Basically Primary porosity is formed when the sediment is deposited. Secondary porosity is formed after sedimentary deposition (diagenisis).

That's the simplest way I can explain it!

Thanks petrobos! That's pretty simple indeed...

Can you also tell me what effective and ineffective porosity means??
