为了进一步理解碳酸盐和硅酸盐的角色,在调整空气/土壤公司摇<潜水艇class=“ a-plus-plus ”> 2 水平,公司的流动<潜水艇class=“ a-plus-plus ”>硅酸盐和碳酸盐岩石捱过的化学药品消费的 2 在土壤侧面从元素的变化被决定。结果证明碳酸盐岩石捱过的化学药品主要发生在岩石表土接口,并且在碳酸盐岩石上的 residua 土壤的进一步的捱过类似于花岗石侧面的。硅酸盐岩石的化学捱过通过整个侧面发生了。因此,公司<潜水艇class=“ a-plus-plus ”>硅酸盐每体积消费的 2 介绍[ M <潜水艇class=“ a-plus-plus ”> sr (公司<潜水艇class=“ a-plus-plus ”>碳酸盐上的 2 )]和残余摇[ M <潜水艇class=“ a-plus-plus ”> cr (公司<潜水艇class=“ a-plus-plus ”> 2 )]基于元素的捱过坡度被计算。公司 < 潜水艇 class= “ a-plus-plus ” > 2 由碳酸盐 protolith 消费了[M < 潜水艇 class= “ a-plus-plus ” > cp (CO 2 )] 在岩石表土接口从元素的变化被计算。M < 潜水艇 class= “ a-plus-plus ” > sr ( 公司 < 潜水艇 class= “ a-plus-plus ” > 2 ) 是大约十~千比 M 大数量级 < 潜水艇 class= “ a-plus-plus ” > cr ( 公司 < 潜水艇 class= “ a-plus-plus ” > 2 ) 。甚至这样,这证明碳酸盐岩石上的残余能是公司的一个水池 < 潜水艇 class= “ a-plus-plus ” > 长期的规模上的 2 。 M <潜水艇class=“ a-plus-plus ”> cp (公司<潜水艇class=“ a-plus-plus ”> 2 )比 M 大大约四倍<潜水艇class=“ a-plus-plus ”> sr (公司<潜水艇class=“ a-plus-plus ”>证明碳酸盐摇的 2 ),玩了一在调整 CO 的更重要的角色<潜水艇class=“ a-plus-plus ”>比硅酸盐,岩石在侧面的 pedogenic 过程期间做了的 2 水平。
To further understand the roles of carbonate and silicate rocks in regulating the atmosphere/soil CO2level,the flux of CO2 consumed by the chemical weathering of silicate and carbonate rocks was determined from the elemental change in soil profiles.Results showed that the chemical weathering of carbonate rocks mainly occurred at the rock-regolith interface,and that the further weathering of the residua soil on the carbonate rocks was similar to that of the granite profile.Chemical weathering of the silicate rocks occurred through the whole profiles.Therefore,CO2 consumed per volume by the silicate profiles[M(sr)(CO2)]and the residues on carbonate rocks[M(cr)(CO2)]were calculated based on the elemental weathering gradients.CO2 consumed by carbonate protolith[M(cp)(CO2)]was calculated from the elemental change at the rock-regolith interface.The M(sr)(CO2) were about tens to thousands orders of magnitude greater than M(cr)(CO2).Even so,this demonstrated that the residues on carbonate rocks could be a sink of CO2 on long-term scales.The M(cp)(CO2) was about four times larger than M(sr)(CO2),which demonstrated that carbonate rocks played a more important role in regulating the CO2 level than the silicate rocks did during the pedogenic process of the profiles.
