June Hill (CSIRO) presents 'GeoLena' synthetic modelling platform for benchmarking geodata analytical techniques.

1. Synthetic geology data set
For drill hole data
MINERAL RESOURCES FLAGSHIP

2. Presentation title | Presenter name2 |2 |
UNKNOWN
real geology
Rocks are made up of collections of minerals
(with specific composition and texture).
Rocks are affected by structures.
SAMPLE & MEASURE
chemical and physical
properties
Measurement values depend on geology,
measurement type, errors, and sampling
strategy. e.g. XRF, XRD, hyperspectral, images
MODEL
geology model
Algorithms performed on the data provide
higher level geological information from
which we can create the geological model.
e.g. primary rock type, alteration, structures
PREDICT
new information for
decision making
Algorithms predict useful information for
minerals exploration and mining. e.g. predict
mineralisation and rock properties
Real World Scenario
WORKFLOW How good are our
intepretations, models
and predictions?
