Geological Processes and Rock Types

Sedimentary Rocks:

• Formed from the accumulation of sediment.
• Composed of materials like clay and marine animal remains.

Metamorphic Rocks:

• Created when existing rocks undergo change due to heat and pressure.
• Examples include marble (from limestone) and gneiss (from granite).

Key Mineral Transitions:

• Clay can transform into shale before turning into more complex metamorphic rocks.
• Organic materials can convert into graphite under certain conditions.

Important Elements:

• Associated with metals like gold and silver found in sedimentary processes.
