It can be a matter of hours or a process taking millions of years depending on the formation method of the rock.

The conditions under which the rock forms, such as temperature, pressure, and the composition of the mineral-rich fluid, can influence how long it takes for minerals to form within a rock. The rate of cooling and crystallization of magma or lava can also affect the timing of mineral formation within a rock. Additionally, factors like the presence of nucleation sites or impurities in the rock can impact the speed of mineral growth.
Unknown, but one theory is appx 240m years. There is much that is still not understood about the mysterious geode.
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.
Loam soil forms over hundreds to thousands of years through the gradual weathering and decomposition of rocks, minerals, and organic matter. The specific time it takes for loam soil to form can vary depending on factors such as climate, vegetation, and geological conditions.

Different minerals take different amounts of time.

i believe it takes 100 years to form a delta

Non-renewable Minerals are those minerals that cannot be recycled or takes a very long time to reform and can get totally depleted when extracted, for example, Petroleum.

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 takes about as long as a water cycle
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.
