Evidence in the Japan Sea of microdolomite mineralization within gas hydrate microbiomes
Abstract Over the past 15 years, massive gas hydrate deposits have been studied extensively in Joetsu Basin, Japan Sea, where they are associated primarily with active gas chimney structures. Our research documents the discovery of spheroidal microdolomite aggregates found in association with other...
