纯硅质软泥──早期隧石形成的成岩环境Ｇ．Ｂｏｈｒｍａｎｎ等生物硅质沉积物转变成瓷状岩和燧石，其成岩途径是从蛋白石－Ａ变为蛋白石－ＣＴ，最后变为石英。因为矿物相的反应率很低，所以这个反应序列被认为在现代深海沉积条件下要几千万年才能完成。因此，隧石或瓷状...
Pure siliceous mud - the diagenetic environment G formed by early tunnels. Biogenic siliceous sediments such as Bohrmann transform into porcelain and chert, diagenetic pathways change from opal-A to opal-CT, and finally to quartz. Because of the low reaction rate of the mineral phase, this reaction sequence is thought to take tens of millions of years to complete in modern deep sea sedimentary conditions. Therefore, the tunnel or porcelain ...
