Quick PD: From Continental Drift to Plate Tectonics

October 14, 2021 @ 4:00 PM

From Continental Drift to Plate Tectonics

Thursday Oct 14 @ 4.00pm AEDT. Register here, it's FREE.

The idea of a dynamic Earth has had a long history. In 1596 Abraham Ortelius proposed that modern Spain and Northern America were at one point attached to Africa, only to have been torn away by earthquakes and floods. Many other naturalists, puzzled by the geographical of distant coastlines, had proposed similar ideas. But evidence was lacking. The discovery of large submerged mountain chains, and later, palaeomagnetism within oceanic rocks, provided geologists with the evidence they needed. Not until after the 1970s did scientists fully grasp that Earth was divided into plates that were, in places, growing apart and in others colliding. Plate tectonics has provided the evidence to interpret how many different types of minerals and rocks had formed.

This PD will take no more than 30-45 minutes of your time. Extra time for Q&A can follow as required.

Quick PD: How Plate Tectonics Work

October 21, 2021 @ 4:00 PM

How Plate Tectonics Work

Thursday Oct 21 @ 4.00pm AEDT. Register here, it's FREE.

The continents are on the move! Here we explore the driving factors behind plate tectonics including mantle convection, slab push and pull, and the influences of heat and gravity. We take a closer look at the different plate boundary types: convergent, divergent, and transform, and all the associated structures from subduction zones to continental rifts. We take a look back in time to see how the continents have changed, and look forwards to see where they’re heading next.

Quick PD: Rocks and Tectonics

October 28, 2021 @ 4:00 PM

Rocks and Tectonics

Thursday Oct 28 @ 4.00pm AEDT. Register here, it's FREE.

Rocks that have been altered by heat and pressure are called metamorphic rocks. This heat and pressure is mostly seen at plate margins where regional and hydrothermal metamorphism occur. In this lecture we look at how rocks change when we apply various degrees of heat and pressure and release them. The resulting rocks are not only beautiful, and used in masonry or as table tops, they also contain the minerals that drives economic geology, such as iron, copper, lead, silver and gold. We will investigate where we can find these rocks in the Macquarie Arc located in central western NSW..

Quick PD: What are fossils?

October 29, 2021 @ 4:00 PM

Fossils! - session 1

What makes a fossil a fossil?

  • What are fossils?
  • Where do we find them?
  • How do we recognise them?
  • How do they form?

This PD will take no more than 30-40 minutes of your time. Extra time for Q&A can follow as required.

GM Trilobite

Do you have a mystery fossil or two in your prep room? Take some good quality photographs and send them through ahead of time* and we'll try and do some virtual ID for you too!

* Send photographs of mystery fossils here. Good resolution and depth of field is essential.
Make sure photographs include some form of scale.
NOTE: Identifying fossils can be hard at the best of times and doing it from photographs is far from ideal. We make no promises we can indentify anything or get it right even if we give it a try!  However, one thing is for sure: if we cannot easily identify a specimen chances are it should not be in a school teaching set!

Quick PD: Volcanoes and Magmatism

November 04, 2021 @ 4:00 PM

Volcanoes and Magmatism

Thursday Nov 4 @ 4.00pm AEDT. Register here, it's FREE.

Not all volcanoes are the same, and a number of factors contribute to the size, shape, and eruption style of different volcanoes. Different tectonic settings influence magma sources, physical properties of magma, and geochemistry of magmas. Here we will explore where magma is generated, how it moves through the crust, how it changes over time, and what happens if it does or doesn’t erupt. We also take a look at some ancient and more recent examples of magmatism and volcanism in eastern Australia and how it has affected our local landscapes.

This PD will take no more than 30-45 minutes of your time. Extra time for Q&A can follow as required.

Quick PD: How do we tell time with fossils?

November 05, 2021 @ 4:00 PM

Fossils! - session 2

How do we tell time with fossils?

  • What is the Law of Superposition?
  • What is stratigraphy?
  • What is correlation and how does it work?
  • What is the difference between absolute and relative dating?
  • What is an index fossil and why are they so useful?

This PD will take no more than 30-40 minutes of your time. Extra time for Q&A can follow as required.

Quick PD: Landforms and Tectonics

November 11, 2021 @ 4:00 PM

Landforms and Tectonics

Thursday Nov 11 @ 4.00pm AEDT. Register here, it's FREE.

Plate tectonics shapes the world we live on. Convergent and divergent margins shape the landscape, but so does mantle convection. The up and down-welling of the mantle creates a dynamic topography thousands of kilometres from plate margins. We will look at a few examples of dynamic topography from Australia. Subduction too has shaped the Australian landscape. Australia is currently tilting to the north-east as it slowly sinks under the Pacific plate. The consequences of this tilt has drained the Murray Basin, and left the Nullarbor high and dry.

Quick PD: Natural Hazards

November 18, 2021 @ 4:00 PM

Natural Hazards

Thursday Nov 18 @ 4.00pm AEDT. Register here, it's FREE.

Active plate tectonic processes bring with it a number of natural hazards. In the final presentation in this series, we explore the tectonic causes of these hazards, including earthquakes, tsunamis, volcanoes, landslides, and more. By building up our understanding of how plate tectonics cause these hazards we are able to mitigate many of the risks posed by living in tectonically active areas. 

This PD will take no more than 30-45 minutes of your time. Extra time for Q&A can follow as required.
