L056 Seismic reflection and refraction survey in the Ooraminna area of the Amadeus Basin, NT, 1962 Images for traverse G, GX, GY, N, NX, NW

A seismic survey was made in the.Ooraminna area of the Amadus Basin 9 Northern Territory 9 by a seismic party of the Bureau of Mineral Resources 9 Geology and Geophysics 9 between 6th July and ,29th August 1962. Reflection traverses were recorded between Deep Well and Alice Springs andacross the culmination of the Ooraminna Anticline l and a refraction depth probe was recorded on the crest of the Ooraminna Anticline.The purpose of the survey was to obtain information on the structure of the Basin in the eastern part of the Missionary Plain, and on the structure of the Ooraminna. The Basin was shown to be generally synclinal between Deep Well and Alice Springs with a maximum sediment thickness Of 20,000 feet north of the Ooraminna Anticline. Seismic evidence suggested that the uplift at Deep Well and the Ooraminna Anticline have resulted from thickening in a deep formation, which has been tentatively identified as the Bitter Springs Formation.The survey was unsuccessful in relating reflectors in the crosssections with outcropping formations in the MacDonnell Ranges and on the Ooraminna Anticline.

1962年7月6日至8月29日，矿产资源地质和地球物理局（Bureau of Mineral Resources, Geology and Geophysics）的地震勘探队在北领地阿马杜斯盆地（Amadus Basin）的奥拉米纳（Ooraminna）区域开展了地震勘探。本次勘探记录了深井（Deep Well）与爱丽丝泉（Alice Springs）之间的反射波测线，以及横穿奥拉米纳背斜（Ooraminna Anticline）高点的测线，并在奥拉米纳背斜的轴部开展了折射波深度探测。本次勘探的目标是获取传教士平原（Missionary Plain）东部区域的盆地构造，以及奥拉米纳构造的相关资料。勘探结果显示，深井至爱丽丝泉一带的盆地整体呈向斜构造，奥拉米纳背斜北侧的沉积层最大厚度可达20000英尺。地震证据表明，深井隆起与奥拉米纳背斜均源于深部地层增厚，该地层暂被鉴定为比特斯普林斯地层（Bitter Springs Formation）。本次勘探未能将剖面中的反射层与麦克唐奈山脉（MacDonnell Ranges）及奥拉米纳背斜的出露地层建立关联。
