Ore Textures and Breccias Recognition Techniques and 
Core Logging Techniques

27-31 January 2017

James Cook University
Townsville QLD

This 5 day course, in 2 modules, is being offered to  industry geologists and, to students who are not enrolled in an Honours or Masters program, as an opportunity for short duration professional training . The training is part of the honours coursework program at JCU in 2017 so, participants will work alongside current JCU honours students. As part of the coursework, assessments will be included in both modules. Participation can be be for one or both modules.

Module 1 Ore Textures and Breccias Recognition Techniques

Dr Gavin Clarke
27-29 January 2017

This module is designed to introduce participants to the fundamentals of textural observation and interpretation in mineralised hydrothermal systems. The techniques are simple, highly effective and require no specialised equipment for their implementation. The techniques taught are also extremely practical in that they generate numerous questions concerning the mineralisation being studied and commonly provide vectors toward mineralisation for drill testing.

Module 2 Core Logging Techniques

Prof. Paul Dirks
30-31 January 2017

This module aims to teach participants the basic skills and methodology required to review and log geological core. Emphasis will be placed on the recognition, description and acquisition of oriented data (bedding planes, faults, fractures, shear zones), and how this data relates back to field observations. No prior experience in core logging is assumed, the aim being to familiarise participants with the key requirements of core logging, and how logs should be interpreted and integrated with geological models.

Course Description

Mineral geochemistry and its application in exploration

In the recent years mineral geochemistry has been demonstrated to contain subtle primary signatures of hydrothermal mineralising systems, and can be used as indicators up to ~10km from orebodies, and as vectors towards orebodies. This tool was only developed and became available in the past decade with the development of laser ablation – inductively coupled Plasma – Mass Spectrometry (LA-ICP-MS) analytical methods. This module will cover the LA-ICP-MS methodology and the application of mineral geochemistry in exploration.

Structural controls of mineralisation

This module will look at the principles behind structural controls on mineralisation through analysis of structures, geomechanical modelling, case studies and practical exercises. Structural controls are explained by the interactions of stress, deformation, fluid flow and heat. The module will present a selection of modern structural geology and spatial analysis techniques that have practical applications in exploration and mining geology.

3D geological modelling of hard rock deposits using Leapfrog Geo

This module aims to enhance attendees’ data analysis and communication skills through the application of Leapfrog Geo, an industry-leading 3D modelling and communication package. The hands-on training will include a major overview of software functionality on a training dataset then will move on to attendees working up a number of real-world datasets. This will enable students to apply the analysis to their own data if desired. The modelling will explore the relationships between lithology, alteration and structure to identify and model controls on fluid flow / metal distribution and hence exploration projection. The underlying principles behind the software application and geological parameters will be discussed as will ways to ensure optimisation of modelling outputs. There will be a strong focus on relaying findings and understanding to peers using the software during the course.

Modelling the spatial distribution of mineral deposits

This module will introduce the concept of fractal and multifractal analysis and their practical applications in mineral exploration and mining. Fractal analysis of the spatial distribution of mineral deposits will be discussed, as well as evaluating geological complexity and complexity gradients which can provide insights into controls on mineralisation. The concept of multifractal analysis will be presented to investigate the distribution of geochemical data and its practical application in geochemical anomaly mapping.

Advanced Field Training

21-28 June 2017 - (excluding travel days to and from Cloncurry)

Roxmere  Station and Cloncurry Region
Cloncurry QLD

Course Leaders:
Prof. Paul Dirks
Dr Ioan Sanislav

Course Information (pdf)

This intensive 8-day course is designed to provide geoscientists with essential exploration-related field skills in complexly deformed and altered rocks. Real field mapping is a dying art and this course does not encourage wandering around with a GPS making random observations. Genuine ‘form surface’ mapping of contacts, alteration zones and structures will be integrated with paragenesis, geophysical interpretation and the use of alternate knowledge-based and data-based exploration models, including an introduction to the simple and useful application of semi-quantitative prospectivity tools.

