The Vietnamese word "đá phiến" refers to a type of rock known as "schist" in English. Here’s a breakdown to help you understand it better:

Definition:

• Đá phiến (Schist): A metamorphic rock that is characterized by its layered structure and the presence of larger crystals within a finer-grained matrix. Schist is formed from the alteration of shale or other sedimentary rocks under heat and pressure.

Usage Instructions:

• "Đá phiến" is commonly used in geology to describe this specific type of rock. You might encounter it in discussions about earth sciences, construction, or landscaping.

Example Sentence:

• "Đá phiến thường được sử dụng trong xây dựng vì tính bền vững của nó." (Schist is often used in construction because of its durability.)

Advanced Usage:

• In geology, "đá phiến" can be classified further based on its mineral composition (e.g., mica schist, garnet schist). When discussing it in a scientific context, it's helpful to specify these types.

Word Variants:

• Đá: This means "rock" in Vietnamese, which can be used in many other contexts.
• Phiến: This means "slab" or "layer," indicating the layered nature of the rock.

Different Meanings:

• While "đá phiến" primarily refers to schist, the word "đá" can refer to any type of rock, and "phiến" can refer to any slab-like object. Thus, "phiến" on its own might refer to tiles or slabs made from various materials.

Synonyms:

• Đá biến chất: This means "metamorphic rock" and includes schist along with other types of rocks formed under heat and pressure.

Related Terms:

• Đá trầm tích: This means "sedimentary rock," which is the type of rock that schist can originate from.
• Đá magma: This means "igneous rock," another type of rock in the rock cycle.
