**4.1 TGA-MS analysis of olivine (Norway) and olivine (Netherland)**

Olivine (Norway) and Olivine (Netherland) were analysed using TGA coupled with MS (Mass Spectrometer). Results are presented in **Figure 14**.

These results at least partially confirm that Olivine (Netherland) has more lizardite and is 53.01% as shown in **Table 4**. This verifies QXRD analysis. Dunite for this research was handpicked from Doonba deposit in vicinity of a small village/town Barbara, close to Tamworth city. **Tables 5** and **6** and other following tables present

phases present in this dunite. Sub 75 μm dunite have 61% lizardite, 29% olivine, 8.3% brucite and 1.3% magnetite [18]. Percentage phases for other dunite fractions (20–45 micron, 45–75 micron and sub 20 micron) are presented in **Table 6**. An example of calibration curves for TGA-MS calibration is provided in **Figure 15**, routinely calibration was performed. Dunite is used here for calibration.
