2. How to Proterozoic marine sediments produce deposits?
- They have iron ore deposits e.g magnetite. They are formed when dissolved iron compounds become oxidised by oxygen released by photosynthesis producing insoluble iron oxide deposits-occurred mainly between 2.5 y + 1.8 billion yrs ago

3. What does laskys principle state?
- as purity of mineral increases amount of mineral present decreases
- states that in general as the purity of the mineral decreases, the amount of mineral present increases exponentially. So problem with future mineral supplies is not the quantity that exists but the need to develop methods to exploit low grade deposit
- states that in general as the purity of the mineral decreases, the amount of mineral present increases exponentially
4. What is fractional crystillisation?
- soon after the batholith is formed exploitation is now possible.
- A mix of minerals which cant be exploited are separated and deposited
- A mix of minerals which cant be exploited are separated and deposited soon after the batholith is formed exploitation is now possible.
- A mix of minerals which cant be exploited are separated and deposited soon after the batholith is formed
5. What are alluvial deposits?
- These are processes that involve materials carried and separated by flowing H20 , the ability of water to carry solids depends on the velocity of water and density of solids .
