    If the that the present is the key to the past is valid (meaning the same geologic processes occurring today occurred in the past), then sediments laid down during the Precambrian would have likewise been controlled by the movement and geographic position of the continents.Thus, it can be inferred that the extensive evaporites dating to 3.5 billion years ago from the Pilbara region of Western Australia could not have been formed within or near the poles.It can also be inferred that stromatolite-bearing dolomites of rock, a sedimentary sequence spanning the period from 1.65 billion to 800 million years ago, were deposited in warm, tropical waters.Riphean rock is primarily located in the East European craton, which extends from Denmark to the Ural Mountains, and in the Siberian craton in Russia.Around 35 people from various research institutions, service providers and the mining industry attended the workshop from across Australia. The day started with a tour of the John de Laeter Centre (Jd LC) facilities incorporating the Tescan integrated mineral analyser (TIMA; ), which was the key instrument of relevance to the workshop. Dr Mark Aylmore, recently appointed to take on the role of Applied Mineralogist in the Jd LC, chaired the workshop that included presentations from: • Dr Kamran Khajehpour (AXT), who gave an overview of automated mineralogy and supported by Esben Kjaer (Struers) who gave a brief overview on sample preparation techniques.

    It is used in the manufacture of porcelin and for other industrial purposes.

    The John de Laeter Centre provides quantitative data used to understand processes of Earth and planetary evolution, characterise the nature of resources and materials upon which our society depends, and monitor our changing environment.

    The Centre is open to collaborative research projects, non-collaborative access to the equipment by qualified users for research purposes, and commercial services.

    During the long course of Precambrian time, the climatic conditions of the Earth changed considerably.

    Evidence of this can be seen in the sedimentary record, which documents appreciable changes in the composition of the atmosphere and oceans over time.
