Critical minerals are necessary to all of the key energy technologies of the future, including solar, wind, energy storage, and electric vehicles.
‘There are few, if any, remaining major, new mineral deposits that are exposed at the Earth’s surface still to be found in Australia. The technical challenge of cost-effectively finding major, new mineral deposits hidden beneath a veneer of regolith or sediments, much of it only a few hundred metres thick, has not yet been met.’[From https://minexcrc.com.au/about-minex-crc/what-is-minex-crc/]
How Can MGPalaeo Help?
Gaining an accurate picture of the cover sediment and a better understanding of the sub-surface geology will be crucial for the ongoing success of exploration in the minerals industry.
MGPalaeo has many years of experience working with a range of mineral companies over a diverse portfolio across Australia, including uranium, nickel, gold, iron ore, base metals, minerals sands, and more.
As minerals become increasingly vital to our shift to a low carbon society, and exploration focuses on discovering new mineral deposits hidden beneath the surface, MGPalaeo is ideally positioned to help provide answers.
Biostratigraphy can be used to target, characterize, and prioritize key areas for exploration by providing age and stratigraphic control, while our comprehensive range of sedimentological services can lead to a better understanding of stratigraphic development and depositional models.

What Can Be Sampled For Palynology?
Palynomorphs (spores, pollen, dinocysts, etc) are microscopic and settle more readily in low energy environments. As such, it is always best to target dark-coloured mudstones or siltstones first for palynology.
But don’t let sandstones discourage you; unless the sands are very clean, you should still have good microfossil recovery. In some cases, palynological results from sandy lithologies are even better than the encompassing mudstones. A general rule of thumb is that as grain size increases, the volume of material collected for sampling should likewise increase.
Lignite, peat, and coals can also be worth sampling, too. When it comes to dating coals or even coal seam correlations, it is the lithology directly above or below a coal that is generally sampled, while the coal itself is avoided. But we often find that a good suite of palynomorphs can be extracted directly from coals, thereby allowing far more accurate age determinations and correlations.
