Question

Describe how mudstone forms.

Answer 1

you have any ideas on how this happens

Answer 2

nope:)

Answer 3

hope this helps
Mudstone is mostly composed of clay and silt particles; it is formed in a water-driven depositional environment characterized by a fast moving narrow flow that suddenly opens up into a very wide, slow moving flow, such as a river delta. The fast moving water carries a sediment load along with a makeup determined a great deal by the speed of the flow. The greater the speed of the flow, the heaview and larger are the objects it can carry down stream.

So when the fast and narrow flow suddenly opens up and gets very broad and very shallow the heavier particles drop out almost immediately, leaving the smaller, lighter particles to cary a little further, settling to the bottom in smooth, even layers. These lighter particles are composed of very small and very fine sand, silt, and the greatest component of the load is clay; with some minor organic material mixed for good measure.

These layers are laid down continuously, building up with each successive heavy flow coming down the river (or stream), new layers building on top of each previous layer, pushing then down, down, down, squeezing the water out from between the grains and platelets. When these layers have been compressed with the high pressure of overburden long enough, some minor "silicification" takes place between the particles from the sand grains contribution of silica in solution. This weakly 'binds' the mudstone together in thin plates. If the mudstone undergoes high heat as well as high pressure, it may metamorphose into slate
