简介 | 内容推荐 新英格兰造山带位于东澳造山带最东部,包括新南威尔士州大部分地区和昆士兰州南部Texas地块,其中黑斯廷斯地块位于新英格兰造山带南部,受二叠纪以前构造变形的强烈改造,可划分为北黑斯廷斯地块和南黑斯廷斯地块两部分。本书通过研究区断裂构造运动学分析,结合重力和磁力蠕虫等模拟分析,重点研究了北黑斯廷斯地块内断裂系统的组成和活动期次,并详细讨论了其地质构造变形的演化过程。研究认为,北黑斯廷斯地块内共有5期断裂活动,其中两期主要的断裂系统与石炭纪早期北黑斯廷斯地块的滑移与旋转有关,个别右旋走滑断裂系统则形成于较晚的晚三叠世。北黑斯廷斯地块断裂系统的运动学解析为该区金属矿床的勘探与预测提供了重要的基础地质信息。 目录 Preface Foreword Chapter 1 Geological Background 1.1 Tectonic Setting 1.2 Local Setting 1.3 Structural History 1.3.1 Nambucca Block 1.3.2 Hastings Block 1.3.3 Port Macquarie Block 1.3.4 Tamworth Belt 1.4 The Hunter-Bowen Orogeny Chapter 2 Folding and Cleavage History in the NHB 2.1 Introduction 2.2 Methodology 2.3 Analysis of Bedding Data in the NHB 2.4 Analysis of Cleavage Data in the NHB 2.5 Analysis of Folding Data in the NHB 2.6 Evidence of Overprinting of Structures in the Nambucca Block and NHB 2.6.1 Evidence of Overprinting of Structures in the Nambucca Block 2.6.2 Cleavages in the NHB 2.6.3 Folded Folds in the NHB 2.6.4 Faults Displacing Cleaved and Folded Rock in the NHB 2.7 Evidence of Overprinting of Structures in the Nambucca Block and NHB Chapter 3 Fault History in the Northern Hastings Block, Southern New England Orogen 3.1 Previous Work 3.2 Conventional Fault Analysis 3.3 Kinematics and Morphology of Faults 3.4 Fault Timing 3.4.1 The Earliest Time Faulting Could Have Started 3.4.2 The Latest Time Faulting Could Have Stopped 3.4.3 The Relationship between Faulting and Folding/Cleavage Development 3.5 Fault Movement Analysis 3.5.1 The Earliest Time Faulting Could Have Started 3.5.2 The Latest Time Faulting Could Have Stopped 3.5.3 Faults with a Common Strike 3.5.4 Implication of Fault Movement Analysis 3.5.5 Fault History of the Northern Hastings Block 3.6 Brief Summary Chapter 4 Evidence from Fault Block Analysis for A Re-interpretation of the Northern Hastings Block Geology 4.1 Fault Systems in the NHB 4.2 Interpretations of Geological Data 4.3 Gravity and Magnetic Worms Analysis in the HB 4.3.1 Gravity and Magnetic Worms 4.3.2 Worms Analysis in the Hastings Block 4.4 Fault Block Analysis 4.4.1 Fault Block A 4.4.2 Fault Block B 4.4.3 Fault Block C 4.4.4 Fault Block D 4.4.5 Fault Block E 4.4.6 Fault Block F 4.4.7 Fault Block G 4.4.8 Fault Block H 4.4.9 Fault Block I 4.4.10 Fault Block J 4.4.11 Fault Block K 4.5 Implications 4.5.1 Fault Block Analysis Highlighted the Shortcomings with the Existing Geological Map 4.5.2 Implication of the Fault Blocks Reconstruction for the Entire NHB 4.6 Brief Summary Chapter 5 Geological History 5.1 Northern Hastings Block-Nambucca Block 5.2 Relationship to Surrounding Blocks References Appendices Appendix 1 Appendix 2 Appendix 3 |
