郭正府等-NC: 印度-亚洲大陆碰撞导致新生代大气CO2浓度变化（图）
郭正府 新生代 大气 CO2浓度
2021/6/30
新生代以来全球气候变冷是地球科学领域广泛关注的焦点问题之一，被认为与大气CO2浓度降低有密切的联系。青藏高原隆升及其相关的深部-表层相互作用在新生代气候转型过程中起着重要的作用，然而关于印度与亚洲大陆汇聚、碰撞、俯冲过程与新生代大气CO2浓度变化的具体作用机制仍存在很大的争议。一种观点认为，青藏高原隆升导致地表硅酸盐风化作用增强，加速消耗大气圈中的CO2，从而造成大气圈CO2浓度降低；另一种观点认...
Dynamics of fluid and heat flow in a CO2-based injection-production geothermal system
Binary system CO2-water displacement Heterogeneity Preferential flow

CO2 is now considered as a novel heat transmission fluid to extract geothermal energy. It can be used for both energy exploitation and CO2 geological sequestration. Here, a 3-D, “two-spot” pattern wel...
Tunable diode laser measurements of hydrothermal/volcanic CO2 and implications for the global CO2 budget

2015/1/6
Quantifying the CO2 flux sustained by low-temperature fumarolic fields in hydrothermal/volcanic environments has remained a challenge, to date. Here, we explored the potential of a commercial infrared...
First observational evidence for the CO2-driven origin of Stromboli's major explosions
CO2-driven origin Stromboli's major explosions
2014/12/31
We report on the first detection of CO2 flux precursors of the till now unforecastable "major" explosions that intermittently occur at Stromboli volcano (Italy). An automated survey of the crater plum...