The course will include

  • Veins, breccias, shear zones: paragenesis, overprinting, mechanisms, geometry
  • Advanced structural geology and structural controls
  • Developing exploration strategies from field observations
Module 1

Mary Kathleen-style uranium - An area of awesome exposure and outstanding geophysics forms the basis for this module. This is an ideal module for those wishing to appreciate alteration recognition in the field, basic structural geology, skarns and intense metasomatic activity, and correlation of geophysical data sets with geology in order to identify drill targets. A visit to the old Mary Kathleen uranium mine forms the basis for developing the exploration strategy, prior to the appraisal of the field area, which contains several U prospects that have been the subject of recent exploration interest.

Module 2

IOCG deposits, breccias and crustal fluid flow - The Eastern Succession of the Mount Isa inlier is world renowned for its variety of IOCG deposit types. This module will examine field aspects of exploration for IOCG deposits, emphasising characteristion and mapping of breccias and fluid systems in the field.

Course Description

The Snake Creek Anticline area is located ~ 800 km west of Townsville, near Cloncurry, on the eastern side of the mid Proterozoic Mt Isa Inlier, NW Queensland. The field area contains spectacular examples of well exposed, multiply deformed and metamorphosed turbidite sequences juxtaposed against calcareous siltstone and limestone. The entire sequence was intruded by a wide range of igneous rocks varying from gabbro to granite. There are various types of breccia and mineralisation in the area. In this workshop we will examine and map the spectacular metamorphic rocks, structures, igneous rocks, breccias, and mineralisation and check their relationships.

Metamorphic highlights:

  • A classical regional low-pressure high-temperature metamorphic terrane
  • Metamorphic grade varies from biotite zone to kyanite and sillimanite-K feldspar zones
  • Spectacular outcrops with centimeters size andalusite, staurolite and kyanite, plus smaller garnet porphyroblasts
  • Well-defined metamorphic isograds
  • Contrasting metamorphic assemblages with metamorphosed turbidite occurring next to metamorphosed  calcareous siltstone
  • Up to five metamorphic events proposed over ~ 150 Ma

Structural highlights:

  • Well preserved sedimentary structures with clear younging indicators
  • Up to five folding events with folded structures from kilometer scale to tens of meter scale to meters scale well preserved and forming mappable units
  • At least three, easy to recognize, overprinting foliation events with up to five overprinting foliations recognizable by skilled structural geologists
  • Easy to recognize and map regional scale faults (Cloncurry Fault)
  • Different deformation styles between the calcareous siltstone and the turbidite
  • Well-developed early extensional structures in the calcareous siltstone
  • Different type of breccia in the calcareous siltstone
  • Well-developed breccia-pipe structures

Igneous highlights:

  • A complete igneous suite from gabbro to granite occurs as plutons and dykes
  • A beautiful example of layered intrusion complex with a well-defined crystal fractionation sequence from gabbro to tonalite
  • Complex intrusive and structural relationships
  • Multiple generations of mafic dykes and sills metamorphosed to amphibolite facies
  • Spectacular examples of structurally controlled pluton emplacement mechanism

Alteration and economic geology highlights:

  • A world class metallogenic province with SEDEX, IOCG, skarn and shear zone hosted deposits. There are many mines around, including IOCG deposits such as the classic Ernest Henry deposit plus E1, Great Australian, Rocklands, Eloise, Little Eva, and Mt Watson-Cuthbert, Broken Hill Type deposit such as Cannington, skarn deposits (Mary Kathleen, Elaine, Mt Colin, Mt Elliott), and the world’s largest cluster of SEDEX deposits (Mt Isa, George Fisher, Hilton, and Dugald River.
  • Regional scale albite alteration. Scapolite crystals of centimeter size (up to 20 cm) in some altered siliciclastic rocks. Widespread actinolite, quartz, calcite, barite, specular hematite, magnetite and sulfide alteration.
  • Well-developed alteration assemblages typical for IOCG and skarn deposits
  • Meter scale hydrothermal magnetite veins
  • Visits to active mine sites and past exploration prospects
