Higher than normal concentrations of iridium were first found in sedimentary layers in 1980 and they are the first hard evidence of a meteorite impact event associated with the K-T extinction. Higher than normal iridium concentrations have been found in more than 100 places on earth, making it useful for dating.

  • Advantages of Going Fossicking with the club

From the newsletter:

You have the options of going with the club or going it alone.

So what advantages are there in going with the club?

  • You will not require a fossicking licence as you will fossick under the Club’s licence.
  • You will be guided by a savvy Field Trip Officers who will ensure that:
    1. You go to the right place (maps, designated fossicking areas, best places to dig)
    2. You know the fossicking rules and etiquette. (e.g. leave no craters behind, don’t jump claims etc)
    3. Advice on fossicking equipment, clothing, etc. (You can get this info. online too)
    4. You find nearby suitable accommodation for your particular needs.
    5. You know what to look for. (There’s a lot of different rocks out there)
  • You will be able to join in the post-fossicking get together to relax, skite about your finds and learn even more about the minerals specific to your area etc. Lots of laughs and good fun!
  • There’s safety in numbers. If you get into a spot of bother, it’s nice to know there are people who will look out for you…or even look for you if you wander off!

If you go by yourself……well you are on your own aren’t you?

CMLC Newsletter Jul 2020:

  • Member works photos
  • Pros and Cons of using jewellery base materials other than gold and silver

CMLC Newsletter Jun 2020: Learn about oxygen, a reactive corrosive and chemically very simple essential element in the grand cycle of life. Lots of minerals contain complex oxides (bound oxygen) or hydroxides (bound oxygen also bound to hydrogen), indicating oxygen has reacted with (or corroded) other elements. When mineral ore is processed a lot of energy is required to remove oxides and hydroxides, gold being an exception. An excellent example is converting bauxite to elemental aluminium which requires a lot of electrical energy.

Plants store energy from the sun as growth and produce oxygen as a waste byproduct using a unique and complex chemical pathway that has barely altered, in contrast to the variety of life it has given rise to. Animals get to use the sun’s stored energy as food from plant growth, using the reactive corrosive power of the waste oxygen to release energy from the sun’s stored energy for independent and stimulus responsive mechanical animation, among defining qualities of what an animal is.

CMLC Newsletter May 2020: Interesting article on how the same chemical element, carbon, has wildly differing physical properties in its elemental form depending on how it bonds to itself. Also interesting article by Leigh Twine and Jenni Clark on Topaz and Diamonds at O’Brien’s Creek fossicking area with maps and photographs.

CMLC Newsletter Apr 2020: 150 km west of Cairns, Mt. Mulligan, a still gazetted ghost town, is well known to gold fossickers with metal detectors and the area still has active mining leases. 1878 was the peak year for gold production (a massive 44 000 ounces). In 1921 75 men were killed by a coal dust explosion. Leigh Twine and Jenni Clarke provide an account of the disaster with maps and photographs.

CMLC Newsletter Mar 2020: Mike Rashleigh, who has toured the Argyle Diamond Mine, writes about the mine, its unique coloured diamonds, its major market influence and its planned closure in 2021.

CMLC Newsletter Feb 2020

CMLC Newsletter Jan 2020:
Practical and interesting observations on one of the great achievements of science on pages 4, 5 and 6: The Periodic Table Of The Elements. Some additional information: the columns were originally defined as measuring valency, something with a strict experimental measurement meaning that was discovered to be periodic as atomic weight rose. If you are a student don’t give this answer in an exam. Something safe like stating columns indicate number of electrons in outer shell will get you full marks. If you are looking to impress you can also add row fullness or occupancy shows how many electrons there can be in outer shell in that range of atomic weight.
