The chemical reaction that forms the product mineral happens almost instintaneously, but for great amounts of the mineral to form depends on how much of your reactants are present, the temperature, and many other factors. Some take a few seconds and some take millions of years to form a set mass of your mineral.
Different minerals take different amounts of time.
Unknown, but one theory is appx 240m years. There is much that is still not understood about the mysterious geode.
The mineral family that tends to form long needlelike crystals is the amphibole group. Examples of minerals in this group include hornblende and tremolite. These minerals are silicate minerals with a double chain structure, which contributes to their characteristic needlelike crystal habit.
It can take hundreds to thousands of years to form fertile soil, depending on the conditions and processes involved. Factors such as climate, vegetation, minerals, and erosion play a role in the rate of soil formation.

Rock minerals form from lava, magma or solutions.
It typically takes millions of years to form sandstone. It is a sedimentary rock formed by the accumulation and cementation of sand grains over time. Factors such as pressure, temperature, and the presence of minerals influence the process.

Sodalite typically forms over hundreds to thousands of years in environments with abundant sodium and aluminum-rich minerals. The exact time it takes for sodalite to form depends on the specific geological conditions, such as temperature, pressure, and availability of the necessary elements.
It takes about 13.99 billion years for a galaxy to form.
