| 41. | Tungsten ore deposits are predominantly magmatic or hydrothermal in origin and are associated with felsic igneous intrusions.
|
| 42. | Xenoliths that originated in the Earth's crust include rich metamorphic rocks and felsic intrusive rocks.
|
| 43. | The felsic footwall is subject to a pronounced stretching lineation which increases in intensity to the north.
|
| 44. | This is interpreted to occur due to competency contrast between the felsic footwall and the ultramafic unit.
|
| 45. | The slopes of the peak are highly unstable, consisting of weak, hydrothermally altered felsic rocks.
|
| 46. | Gold is associated with silicic, kaolinitic, and pyritic alteration of greenschist-grade felsic metavolcanics.
|
| 47. | The largest of the less common felsic lava flows is located between Link Lake and Turtle Lake.
|
| 48. | Mafic melts contain low levels of dissolved gases whereas felsic melts contain high levels of dissolved gases.
|
| 49. | The ages of these felsic rocks are generally between 2.5 and 3.8 billion years.
|
| 50. | Felsic and mafic rocks tend to be less affected by carbon dioxide due to their higher aluminium content.
