toàn biến chất
Definition
- Adjective:
- Paramorphic / Paramorphous: In geology and mineralogy, describes a mineral or rock that has undergone complete paramorphism. This means its chemical composition remains unchanged, but its internal crystal structure has been entirely transformed into a different, more stable structure under new physical conditions (e.g., temperature, pressure).
Usage Examples
- Adjective:
- Thạch anh có thể tồn tại ở dạng toàn biến chất từ một dạng tinh thể khác. (Quartz can exist in a paramorphic form from a different crystal structure.)
- Các nhà địa chất nghiên cứu các mẫu vật toàn biến chất để hiểu lịch sử nhiệt động của khu vực. (Geologists study paramorphic specimens to understand the thermodynamic history of the region.)
Advanced Usage
- "Đá toàn biến chất": paramorphic rock.
- Bộ sưu tập này có một mẫu đá toàn biến chất hiếm. (This collection contains a rare sample of paramorphic rock.)
Variants and Related Words
- Biến chất (adj/n): metamorphic. Refers to the general process of metamorphism where rocks are altered by heat and pressure.
- Cấu trúc toàn biến chất (n): paramorphic structure.
Synonyms
- Paramorphous: Having completely changed form (in a mineralogical context).
- Structurally altered: Changed in internal structure without chemical change.
Related Scientific Terms
- Pseudomorph: A mineral that has the external crystal shape of another mineral species. Paramorphism is a specific type of pseudomorphism where the change is complete and structural.
- Polymorph: One of two or more different mineral species with the same chemical composition but different crystal structures (e.g., diamond and graphite). A paramorph is a transformation from one polymorph to another.
