NOTICE TO CWEDG’ers
The Australian Geodynamics Cooperative Research Centre (AGCRC), Geological Survey of New South Wales (GSNSW), Australian Geological Survey Organisation (AGSO) and Fractal Graphics will hold a 3 day workshop in Orange to present results of their recent work in the Eastern Lachlan Orogen.
Programme, Registration and Contacts
March 7-8, Field trip on the 9th.
The core of the workshop will be a discussion of the results of the deep seismic reflection and refraction data, collected in 1997 and 1999, designed to shed light on crustal architecture of different belts of Ordovician volcanics, volcaniclastics and intrusives that form part of the Macquarie Arc. This arc was disrupted during Silurian and Devonian extension and by later contraction. The work was also designed to contribute to the understanding of the geodynamic setting of some Lachlan Orogen mineral systems. North-south and east-west seismic data were acquired across the Molong volcanic belt north and south of Orange; and east-west lines were acquired across the Junee-Narromine volcanic belt south of Lake Cowal, and several kilometres north of the Gidginbung deposit.
