Science Saturday: How to make Limestone

Limestone is a type of sedimentary rock made by chemical processes (dare I say, a chemical sedimentary rock) rather than physical processes (what we call a clastic sedimentary rock).

Limestone in Big Cottonwood Canyon, Utah with my hammer for scale.

Limestone is primarily composed of the mineral calcite or aragonite which precipitate out of water containing dissolved calcium ions.

(CaCO3) Calcite and aragonite chemical formula

This can happen through both biologic and non-biologic processes. About 20-25% of all sedimentary rocks are carbonates and most of those carbonates are limestone. The remaining carbonates are mostly dolomite (or dolostone to avoid confusion with the mineral dolomite) which differs from limestone due to it's high magnesium content.

Dolomite Peaks, Italy

In fact, physically, you can't tell dolomite and limestone apart (at least not to my knowledge, I work in clastic sedimentary rocks so if you're reading this and you work in carbonates, feel free to chip in), usually just lump all carbonates I see as limestone. Technically, there are few things you can test physically but you absolutely need the right tools. Dolomite is slightly harder than limestone and does not as readily dissolve in HCl (fizzes less). Sometimes you can see a change but often they are just too similar to tell in my experience.

Limestone is commonly gray to white though iron or managnese can make it yellow, or red and high organic content can make it almost black.

But how is limestone formed? One way is through biochemical processes. Many marine organisms have learned to precipitate a calcium carbonate shell. When these organisms die, they fall to the sea floor. Eventually, they are turned into bioclastic limestone with chemically precipitated calcite cement between them.

One type of bioclastic limestone is finely-grained chalk like the White Cliffs of Dover which formed from coccoliths. Chalk can be formed from algae, foraminifera and plankton. It is very soft, porous version of limestone.

Limestone can also form chemically, precipitating straight out of the water as such: H2O + 3CO2 -> CaCO3.

And now you know the basic ways to make limestone.

Geology and The Terror

As a geologist who is incapable of turning off their geology brain even while watching shows for fun, one of the things that baffles me a bit about The Terror is why they continuously refer to the landscape as shale when both King William Island and the filming location in Pag, Croatia are dominated by limestone. Given the desolation of the landscape, the geology is rather at the forefront of many scenes so it was fun to try and parse it out as I watched.

King William Island, Nunavut, Canada

According to the official map of the bedrock of the region as published by the Canadian government (Harrison et al., 2015), the entirety of King William Island is mapped as dolostone, dolomitic limestone, and limestone with only minor components of shale, sandstone, conglomerate, and breccia. This is a shelf marine deposit dating back to the Late Cambrian, so this is very old sedimentary rock but younger than most of the surrounding hard rock that composes various parts of the Canadian shield. Notably, the pink units mapped on the Boothia Peninsula are Paleoproterozoic in age (2.5-1.6 billion years old), potentially up to 2 billion years older than the limestones of King William Island.

(This is an absolutely massive .pdf file with some scaled features so I would recommend viewing via the official publication to actually read anything or see fine details: publications.gc.ca/pub?id=9.557274&sl=0)

Notably, this map was published in 2015, 8 years after the novel was written. However, according to the bibliography for the map (which can be accessed via the previous link) a preliminary geologic map has existed for the area since at least 1967, though I was unable to track this publication down online. The novel was clearly thoroughly researched and Dan Simmons could have easily accessed this publication and others through multiple institutions.

The surficial geology of King William Island has also been mapped, and is predominantly glacial, as one would expect given it's location. For those unfamiliar with glacial geology processes, this is basically saying that the bedrock is buried under a bunch of glacial deposits. Glacial till is composed of rocks and sediments plucked from the bedrock and ground up. This is why the surface of the island is not one big rock, but a bunch of smaller pieces. Interestingly, the material on the southern part of the island is sandier because it contains more material derived from the Canadian Shield further south. If you're interested in glacial geology, I highly recommend zooming around a bit on Google Earth because the features here are GORGEOUS.

(This map is absolutely massive and the lines scale with zoom so it's hard to see at this resolution, access it here: publications.gc.ca/pub?id=9.834073&sl=0)

(Google Earth Pro, satellite imagery from 2020)

According to the surface geology map and Google Earth, the actual landscape of King William Island is much more water logged than it appears in the show. It's not entirely impossible that there has been some geomorphological change since 1848, but most of the features mapped would have been formed during the last ice age and as the glaciers melted and not more recently. This would have been handy for the men of the Franklin Expedition because each of these pools is filled with freshwater.

Pag, Croatia

Tracking down a geologic map of Croatia was somewhat challenging as I don't speak Croatian. I was able to find a map of the whole country, and while it's all in Croatian the symbol for the geologic time periods is universal so time periods can be correlated. This shows that the units that make up Pag are Cretaceous and Paleocene-Eocene in age.

(Map accessed here: https://www.hgi-cgs.hr/en/geoloska-karta-republike-hrvatske-1300-000/)

I was able to find a .pdf (access here: http://kig.kartografija.hr/index.php/kig/article/view/158/274) that had a bit more information on the map above but at a lower resolution. This states that the Cretaceous units are dominantly carbonates from the Adriatic sea and the Eocene units are also carbonates. This makes sense as both the Cretaceous and Paleocene-Eocene boundary/PETM are times of increased global temperature correlated with increases in global sea level.

As always, the best geology website out there, Macrostrat, also came through on the unit lithologies. I was unable to access the source listed on Macrostrat, but both the Cretaceous (green) and Paleocene-Eocene units (orange) are listed as limestone.

(Source: https://macrostrat.org/map/#x=16&y=23&z=2)

One of the best views that we get of the geology on Pag is the last scene with Bridgens in episode 9. During the zoom out of this scene we get a really nice view of the bedrock and debris covering it.

Given all of this, I'm really not sure where the landscape description as shale came from. If there is historical precedence for calling the rocks on the island shale, let me know! I have read a few books but none of the primary sources from the expeditions to this region, so if it comes from that I wouldn't be surprised.

Overall though, I have to say that the filming location was well chosen given the similarities it holds to the geology of King William Island.

A headcanon about the formation of the forgotten vale

The reach has been proposed to be a karst landscape*, which tend to be characterised by fields, as well as water drainage by caves and sinkholes. These features are formed by dissolution of rocks like limestone.

Though in this context, glaciokarst may be more accurate, as the mountain ranges of the western reach contain at least one valley in addition to their many cave systems; two of which are specifically referred to as glacier-like (glacier crawl in shadowkey and glacial crevice in dawnguard). This, in addition to the unusual narrowness of the valley, may suggest that the region was once occupied by an ice cap that has melted and collapsed into its tunnel valleys over the years. This narrowness may be due to (40-500 metres of) overdeepening, which is characteristic of iceways, as well as providing a sediment layer in the vale for water to seep into. The collapse of the ice cap into an existing valley, particularly in the limestone and dolomite bedrocks of a karst*, would create solution caves as the water moved downward, such as in Darkfall Passage. (This is consistent as well with the shape of other cave systems in the region, which include Earthtear Caverns, Fearfrost Caverns, and Loth’Na Cavern.)

The continued existence of the glacier (see: the entrance to the glacial crevice) creates meltwater streams, which are quite possibly the source of the water in Darkfall Cave. It is my belief that as this water continues to move towards sea level, it joins the Karth river by way of the stream at Deep Folk Crossing. As well, the glaciofluvial deposits would contribute to the unique fertility shown in the area over several games.
