I'm not answerable to you for my every movement.

我无须为每一个动出交代。

Electronmicroscopic examination shows that Ti-oxide (rutile or anatase) is replaced by brannerite, indicat-ing the metasomatic origin of brannerite.

在电镜下观察到钛铀矿与钛的氧化（金红石或锐钛矿）成交代关系，说明钛铀矿是交代成因的。

The types of deposits basically are differential metasomatism in the later magma, pneumatolytic hydrothermal process, pegmatite process, residual deposits and placer deposits.

矿床类型以岩浆晚期分异交代型、气成热液型、伟岩型、风化壳型和砂矿型为主。

When metal-bearing solution moved along deep faults to cavities or frac tures, the metal cations reated with pyrite and organic matter and precipitated as sulfid...

在构造减压中，铅锌配合物交代地层中的黄铁矿或被有机质还原而沉淀富集。

There is an obvious rock zonation from the middle to bothsides of the structural shatter zone, generally from marialite orebody through diopside-felsite,biotite-albitite to the host Proterozoic rocks.

构造碎的岩石具有明显的对称分：碎的中心为钠柱石矿体，两侧依次为榍石透辉石长英岩、黑云母钠长岩，并逐渐过渡为围岩。钠柱石矿的成因类型为沿构造碎产出的热液交代脉型。
