions and methane derived carbonates.Using the data, we were able to derive a model for radiogenic helium-4 production within the two types of carbonate and determine quantitative differences between gases trapped in seep-related carbonates from Joetsu Basin, offshore Niigata,and Tatar Trough in the northern part of Japan Sea. We also determined the stable isotopic composition of the carbonates to compare with that of the carbon dioxide in the inclusions. The mineralogy of the carbonates was determined through X-ray diffaction.At the Mobara seep sites of Chiba Prefecture microcrystalline carbonates were not recovered but were able to determine the noble gas and stable isotopic composition of the bubbling gases.

对天然气水合物微白云岩包裹体和甲烷碳酸盐岩进行了分析，得出了这两种碳酸盐岩中放射成因氦-4的生成模式，并确定了上越盆地、新泻近海和日本海北方塔塔尔海槽渗漏相关碳酸盐岩中所捕获气体的定量差异。我们还测定了包裹体中碳酸盐的稳定同位素组成，并与二氧化碳的稳定同位素组成进行了比较。在千叶县茂原渗漏现场，微晶碳酸盐没有被回收，但能够确定惰性气体和稳定同位素组成的起泡气体的碳酸盐的矿物学通过X射线衍射测定。
