HCA Training Modules
The model courses contain sets of related modules. In practice, courses are tailored to suit the clients needs and the local terrane type. Training is most effective when courses are delivered in-house and on-site.

1) Elementary modules Entry-level modules tailored for geological staff whose professional background training has been very weak. Includes basic training to recognise and correctly measure bedding; to understand and use combined structural and topographic information; to construct and interpret basic geological maps; and to construct basic cross-sections from field data.

2) Underground mapping modules Basic tools and skills required to produce effective underground geological maps. The course concentrates on providing maps that maximise the data available.

3) Basic structure modulesBasic structural geology modules common to all terrane types and situations plus sufficient theoretical background to handle anomalous structures. Includes oriented drill-core procedures,with both stereographic and computer processing of results... Aimed at providing refresher courses for geological staff whose structural memory is rusty.

4) Thin-skinned structure modules Geometry, theory and structural tools required to work in dominantly thin-skinned terranes. Includes the gathering and use of dip domain data; the gathering and use of fault kinematic data; construction of balanced cross-sections dealing with thin-skinned and thick-skinned components; recognition of detachment surfaces; linked fault and relay (accommodation) geometries; ...

5) Ductile structure modules Structural tools and skills specific to moderately deformed ductile terranes in low to high grade metamorphic rocks. Includes recognising, measuring, and using basic structural foliations and lineations; recognising and using bedding facing and vergence; applying cross-section techniques appropriate to plunging folds in cleaved rocks; using stereographic projections...

6) Advanced structural analysis Tools, skills and theoretical background required to interpret multiply deformed complex structures and shear zones in metamorphic rocks of all grades. Aimed at training geologists working in complex terranes, particularly in metamorphic rocks, or providing in-depth background for procuring, evaluating, and understanding the output of structural specialists and consultants in such terranes.
