PROJECT OBJECTIVES: P384
1. To determine the primary geological, geochemical and structural controls on the location and timing of base metal deposits in sedimentary basins.
2. To understand the chemical and hydrological evolution of metalliferous brines in selected Proterozoic sedimentary
basins of Australia.
3. To develop basin metallogenic models and specific ore deposit models that may be used in the exploration for large-tonnage base-metal ore deposits.
This research project involves a multi-disciplinary
approach using regional geological, geophysical
and structural studies, brine chemical modelling and
geochemical and isotopic halo studies to provide a
foundation on which to build a network of
exploration criteria and ore deposit models for
major sediment-hosted base metal deposits.
The project consists of three research modules as
This is the third major report on the project and outlines results to date on the Deposit Halos module. A comprehensive account of deposit halo mineralogy and geochemistry is presented for Lady Loretta and HYC. The results have major implications regarding mineral exploration and ore genesis for giant stratifonn Pb-Zn deposits.
A further report (No. 4), covering work on the Basin Analysis and Brine Chemistry modules, will be distributed to sponsors at the November 29/30 meeting.
It is now 18 months since the commencement of this project and research progress in all aspects of the work has been very pleasing. Acknowledgment for our progress to date is due to the excellent work by the CODES research team and the close cooperation provided by the sponsor companies,
AGSO and the NTGS. In particular, for the deposit halos module, we would like to acknowledge Mel Jones and Pancontinental for their support and encouragement on the Lady Loretta study.
