內容簡介
新英格蘭造山帶位於東澳造山帶*東部，包括新南威爾斯州大部分地區和昆士蘭州南部Texas地塊，其中黑斯廷斯地塊位於新英格蘭造山帶南部，受二疊紀以前構造變形的強烈改造，可劃分為北黑斯廷斯地塊和南黑斯廷斯地塊兩部分。《Unravelling the Deformation History of the Northern Hastings Block, Southern New England Orogen》通過研究區斷裂構造運動學分析，結合重力和磁力蠕蟲等模擬分析，重點研究了北黑斯廷斯地塊內斷裂系統的組成和活動期次，並詳細討論了其地質構造變形的演化過程。研究認為，北黑斯廷斯地塊內共有5期斷裂活動，其中兩期主要的斷裂系統與石炭紀早期北黑斯廷斯地塊的滑移與旋轉有關，個別右旋走滑斷裂系統則形成於較晚的晚三疊世。北黑斯廷斯地塊斷裂系統的運動學解析為該區金屬礦床的勘探與預測提供了重要的基礎地質信息。
