HPT 101: Lesson 6: The Origin of Limestone

By ellenjmchenry Uncategorized Comments Off

In this lesson we wonder how there can be so much limestone across the planet and we see how a simple chemical equation (not to mention common sense) disproves what most geology books teach about limestone.

Some very short videos reminding us of the mainstream explanation of limestone:

This is about as detailed as any explanation gets, and it is still less than 2 minutes long. https://www.youtube.com/watch?v=NX4BTiCtuto

This is very cute and has nice music: https://www.youtube.com/watch?v=WMX3BJZHgi4

Here we see the shelled creatures that supposedly made the limestone. https://www.youtube.com/watch?v=1z34geFooiE (Does the presence of shelled animal fossils in the limestone prove that they MADE it? We can find many areas of limestone that have no fossils at all.)

NOTE: I’ve mentioned this once before in a previous lesson, but I will again point out that the ITB textbook doesn’t give any explanation of where the carbon was coming from to create the CaCO3 in the subterranean chamber. For now, we can assume that there was either carbon dioxide present in the water, or else there was a mineral source not previously mentioned, such as the pillars being made out of diamond, which is pure carbon and is the strongest substance we know of.) Bear in mind that theories inevitably get fine-tuned (or discarded) as time goes on.
