Default [8/1] Obsidian Abundance as evidence for Volcanic History and Unanswered Origin of Cnaith Region

(The following paper was written in Cnaith and sent to Forsilvra for publishing. It is written using jargon perhaps only stratigraphists would understand.)

Obsidian Abundance as evidence for Volcanic History and Unanswered Origin of Cnaith Region

Jezebel Hughes*, Quinn Valentine, Lyon Dagos

August 1st of 241

The Cnaith region of Lacharn is an isolated mountainous area that is heavily forested and rests are slightly higher altitudes than the rest of the coastal regions of Lacharn. The large mountain range bordering the interior of the craton harbors examples of heavier rocks indicative of continental collisional activity as we have seen in Ahestere. It is similar, but on a smaller level than the continent of Ahestere.

Our group has also identified numerous layers of basaltic rock (it is very black, and very smooth, but it is not Obsidian) surrounding the Cnaith region, when the outcrop is visible, this type of rock is only found in these abundances when the region in question is indeed a coastal region. It is not because Cnaith is a coastal region, however, that we find basaltic rocks here, we have also identified shallow waters to hold amounts of basaltic rock anywhere in the world. Basaltic rock, thus, forms somewhere within the water. It is unknown why, and why it is a different color than inland continental rocks. The current theory is that properties of water affect the rock when the magma cools and hardens, and the particular resulting rock retains some of the properties of water (i.e. darker color, less dense).

The current hypothesis, then, is that, much like Ahestere, the Cnaith region was once separate from Lacharn itself. Further out to sea, much farther to the east somewhere, perhaps eons ago. It is impossible currently to suggest when this event may have occurred. We think this because Cnaith, relative to Lacharn, is actually quite young. It is made up of only basaltic rock, a rock from the sea, which we have confirmed is younger than the continental rock of inner Lacharn through the principle of superposition. Therefore, it was created somewhere to the east, and then crashed into Lacharn.

The mechanism for this particular movement is still unknown, but it would make less sense for Cnaith to be apart of Lacharn originally. Our group has, however, identified significant deposits of obsidian, a rock made of fast cooling magma from volcanoes. Or rather, obsidian is magma that reaches water fast. Another name for it is lava glass. It is peculiar to observe that these types of samples are everywhere around Cnaith. Some locals even use the obsidian to fashion farming tools, or to bargain with, or use as arrow tips, it is a common occurrence in this are. This abundance of obsidian suggests volcanic activity at some point, the problem with this hypothesis is that there is no observable volcano in the region, or at least nothing worth noting.

Referring back to earlier in the paper, this is why we suggest that Cnaith formed somewhere out at sea, and then crashed into Lacharn, if there were a volcanic range nearby, we would then suggest that Cnaith formed this way.

Whereas on Ahestere there are plenty of dormant volcanoes (even if the locals don't want to believe it, they're there). Cnaith's western mountain range is only made up of dense, continental rock, and has never erupted. Does this mean that the "lava glass" abundances formed without lava?

Of course not!

This is a new mechanism we are dealing with in Cnaith, and our group will get to the bottom of this particular mystery.
