===Chemical Processes===
In closed lakes, deposition of chemically processed sediments are common. There are many ions that are abundant in lake, but mostly carbonates are the most present. The evaporite deposits contain many evaporite minerals, such as gypsum, anhydrite, halite, and sylvite. The pH of lake is about 6 to 9, but it can become asidic in some volcanic lakes, and more alkaline in closed desert lakes.
