Limestone: Earth’s Carbonate Engine

Limestone is more than just a sedimentary rock — it is the foundation of landscapes, civilizations, and global industry. Formed in warm, shallow seas and freshwater systems, limestone records ancient life, ocean chemistry, and climate history. From fossil-rich marine deposits to rapidly forming travertine terraces, this carbonate rock tells the story of Earth’s dynamic systems. In this video, we break down: 🔹 What limestone is and how it forms 🔹 Marine and freshwater formation environments 🔹 Major limestone types (fossiliferous, chalk, coquina, oolitic, travertine) 🔹 Karst systems and groundwater flow 🔹 Geophysical and geochemical exploration methods 🔹 Economic importance in cement, steel, agriculture, and construction 🔹 Its scientific role in carbon cycling and Earth history Whether you are a geology student, mining professional, engineer, or Earth science enthusiast — this is your complete guide to limestone. Welcome to Geology Dean — where we turn rocks into knowledge. #Limestone #SedimentaryRocks #CarbonateRocks
