用法要点

名词用法

Schist 主要作为可数名词使用,指具体的片岩样本或类型,常用于地质学语境中描述岩石特性。

• a piece of schist
• various types of schist
• schist formations

介词搭配

常与介词 in、of、from 等连用,表示片岩的组成、来源或所处状态,如 in schist 表示在片岩中。

• rich in schist
• layers of schist
• extracted from schist

学术语域

Schist 属于专业地质学术语,日常对话中较少使用,多出现在科学报告、教材或专业讨论中。

• schist in geology
• schist metamorphism
• schist classification

基础例句

We found some interesting schist while hiking in the mountains.

我们在山里徒步时发现了一些有趣的片岩。

The garden path is made of local schist stones.

花园小径是用当地的片岩石块铺成的。

Can you tell the difference between schist and slate?

你能区分片岩和板岩吗?

This rock has layers that look like schist.

高级例句

The geological survey identified schist formations rich in mica minerals.

地质调查发现了富含云母矿物的片岩构造。

In metamorphic petrology, schist is classified by its foliated texture and mineral composition.

在变质岩石学中,片岩根据其叶理结构和矿物组成进行分类。

常见错误

❌ 错误:This is a schist rock.
✓ 正确:This is schist.

Schist 本身已表示片岩这种岩石,无需再加 rock,类似说 granite(花岗岩)而不说 granite rock。

❌ 错误:I saw many schists in the museum.
✓ 正确:I saw many pieces of schist in the museum.

Schist 作为物质名词通常不可数,指多块片岩时用 pieces of schist 或 schist samples,而非直接加复数。

近义词辨析

slate

Slate(板岩)也是变质岩,但颗粒更细,片理更明显且易裂成薄片,常用于屋顶材料;而 schist 颗粒较粗,片理不如板岩规则。

Slate is often used for roofing, whereas schist is more common in decorative stone.

gneiss

Gneiss(片麻岩)与 schist 同属变质岩,但 gneiss 具有条带状构造,矿物分带明显;schist 则以片状结构为主,矿物分布较均匀。

Gneiss shows banding of minerals, while schist has a more foliated appearance.
