| As a consequence of the antiquity and relatively short duration of mining, little was known of the mineralogy of the Pittsville iron deposits. |
| Normally, in mineralogy, argentiferous gold containing 20-25 per cent of silver is referred to as electrum. |
| No information was available on the mineralogy of the mine beyond the metals assayed during exploration. |
| This mineralogy is consistent with derivation from granitic or acidic high-grade metamorphic rocks. |
| A difference is also observed between the mineralogy of the arenosols of the north area from the ones developed in the south coast. |
| The specimens were then ground to a fine powder and analyzed individually in an X-ray diffractometer to determine carbonate polymorph mineralogy. |
