Abstract

Seperate of deformation stages, deformation phases and reconstracted their strees fields at Cuu Long basin is very important for explore oil/gas. Based on analysis and synthesis of geological data and geophysical data, it showing that the Cuu Long basin exists four major deformation stages: 

-    Early-Middle Jurassic Post Collisional Orogenic Stage (D1)

-    Late Jurassic-Cretaceous Active Continental Triệu nămrgin stage (D2)

-    Eocene-Early Miocene Rifting stage (D3) includes six deformation phases:  D3.1, D3.2, D3.3, D3.4, D3.5 and D3.6. Phases of D3.1, D3.3 và D3.5 are extention and thermal subsidence formed basin. Phases of D3.2, D3.4 and D3.6 are compression formed folds, faults and fractures

-    Late Early Miocene – Quaternary shelf of passive continental margin stage (D4)
