The natural removal of carbon dioxide and its permanent storage by the Earth system occurs
through (i) inorganic carbon and (ii) organic carbon pathways. The former involves the …

It is important for the study of palaeo-oceanography and palaeoclimatology to estimate the
primary productivity in surface water and redox conditions in water columns. The study of …

海洋表层初级生产力大小以及水体氧化还原条件是古海洋和古气候研究的重要内容,
而元素地球化学是研究初级生产力以及氧化还原条件最常用的手段. 主量元素Fe 和Si …

Tight-gas and shale-gas systems can undergo significant depressurization during basin
uplift and erosion of overburden due primarily to the natural leakage of hydrocarbon fluids …

Identification of methane sources controlling hydrate distribution and concentrations in
continental margins remains a major challenge in gas hydrate research. Lack of deep fluid …

Subduction zones serve as carbon recycling centers, where vast amassments of geologic
carbon accrete or subduct through thermogenic gas windows over millions of years. We …

We present an integrated 2D model of thermal and microbial generation of methane,
migration into the gas hydrate stability zone (HSZ), and formation of methane hydrates. The …

Rising ocean temperatures and falling sea level are commonly cited as mechanisms of
marine gas hydrate destabilization. More recently, uplift—both isostatic and tectonic—has …

The oxidation of hydrocarbons, including methane, is part of interrelated hydrogeochemical
reactions affecting the carbon budget in Earth's crust. To investigate these processes in …

We present a three‐dimensional gas hydrate systems model of the southern Hikurangi
subduction margin in eastern New Zealand. The model integrates thermal and microbial gas …
