I see you are a motor cycle enthusiast so I will attempt to use the analogy of a road. Assume there is a 40 km long sloping hill (conduit) and there is a section of the road that near the top that is sand and gravel (sulphides). A huge rainfall starts (magma event) and starts pouring down the hill and hits the sandy section and starts to pick up the sand.

The water changes colour (saturation level) and changes in density (flow properties) and keeps running down the hill and hits several potholes(what we call (embayments) located all over the road and the sand starts to settle out and the heavier stuff falls to the bottom (massive sulphides) of the potholes but the water above is still murky (disseminated sulphides).

The rain stops and everything settles out. Then another rain event happens (second magma pulse) and the process starts over again but new channels formed during the first event direct the water flow as well as the slope of the hill in places has now changed so some of the water may flow off into the ditch. As well as after the first event they changed the source of the sand (new minerals) so mixing of the different types of sand occur.

Now the road crew comes out with a fire hose (hydrothermal alteration) to clean up. They wash the road with the force of the water changing what it looks like and again moving some of the sand around again.

Now this whole cycle happens several times and every time it does it changes where the sand ends up but in general the sand that settled to the bottom of the potholes is not affected. The sand on top of the road can be more easily reworked and further concentrated and form new layers in the potholes or fill new cracks.

The last stage is they repave the road (rock cap) and cover everything up. So the next road crew comes in (the exploration geos) and have no idea what lies below!!!

Hope this helps.
