碳酸盐

For a wide variety of lithologies from granite through gneiss, carbonate and amphibolite to basaltic rocks, it is shown that this relation is valid in the range 0～350 API and 0.03～7μW/m3 respectively with an error lower than 10%.

从片麻岩、碳酸盐岩、角闪岩、花岗岩到玄武岩，在这样宽的岩性变化范围内，显示出这种线性关系在0～350 API和0.03～7 μW/m3范围是有效的，其误差均小于10％。

On the contrary, some carbonate rocks with anhydrite do not contain H2S.

相反，与硬石膏的一些碳酸盐岩石不包含H2S。

IV. carbonate mineral contain iron, include siderite, ankerite, etc.

四、含铁碳酸盐矿物：有菱铁矿及铁白云石等。

IV. carbonate mineral contain iron granite and marble , include siderite, ankerite, etc.

四、含铁碳酸盐矿物：有菱铁矿及铁白云石等。

The carbonate cements, mainly consisting of ferroan calcite and ankerite, are telogenetic cements.

这样形成的碳酸盐胶结物为晚期胶结物，主要为含铁方解石和铁白云石。

Data obtained by thin-sections analysis, cathodoluminescence emission analysis and SEM/EDX show that carbonate cements seem to be the uppermost cements composed of ferroan sparry calcite and ankerite and are distributed mostly in the depth interval of 100 m below the unconformity, with their contents increasing with the depth.

通过薄片观察、阴极发光、扫描电镜/能谱分析，认为碳酸盐胶结物是研究区砂岩最主要的胶结物成分，其主要类型为方解石和铁白云石，垂向上含量随深度增加而增加，多集中分布在白垩系和侏罗系之间的不整合面之下约100 m的范围之内。

After superimposition of magmatic mineralization, chert-bearing water-rich carbonates, such as dolomite, ankerite and/or calcite were turned into serpentitite-talcite; greite and pyrite into pyrrhotite.

经过岩浆叠加改造，底部的纹层状含燧石富水高镁碳酸盐岩变为蛇纹石岩；胶黄铁矿、黄铁矿大部分变为磁黄铁矿。

The paragenetic sequence of outcrop sandstones may induce to ealy compaction diagenetic facies、carbonate cementation diagenetic facies and feldspar dissolving diagenetic facies, the diagenetic facies of core sandstones are ealy compaction diagenetic facies、ankerite diagenetic facies、authigenetic quarze and kaolinite filling diagenetic facies.

露头砂岩的成岩组合可归纳为早期压实成岩相、碳酸盐胶结成岩相和长石溶解成岩相，岩芯砂岩成岩相为早期压实成岩相、铁白云石胶结成岩相、自生石英与高岭石充填成岩相。

With the wet and dry air is not working, do not dissolve in acid, and even aqua regia does not dissolve, only soluble in molten alkali, ground and carbonates such as sodium oxide.

与干湿空气都不起作用，不溶于酸，甚至王水都不溶，仅溶于熔融的强碱、地氧化钠和碳酸盐等。

C This SEM image of the cement illustrates that it is composed of acicular aragonite.

希望能通过照片这种直观的方式让大家更进一步的了解这些特殊的碳酸盐岩样品。
